We are thrilled to announce the release of Tungsten Clustering & Tungsten Replicator v6.1.22! This release brings several important bug fixes and behavior changes to enhance the performance and stability of the Tungsten products. Let's dive into the release notes to explore the exciting updates.
Installation and Deployment
RPM Package Script
We have resolved a
NullPointerException error that occurred at startup when applying to PostgreSQL. This fix ensures a more stable replication process.
CREATE TABLE AS SELECT
Due to a change in the way MySQL logs
CREATE TABLE AS SELECT in the Binary Logs starting from v8.0.20, these transactions would previously fail. However, with this release, these statements will now replicate successfully. Please note that in the event of a failure during the data load, the initial CREATE statement won't be rolled back. Exercise caution when using this type of DDL.
JSON Field Extraction
We have fixed an issue where an extracted JSON field could be invalid, with doubled commas in JSON arrays. This ensures the accuracy and integrity of the replicated data.
Improved Metadata Query
We have optimized a query used by Tungsten when fetching tables metadata such as column names and datatypes. This enhancement improves the performance, especially against older MySQL versions with numerous databases and tables.
Please note that this optimized query is not enabled by default in this release. To enable it, use the following command:
Proxy Mode Logging
This fix removes extra logging for each
SET xxx statement in proxy mode. This eliminates log pollution and prevents performance degradation caused by excessive logging. It ensures a more responsive connector and prevents memory exhaustion.
We encourage all users of v6 of Tungsten Clustering & Tungsten Replicator to upgrade to version 6.1.22 to benefit from these improvements and bug fixes. As always, you can find the latest release on our website.
Thank you for your continued support and feedback. We are committed to delivering exceptional products and look forward to providing more exciting updates in the future.
