  • Optimized the batch package processing logic.
  • Optimized the resetConnection processing logic.

2024-07-30

2.24.06.000

  • Added binlog pulling through the proxy instance kernel.
  • Fixed the issue that after transaction splitting is enabled, read requests after SELECT FOR UPDATE are sent to the primary node.

2024-05-07

2.24.03.000

Added the feature for assigning requests to row and column store nodes.

2024-01-15

2.23.12.000
