Change Log

[wesql-server:8.0.35-0.1.0_beta4.38] - 2024-12-23​

New Feature​

  • Replication: WeSQL replication is designed as a cloud-native replication solution that uses object storage as a medium for binlog copying between one WeSQL Source database and one or more other Replica databases. WeSQL replication uses asynchronous replication, periodically detecting changes in the binlog in the Source object storage to replicate data to the local Replica Server and replay it. The feature is controlled by the parameter binlog_archive_replica, and it is only enabled when set to binlog_archive_replica=true. More information, refer to Replication.

Improvements​

  • Object Storage

    • Improve time accuracy of waiting object storage lease lock to reduce startup time. Change the object storage lease lock timeout from 12s to 8s.
    • Add parameter objectstore_lease_lock_timeout for object storage lease lock. If 0, lease lock is disabled. The default value is 8s.

  • Clone Instance

Adjust the source object storage parameter names when cloning instances to facilitate the use of these parameters in WeSQL Replication.

  • Rename parameter initialize_from_objectstore to initialize_from_source_objectstore.
  • Rename parameter initialize_objectstore_provider to source_objectstore_provider.
  • Rename parameter initialize_objectstore_region to source_objectstore_region.
  • Rename parameter initialize_objectstore_endpoint to source_objectstore_endpoint.
  • Rename parameter initialize_objectstore_use_https to source_objectstore_use_https.
  • Rename parameter source_objectstore_bucket to source_objectstore_bucket.
  • Rename parameter initialize_repo_objectstore_id to source_objectstore_repo_id.
  • Rename parameter initialize_branch_objectstore_id to source_objectstore_branch_id.
  • Rename parameter initialize_smartengine_objectstore_data to source_objectstore_smartengine_data.

Bugs Fixed​

  • Snapshot
    • When clone an new instance, if the bucket parameter source_objectstore_bucket of the source instance is different from the objectstore_bucket parameter of the cloned instance, the initialization will fail.
  • Smartengine
    • Fix uneven data writes cause wal checkpoint stalls. Subtables with empty memtable do not advance their recovery points causing the WAL checkpoint to stall while waiting for all subtables to align at a consistent WAL position.
  • Binlog
    • Fix the local binlog to be unable to be purged that has been persisted, When executing purge binlog(auto purge or manual purge).
