# Background knowledge current we support to set compression on ManagedLedger and ManagedCursor metadata by `managedLedgerInfoCompressionType` and `managedCursorInfoCompressionType` # Motivation sometimes the metadata is too small to compress. so a size based config is needed. # Goals ## In Scope add config to set size threshold for compression on metadata. `managedLedgerInfoCompressionSizeThreshold` `managedCursorInfoCompressionSizeThreshold` default value is 0. so this won't change the behaviour if set `managedLedgerInfoCompressionType` if the setting is set, only compress the metadata if the persistent size if above the setting. # High Level Design add config in `ServerConfiguration` when init `ManagedLedgerConfig` the setting is passed. when persistent metadata the config will affect the compression logic. ### Configuration new configuration: `managedLedgerInfoCompressionSizeThreshold` `managedCursorInfoCompressionSizeThreshold` # Backward & Forward Compatability ## Revert the compression logic is transparent. if remove the config nothing changed. # Links pr that introduce metadata compression: https://github.com/apache/pulsar/pull/11490 https://github.com/apache/pulsar/pull/14542 -- This is an automated message from the Apache Git Service.
