Version End of Life. Not Yet Set
Release 5.4.1 contains both significant improvements as well as some needed bugfixes.
If using the dropcolumn filter during extraction, in conjunction with the Batch Applier (eg Replicating to Redshift, Hadoop, Vertica) writes would fail with a CSV mismatch error due to gaps in the THL Index.
However, for JDBC appliers, the gaps are required to ensure the correct column mapping
To handle the two different requirements, a new property has been added to the filter to control whether or not to leave the THL index untouched (the default) or to re-order the Index ID's
If applying to Batch targets, then the following property should be added to your configuration. The property is not required for JDBC targets.
