Running tpm uninstall will now save all of the Tungsten database tracking schemas for later use. There is also a new tpm keep command, which allows the tracking schemas to be saved to disk at any time in multiple formats (.json, .dmp and .cmd)

Issues: CT-2131

Added tpm flag deploy-systemd as a more meaningful alias to install

Issues: CT-2152

Added a new option --preserve-schema to the tpm uninstall command in order to leave the tracking schema in the database.

Issues: CT-561

A new command tpm cert has been added to aid in the creation, rotation and management of certificates for all areas of Tungsten.

Known limitations: Percona 5.6, and all versions of MariaDB do not provide the mysql_ssl_rsa_setup command required by tpm cert gen mysqlcerts.

Issues: CT-2085

The tpm diag command now supports the --skipsudo and --nosudo arguments to prevent operations from using the sudo command. Using this option may result in tpm diag skipping/failing various gathers due to a lack of access.

It is now possible to configure the PostgreSQL applier in Batch mode.

Issues: CT-2031

Added a new ddlscan template, ddl-mysql-postgres-staging.vm, to allow generation of staging table DDL for the PostgreSQL batch applier.

Issues: CT-2136

A new applier is now available that replicates to csv files on S3 storage.

For more information, see S3 Applier Docuemntation

Issues: CT-606

Upgraded JGroups library to 4.2.22

Issues: CT-2011

A new shardbyrules filter has been added that will allow rule based sharding of replication based on user confgurable rules that would allow sharding at table level, whereas previoulsy sharding would only be handled at schema level.

For more information, see shardbyrules Filter Docuemntation

Issues: CT-2164

Prometheus exporters now provide the ssl cert expiration date as an epoch value in addition to the label.

Issues: CT-2099

Prometheus libraries have been upgraded from version 0.8.1 to 0.16.0

Issues: CT-2166

Fixed RPM package script to run tpm install instead of tpm update when installing the rpm

Issues: CT-2130

tpm uninstall would sometimes print "ERROR >> db1 >> undefined method '+' for nil:NilClass"

Issues: CT-2104

The tpm command now searches more places to locate shell commands that are called, especially useful when $CONTINUENT_ROOT/share/env.sh is not sourced.

Issues: CT-2182

tprovision will now print an error message and exit if the MySQL datadir does not exit.

Issues: CT-1901

Fixes an issue with the ddl-mysql-postgres.vm ddlscan template that caused varchar datatype lengths to be parsed incorrectly.

Issues: CT-2019

Fixed a NullPointerException error occurring at startup when applying to PostgreSQL

Issues: CT-2021

Improved a query that is run by Tungsten when fetching tables metadata (column names, datatypes, etc). While it is not generally needed, the unoptimized query can run badly (especially) against old mysql versions with a lot of databases / tables. For now, the new optimized query is not used by default, but this could change in some future version.

This can be enabled by using the following property :

property=replicator.datasource.global.connectionSpec.usingOptimizedMetadataQuery=true

Issues: CT-2077

Fixed an issue while processing geometry data with SRID 4326 that would swap longitude and latitude. This applies only to MySQL 8, as prior MySQL versions do not allow specifying the order when applying a WKB (Well-known binary) to MySQL

Issues: CT-2172
