/**
  @file storage/perfschema/pfs_dd_version.h
  Performance schema data dictionary version.
*/
 
/**
  The version of the current performance_schema database schema.
  Version numbering forms a name space,
  which needs to be unique across all MySQL versions,
  even including forks.
 
  This version number is stored on disk in the data dictionary.
  Every time the performance_schema structure changes,
  this version number must change.
 
  Do not use a naive 1, 2, 3, ... N numbering scheme,
  as it requires an authoritative registry to assign numbers.
  This can not work in a distributed development environment,
  even less with forks, patches and back ports done by third parties.
 
  The numbering to use is the MySQL version number
  of the first MySQL version that published a given database schema.
  The format is Mmmdd with M=Major, m=minor, d=dot,
  so that MySQL 8.0.4 is encoded as 80004.
 
  In case of -dash version numbers, encode MySQL 8.12.34-56 as 8123456.
 
  Historical version number published in the data dictionary:
 
  1:
 
  Introduced in MySQL 8.0.3 by WL#7900.
  Never published in a GA version, abandoned.
 
  80004:
 
  performance_schema tables changed in MySQL 8.0.4 are
  - setup_threads (created)
  - setup_instruments (modified)
  - variables_info (modified)
  - setup_timers (removed)
  - metadata_locks (modified, added column COLUMN_NAME)
  - replication_connection_configuration (modified)
  - instance_log_resource (created)
 
  80005:
 
  performance_schema tables changed in MySQL 8.0.5 are
  - all, changed UTF8 (aka UTF8MB3) to UTF8MB4.
 
  80006:
 
  performance_schema tables changed in MySQL 8.0.6 are
  - variables_info.set_time precision changed from 0 to 6.
 
  80011:
 
  Version bump from 8.0.6 to 8.0.11,
  versions [8.0.5 - 8.0.10] inclusive are abandoned.
  performance_schema tables changed in MySQL 8.0.11 are
  - instance_log_resource was renamed to log_resource.
 
  80014:
 
  performance_schema tables changed in MySQL 8.0.14 are

  - events_statements_history, added column QUERY_ID
  - events_statements_history_long, added column QUERY_ID
 
  80015:
 
  performance_schema.keyring_keys
 
  80017: -- WARNING, EXPOSED BY MySQL 8.0.16 --
 
  Unfortunately, MySQL 8.0.16 claim the 80017 tag, due to a bad merge.
  performance_schema tables changed in MySQL 8.0.16
  - replication_connection_configuration, added column NETWORK_NAMESPACE
 
  800171: -- WARNING, EXPOSED BY MySQL 8.0.17 --
    ---------------------------------------------------------------------
    IMPORTANT NOTE:
    The release 8.0.16 made use of version 80017 incorrectly, which makes
    the upgrade from 8.0.16 to 8.0.17 release immutable. This was
    introduced by WL#12720.
 
    In order to allow upgrade from 8.0.16 to 8.0.17, we choose the new
    version number as 800171 for 8.0.17 release. Going forward the
    release 8.0.18 would use 80018.
 
    Note that, any comparison between two PFS version numbers should be
    carefully done.
