makssent opened a new pull request, #36928: URL: https://github.com/apache/shardingsphere/pull/36928
Ref #33781. Changes proposed in this pull request: - FirebirdColumnSizeLoader now retrieves both COLUMN_SIZE and SEGMENT_SIZE for BLOB fields during metadata collection. This enables obtaining the actual length for all dynamic data types. - In FirebirdPrepareStatementCommandExecutor, the calculated column length is stored in the columnLength variable, which is then directly passed to FirebirdReturnColumnPacket and used when forming the DESCRIBE response. As a result, the client receives accurate, real column sizes. - During metadata loading, the computed sizes are stored in the thread-safe FirebirdSizeRegistry and synchronized at the table level. This ensures that additional queries are executed only once — during metadata collection — while subsequent accesses use the cached data. --- Before committing this PR, I'm sure that I have checked the following options: - [X] My code follows the [code of conduct](https://shardingsphere.apache.org/community/en/involved/conduct/code/) of this project. - [X] I have self-reviewed the commit code. - [X] I have (or in comment I request) added corresponding labels for the pull request. - [ ] I have passed maven check locally : `./mvnw clean install -B -T1C -Dmaven.javadoc.skip -Dmaven.jacoco.skip -e`. - [ ] I have made corresponding changes to the documentation. - [ ] I have added corresponding unit tests for my changes. - [ ] I have updated the Release Notes of the current development version.
