    RETURNS VARCHAR(64) 
    COMMENT '
             Description
             -----------

             Takes a raw file path, and attempts to extract the schema name from it.

             Useful for when interacting with Performance Schema data 
             concerning IO statistics, for example.

             Currently relies on the fact that a table data file will be within a 
             specified database directory (will not work with partitions or tables
             that specify an individual DATA_DIRECTORY).

             Parameters
             -----------

             path (VARCHAR(512)):
               The full file path to a data file to extract the schema name from.

             Returns

             Formats a normalized statement, truncating it if it is &gt; 64 characters long by default.

             To configure the length to truncate the statement to by default, update the `statement_truncate_len`
             variable with `sys_config` table to a different value. Alternatively, to change it just for just

DROP FUNCTION IF EXISTS ps_thread_trx_info;

DELIMITER $$

CREATE DEFINER='mariadb.sys'@'localhost' FUNCTION ps_thread_trx_info (
        in_thread_id BIGINT UNSIGNED
    ) RETURNS LONGTEXT
    COMMENT '
             Description
             -----------

             Returns a JSON object with info on the given threads current transaction, 
             and the statements it has already executed, derived from the
             performance_schema.events_transactions_current and
             performance_schema.events_statements_history tables (so the consumers 
             for these also have to be enabled within Performance Schema to get full
             data in the object).

             When the output exceeds the default truncation length (65535), a JSON error
             object is returned, such as:

             { &quot;error&quot;: &quot;Trx info truncated: Row 6 was cut by GROUP_CONCAT()&quot; }

             Similar error objects are returned for other warnings/and exceptions raised
             when calling the function.

             The max length of the output of this function can be controlled with the
             ps_thread_trx_info.max_length variable set via sys_config, or the
             @sys.ps_thread_trx_info.max_length user variable, as appropriate.

             Parameters
             -----------

             in_thread_id (BIGINT UNSIGNED):
               The id of the thread to return the transaction info for.

             Example
             -----------

DROP FUNCTION IF EXISTS sys_get_config;

DELIMITER $$

CREATE DEFINER='mariadb.sys'@'localhost' FUNCTION sys_get_config (
        in_variable_name VARCHAR(128),
        in_default_value VARCHAR(128)
    )
    RETURNS VARCHAR(128)
    COMMENT '
             Description
             -----------

             Returns the value for the requested variable using the following logic:

                1. If the option exists in sys.sys_config return the value from there.
                2. Else fall back on the provided default value.

             Notes for using sys_get_config():

                * If the default value argument to sys_get_config() is NULL and case 2. is reached, NULL is returned.
                  It is then expected that the caller is able to handle NULL for the given configuration option.
                * The convention is to name the user variables @sys.&lt;name of variable&gt;. It is &lt;name of variable&gt; that
                  is stored in the sys_config table and is what is expected as the argument to sys_get_config().
                * If you want to check whether the configuration option has already been set and if not assign with
                  the return value of sys_get_config() you can use IFNULL(...) (see example below). However this should
                  not be done inside a loop (e.g. for each row in a result set) as for repeated calls where assignment
                  is only needed in the first iteration using IFNULL(...) is expected to be significantly slower than
                  using an IF (...) THEN ... END IF; block (see example below).

             Parameters
             -----------

             in_variable_name (VARCHAR(128)):
               The name of the config option to return the value for.

             in_default_value (VARCHAR(128)):
               The default value to return if the variable does not exist in sys.sys_config.

             Returns
             -----------

             VARCHAR(128)

             Example
             -----------

-- IMPORTANT
-- If you update this view, also update the &quot;5.7+ and the Performance Schema disabled&quot;
-- query in procedures/diagnostics.sql

-- View: metrics
-- 
-- Creates a union of the following information:
--
--    *  performance_schema.global_status
--    *  information_schema.INNODB_METRICS
--    *  Performance Schema global memory usage information
--    *  Current time
--
-- This is the same as the metrics_56 view with the exception that the global status is taken from performance_schema.global_status instead of
-- from the Information Schema. Use this view if the MySQL version is 5.7.6 or later and show_compatibility_56 = OFF.
-- See also https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_show_compatibility_56
-- 
-- For view has the following columns:
-- 
--    * Variable_name: The name of the variable
--    * Variable_value: The value of the variable
--    * Type: The type of the variable. This will depend on the source, e.g. Global Status, InnoDB Metrics - ..., etc.
--    * Enabled: Whether the variable is enabled or not. Possible values are 'YES', 'NO', 'PARTIAL'.
--      PARTIAL is currently only supported for the memory usage variables and means some but not all of the memory/% instruments
--      are enabled.

        IN in_synonym VARCHAR(64)
    )
    COMMENT '
             Description
             -----------

             Takes a source database name and synonym name, and then creates the 
             synonym database with views that point to all of the tables within
             the source database.

             Useful for creating a &quot;ps&quot; synonym for &quot;performance_schema&quot;,
             or &quot;is&quot; instead of &quot;information_schema&quot;, for example.

             Parameters
             -----------

             in_db_name (VARCHAR(64)):
               The database name that you would like to create a synonym for.
             in_synonym (VARCHAR(64)):
               The database synonym name.

             Example
             -----------

    COMMENT '
             Description
             -----------

             Takes the query in the argument and executes it using a prepared statement. The prepared statement is deallocated,
             so the procedure is mainly useful for executing one off dynamically created queries.

             The sys_execute_prepared_stmt prepared statement name is used for the query and is required not to exist.


             Parameters
             -----------

             in_query (longtext CHARACTER SET UTF8):
               The query to execute.

DROP PROCEDURE IF EXISTS diagnostics;

DELIMITER $$

CREATE DEFINER='mariadb.sys'@'localhost' PROCEDURE diagnostics (
        IN in_max_runtime int unsigned, IN in_interval int unsigned,
        IN in_auto_config enum ('current', 'medium', 'full')
    )
    COMMENT '
             Description
             -----------

             Create a report of the current status of the server for diagnostics purposes. Data collected includes (some items depends on versions and settings):

                * The GLOBAL VARIABLES
                * Several sys schema views including metrics or equivalent (depending on version and settings)
                * Queries in the 95th percentile
                * Several ndbinfo views for MySQL Cluster
                * Replication (both master and slave) information.

             Some of the sys schema views are calculated as initial (optional), overall, delta:

                * The initial view is the content of the view at the start of this procedure.
                  This output will be the same as the the start values used for the delta view.
                  The initial view is included if @sys.diagnostics.include_raw = ''ON''.
                * The overall view is the content of the view at the end of this procedure.
                  This output is the same as the end values used for the delta view.
                  The overall view is always included.
                * The delta view is the difference from the beginning to the end. Note that for min and max values
                  they are simply the min or max value from the end view respectively, so does not necessarily reflect
                  the minimum/maximum value in the monitored period.
                  Note: except for the metrics views the delta is only calculation between the first and last outputs.
             
             Requires the SUPER privilege for &quot;SET sql_log_bin = 0;&quot;.

             Versions supported:
                * MySQL 5.6: 5.6.10 and later
                * MySQL 5.7: 5.7.9 and later

             Parameters
             -----------

             in_max_runtime (INT UNSIGNED):
               The maximum time to keep collecting data.
               Use NULL to get the default which is 60 seconds, otherwise enter a value greater than 0.
             in_interval (INT UNSIGNED):
               How long to sleep between data collections.
               Use NULL to get the default which is 30 seconds, otherwise enter a value greater than 0.
             in_auto_config (ENUM(''current'', ''medium'', ''full''))
               Automatically enable Performance Schema instruments and consumers.
               NOTE: The more that are enabled, the more impact on the performance.
               Supported values are:
                  * current - use the current settings.
                  * medium - enable some settings.
                  * full - enables all settings. This will have a big impact on the
                           performance - be careful using this option.
               If another setting the ''current'' is chosen, the current settings
               are restored at the end of the procedure.


             Configuration Options
             ----------------------

             sys.diagnostics.allow_i_s_tables
               Specifies whether it is allowed to do table scan queries on information_schema.TABLES. This can be expensive if there
               are many tables. Set to ''ON'' to allow, ''OFF'' to not allow.
               Default is ''OFF''.

             sys.diagnostics.include_raw
               Set to ''ON'' to include the raw data (e.g. the original output of &quot;SELECT * FROM sys.metrics&quot;).
               Use this to get the initial values of the various views.
               Default is ''OFF''.

             sys.statement_truncate_len
               How much of queries in the process list output to include.
               Default is 64.

             sys.debug
               Whether to provide debugging output.
               Default is ''OFF''. Set to ''ON'' to include.

CREATE DEFINER='mariadb.sys'@'localhost' PROCEDURE ps_trace_statement_digest (
        IN in_digest VARCHAR(32),
        IN in_runtime INT, 
        IN in_interval DECIMAL(2,2),
        IN in_start_fresh BOOLEAN,
        IN in_auto_enable BOOLEAN
    )
    COMMENT '
             Description
             -----------

             Traces all instrumentation within Performance Schema for a specific
             Statement Digest. 

             When finding a statement of interest within the 
             performance_schema.events_statements_summary_by_digest table, feed
             the DIGEST MD5 value in to this procedure, set how long to poll for, 
             and at what interval to poll, and it will generate a report of all 
             statistics tracked within Performance Schema for that digest for the
             interval.

             It will also attempt to generate an EXPLAIN for the longest running 
             example of the digest during the interval. Note this may fail, as:

                * Performance Schema truncates long SQL_TEXT values (and hence the 
                  EXPLAIN will fail due to parse errors)
                * the default schema is sys (so tables that are not fully qualified
                  in the query may not be found)
                * some queries such as SHOW are not supported in EXPLAIN.

             When the EXPLAIN fails, the error will be ignored and no EXPLAIN
             output generated.

             Requires the SUPER privilege for &quot;SET sql_log_bin = 0;&quot;.

             Parameters
             -----------

             in_digest (VARCHAR(32)):
               The statement digest identifier you would like to analyze
             in_runtime (INT):
               The number of seconds to run analysis for
             in_interval (DECIMAL(2,2)):
               The interval (in seconds, may be fractional) at which to try
               and take snapshots
             in_start_fresh (BOOLEAN):
               Whether to TRUNCATE the events_statements_history_long and
               events_stages_history_long tables before starting
             in_auto_enable (BOOLEAN):
               Whether to automatically turn on required consumers

             Example
             -----------

    COMMENT '
             Description
             -----------

             Dumps all data within Performance Schema for an instrumented thread,
             to create a DOT formatted graph file. 

             Each resultset returned from the procedure should be used for a complete graph

             Requires the SUPER privilege for &quot;SET sql_log_bin = 0;&quot;.

             Parameters
             -----------

             in_thread_id (BIGINT UNSIGNED):
               The thread that you would like a stack trace for
             in_outfile  (VARCHAR(255)):
               The filename the dot file will be written to
             in_max_runtime (DECIMAL(20,2)):
               The maximum time to keep collecting data.
               Use NULL to get the default which is 60 seconds.
             in_interval (DECIMAL(20,2)): 
               How long to sleep between data collections. 
               Use NULL to get the default which is 1 second.
             in_start_fresh (BOOLEAN):
               Whether to reset all Performance Schema data before tracing.
             in_auto_setup (BOOLEAN):
               Whether to disable all other threads and enable all consumers/instruments. 
               This will also reset the settings at the end of the run.
             in_debug (BOOLEAN):
               Whether you would like to include file:lineno in the graph

    COMMENT '
             Description
             -----------

             Saves the current configuration of Performance Schema, 
             so that you can alter the setup for debugging purposes, 
             but restore it to a previous state.

             Use the companion procedure - ps_setup_reload_saved(), to 
             restore the saved config.

             The named lock &quot;sys.ps_setup_save&quot; is taken before the
             current configuration is saved. If the attempt to get the named
             lock times out, an error occurs.

             The lock is released after the settings have been restored by
             calling ps_setup_reload_saved().

             Requires the SUPER privilege for &quot;SET sql_log_bin = 0;&quot;.

             Parameters
             -----------

             in_timeout INT
               The timeout in seconds used when trying to obtain the lock.
               A negative timeout means infinite timeout.

             Example
             -----------

             mysql&gt; CALL sys.ps_setup_save(-1);

             Requires the SUPER privilege for &quot;SET sql_log_bin = 0;&quot;.

             Parameters
             -----------

             in_action (ENUM(''snapshot'', ''overall'', ''delta'', ''create_tmp'', ''create_table'', ''save'', ''cleanup'')):
               The action to take. Supported actions are:
                 * snapshot      Store a snapshot. The default is to make a snapshot of the current content of
                                 performance_schema.events_statements_summary_by_digest, but by setting in_table
                                 this can be overwritten to copy the content of the specified table.
                                 The snapshot is stored in the sys.tmp_digests temporary table.
                 * overall       Generate analyzis based on the content specified by in_table. For the overall analyzis,
                                 in_table can be NOW() to use a fresh snapshot. This will overwrite an existing snapshot.
                                 Use NULL for in_table to use the existing snapshot. If in_table IS NULL and no snapshot
                                 exists, a new will be created.
                                 See also in_views and @sys.statement_performance_analyzer.limit.
                 * delta         Generate a delta analysis. The delta will be calculated between the reference table in
                                 in_table and the snapshot. An existing snapshot must exist.
                                 The action uses the sys.tmp_digests_delta temporary table.
                                 See also in_views and @sys.statement_performance_analyzer.limit.
                 * create_table  Create a regular table suitable for storing the snapshot for later use, e.g. for
                                 calculating deltas.
                 * create_tmp    Create a temporary table suitable for storing the snapshot for later use, e.g. for
                                 calculating deltas.
                 * save          Save the snapshot in the table specified by in_table. The table must exists and have
                                 the correct structure.
                                 If no snapshot exists, a new is created.
                 * cleanup       Remove the temporary tables used for the snapshot and delta.

             in_table (VARCHAR(129)):
               The table argument used for some actions. Use the format ''db1.t1'' or ''t1'' without using any backticks (`)
               for quoting. Periods (.) are not supported in the database and table names.
               
               The meaning of the table for each action supporting the argument is:

                 * snapshot      The snapshot is created based on the specified table. Set to NULL or NOW() to use
                                 the current content of performance_schema.events_statements_summary_by_digest.
                 * overall       The table with the content to create the overall analyzis for. The following values
                                 can be used:
                                   - A table name - use the content of that table.
                                   - NOW()        - create a fresh snapshot and overwrite the existing snapshot.
                                   - NULL         - use the last stored snapshot.
                 * delta         The table name is mandatory and specified the reference view to compare the currently
                                 stored snapshot against. If no snapshot exists, a new will be created.
                 * create_table  The name of the regular table to create.
                 * create_tmp    The name of the temporary table to create.

             Default is to include all except ''custom''.


             Configuration Options
             ----------------------

             sys.statement_performance_analyzer.limit
               The maximum number of rows to include for the views that does not have a built-in limit (e.g. the 95th percentile view).
               If not set the limit is 100.

             sys.statement_performance_analyzer.view
               Used together with the ''custom'' view. If the value contains a space, it is considered a query, otherwise it must be
               an existing view querying the performance_schema.events_statements_summary_by_digest table. There cannot be any limit
               clause including in the query or view definition if @sys.statement_performance_analyzer.limit &gt; 0.
               If specifying a view, use the same format as for in_table.

             sys.debug
               Whether to provide debugging output.
               Default is ''OFF''. Set to ''ON'' to include.


             Example
             --------

             To create a report with the queries in the 95th percentile since last truncate of performance_schema.events_statements_summary_by_digest
             and the delta for a 1 minute period:

                1. Create a temporary table to store the initial snapshot.
                2. Create the initial snapshot.
                3. Save the initial snapshot in the temporary table.
                4. Wait one minute.
                5. Create a new snapshot.
                6. Perform analyzis based on the new snapshot.
                7. Perform analyzis based on the delta between the initial and new snapshots.

CREATE DEFINER='mariadb.sys'@'localhost' PROCEDURE table_exists (
        IN in_db VARCHAR(64), IN in_table VARCHAR(64),
        OUT out_exists ENUM('', 'BASE TABLE', 'VIEW', 'TEMPORARY', 'SEQUENCE', 'SYSTEM VIEW', 'TEMPORARY SEQUENCE')
    )
    COMMENT '
             Description
             -----------

             Tests whether the table specified in in_db and in_table exists either as a regular
             table, or as a temporary table. The returned value corresponds to the table that
             will be used, so if there''s both a temporary and a permanent table with the given
             name, then ''TEMPORARY'' will be returned.

             Parameters
             -----------

             in_db (VARCHAR(64)):
               The database name to check for the existence of the table in.

             in_table (VARCHAR(64)):
               The name of the table to check the existence of.

             out_exists ENUM('''', ''BASE TABLE'', ''VIEW'', ''TEMPORARY'', ''SEQUENCE'', ''SYSTEM VIEW'', ''TEMPORARY SEQUENCE''):
               The return value: whether the table exists. The value is one of:
                 * ''''                    - the table does not exist neither as a base table, view, sequence nor temporary table/sequence.
                 * ''BASE TABLE''          - the table name exists as a permanent base table table.
                 * ''VIEW''                - the table name exists as a view.
                 * ''TEMPORARY''           - the table name exists as a temporary table.
                 * ''SEQUENCE''            - the table name exists as a sequence.
                 * ''SYSTEM VIEW''         - the table name exists as a system view.
                 * ''TEMPORARY SEQUENCE''  - the table name exists as a temporary sequence.
