module: proxysql_manage_config
author: "Ben Mildren (@bmildren)"
short_description: Writes the proxysql configuration settings between layers.
description:
- The M(community.general.proxysql_global_variables) module writes the proxysql configuration
settings between layers. Currently this module will always report a
changed state, so should typically be used with WHEN however this will
change in a future version when the CHECKSUM table commands are available
for all tables in proxysql.
options:
action:
description:
- The supplied I(action) combines with the supplied I(direction) to
provide the semantics of how we want to move the I(config_settings)
between the I(config_layers).
choices: [ "LOAD", "SAVE" ]
required: True
config_settings:
description:
- The I(config_settings) specifies which configuration we're writing.
choices: [ "MYSQL USERS", "MYSQL SERVERS", "MYSQL QUERY RULES",
"MYSQL VARIABLES", "ADMIN VARIABLES", "SCHEDULER" ]
required: True
direction:
description:
- FROM - denotes we're reading values FROM the supplied I(config_layer)
and writing to the next layer.
TO - denotes we're reading from the previous layer and writing TO the
supplied I(config_layer)."
choices: [ "FROM", "TO" ]
required: True
config_layer:
description:
- RUNTIME - represents the in-memory data structures of ProxySQL used by
the threads that are handling the requests.
MEMORY - (sometimes also referred as main) represents the in-memory
SQLite3 database.
DISK - represents the on-disk SQLite3 database.
CONFIG - is the classical config file. You can only LOAD FROM the
config file.
choices: [ "MEMORY", "DISK", "RUNTIME", "CONFIG" ]
required: True
