Version End of Life. 31 July 2020
Release 6.0.0 is a feature and bugfix release. This release contains the following key fixes:
Added PostgreSQL applier support.
Added support for custom primary key field selection for source tables that cannot be configured with a primary key within the database.
Added a new filter for including whole of transaction metadata information into each event.
Added support for extended transaction information within the Kafka applier so that all the messages for a given transaction can be identified.
The following changes have been made to Tungsten Replicator and may affect existing scripts and integration tools. Any scripts or environment which make use of these tools should check and update for the new configuration:
The Kafka applier now supports the inclusion of transaction information into each Kafka message broadcast, including the list of schema/tables and row counts for the entire transaction, as well as information about whether the message is the first or last message/row within an overall transaction. The transaction information can also be sent as a separate message on an independent Kafka topic.
Issues: CT-496, CT-586
For more information, see Optional Configuration Parameters for Kafka (in [Tungsten Replicator 6.0 Manual]).
Experimental support for writing row-based data through SQL into PostgreSQL has been added back to the replicator. This includes basic support fr the replication of the data. Currently databases and tables must be created by hand. A future release will incorporate full support for DDL translation.
pkey (in [Tungsten Replicator 7.0 Manual]) has been extended
to support the specification of custom primary key fields. This
enables fields in the source data to be marked as primary keys
even if the source database does not have the keys specified.
This is useful for heterogeneous loading of data where a unique
key may exist, but cannot be defined due to the application or
database that created the tables.
A new filter,
rowaddtxninfo (in [Tungsten Replicator 7.0 Manual]) has
been added which embeds row counts, both total and per
schema/table, to the metadata for a THL event/transaction.
An internal optimization within the replicator that would
attempt to optimise row-based information and operations has
been removed. The effects of the optimization were actually seen
in very few situations, and it duplicated work and operations
performed by the
pkey (in [Tungsten Replicator 7.0 Manual]) filter.
Unfortunately the same optimization could also cause issues
within heterogeneous deployments with the removal of
The internal storage of the MySQL server ID has been updated to support larger server IDs. This works with any MySQL deployment, but has been specifically expanded to work better with some cloud deployments where the server ID cannot be controlled.
