This release also contains an improvement for logical replication performance. This improvement, enabled as a write-through cache, will help improve the performance of Aurora PostgreSQL when continuously reading a logical replication stream (to minimize replication lag). Each replication slot can read recent data from the cache instead of Aurora Storage. In addition to performance improvements, the cache can help reduce I/O. The cache is available for Aurora PostgreSQL versions 14.5, 13.8, 12.12, and 11.17.
You can initiate a minor version upgrade manually by modifying your DB cluster. Please review the Aurora documentation to learn more. This release is available in all AWS Regions and the AWS GovCloud (US) Regions.
