> Tech Debt elimination. Cleanup and standardize CompactionTxnHandler.java considering the following items, but not limited to them:
>  * Check for proper javadoc
>  * Remove unnecessary logging, adjust log level properly
>  * Consistent transaction handling:
>  ** No rollback for selects
>  ** Exception in case of update count mismatch (single row update returns 0 or >1 for updated rows)
>  ** Review proper usage of RetrySemantics.* annotations
>  * Common private template methods for 'infrastructure' code (same try-catch logic, connection handling, etc: possibly with spring-jdbc
>  * Replace inline hardcoded and assembled SQL statements with parameterized constants.
