## Description This PR optimizes relational insertTablets handling in the Java Session client. - Add a merge switch for relational tablets in Session builders and pools. - Reuse column index maps when checking and merging relational tablets. - Avoid unnecessary bitmap creation during merge. - Copy tablet data column-by-column with array copy. - Auto-disable merge after consecutive misses or when merge overhead is too high. - Add an ignored integration test for manually comparing insertTablet and insertTablets performance as tablet count increases on the same table. ## Tests - mvn test -pl iotdb-client/session -am "-Dtest=SessionTest#testMergeRelationalTabletsWithHighDuplicatedColumns+testMergeRelationalTabletsSkipLowDuplicatedColumnsAndDifferentTables+testMergeRelationalTabletsStopAfterConsecutiveMisses+testMergeRelationalTabletsResetConsecutiveMissesAfterMerge+testMergeTabletsDisabledWhenMergeCostExceedsHalfOfInsertCost+testMergeTabletsKeepsEnabledWhenMergeCostIsNotTooHigh+testEnableMergeTabletsUsingBuilder" "-DfailIfNoTests=false" "-Dsurefire.failIfNoSpecifiedTests=false" - mvn test-compile -pl integration-test -am -P with-integration-tests -DskipTests "-Drat.skip=true" - mvn verify "-DskipUTs" "-Dit.test=IoTDBSessionRelationalIT#compareInsertTabletAndInsertTabletsPerformanceWithIncreasingTabletCount" "-DfailIfNoTests=false" "-Dfailsafe.failIfNoSpecifiedTests=false" "-Drat.skip=true" -pl integration-test -am -PTableSimpleIT -P with-integration-tests -- This is an automated message from the Apache Git Service.
