Improve LogMiner query performance by reducing REGEXP_LIKE disjunctions

    XMLWordPrintable

Details

    Description

      The Oracle connector presently takes every schema and table include value and builds a REGEXP_LIKE predicate for each entry. This can lead to poor performance when a large number of tables or schemas are being specified. We should look to build this expression using a singular REGEXP_LIKE predicate for schema include/excludes and one for table include/excludes or pulling this logic into the connector's Java code for better performance.
