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 report command now displays the security-specific information for each channel shown, including file paths and tpm options. Security information and tpm options for each channel will also be shown when --extra is used with --list.

Also added the tpm ask certs command with expiry and sha2566 info per alias, along with the tpm ask certtpm and tpm ask certlocations commands with reference information about the security.properties file.

Added help text for tpm ask --long which shows the key/variable name along with the value. The tmonitor -t test command now shows only the actual Tungsten-specific metrics lines.

Added tmonitor -T test to show metrics help and headers along with actual tungsten_* metrics lines.

Issues: CT-2088

tungsten show processlist could error with a disconnection message listing connections disconnected on the mysql server side.

Issues: CT-2112

The tpm diag command now captures the output of cctrl> cluster topology validate

Issues: CT-2115

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.

Issues: CT-2146

The tungsten_send_diag command has a new argument --all which will tell the tpm diag command to gather all hosts with -a, and this replaces the previous method for gathering all hosts for tungsten_send_diag, --args '--all'

Issues: CT-2150

MySQL clone can now be used as an option for recovery using tprovision.

Issues: CT-1417

tungsten_get_mysql_datadir can now return additional mysql database directories.

Issues: CT-1985

tprovision will now add a heartbeat after restore. This will ensure the replicator can be put back online when there is no load on the cluster.

Issues: CT-2005

The tprovision script will sleep for 5 seconds by default when using the rsync method after issuing a flush logs. The sleep value is configurable as a command line option --flush-after-sleep.

Issues: CT-2101

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 Documentation

Issues: CT-2164

Tungsten Connector now supports dual passwords, mirroring the MySQL v8.0.14+ functionality. When changing a user password, the previous password can be retained as long as needed in order to allow changing account passwords with no downtime.

Issues: CT-2127

Added a flag to avoid generating and sending EOF packets to client applications when CLIENT_DEPRECATE_EOF is not set on both client and mysql server sides. This fixes an issue with Go-MySQL-Driver and prepared statements.

When using Go MySQL Driver, flag --connector-generate-eof=false should be specified. Default is set to true for backwards compatibility.

Issues: CT-2177

Upgraded JGroups library to 4.2.22

Issues: CT-2011

There is a new datasource-group-id TPM option. In a single cluster the nodes with the same datasource-group-id will form a Distributed Datasource Group (DDG).

Issues: CT-2051

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

Issues: CT-2099

Added Prometheus exporter metrics for composite parent and sub-services.

Issues: CT-2121

Prometheus libraries have been upgraded from version 0.8.1 to 0.16.0

Issues: CT-2166

The ability to configure the Java Virtual Machine (JVM) settings for the manager has been made easier, by the use of the manager_java_settings.conf file. For more information see Section 8.7, “Adjusting JVM Settings for the Manager”

Issues: CT-2167

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

Issues: CT-2130

The tpm command now handles situations when the Manager process is not running.

Issues: CT-2103

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

Issues: CT-2104

The tungsten_find_orphaned command now handles some edge cases more gracefully.

Issues: CT-2107

The cctrl cluster topology validate command now checks, in a CAA setup, if the relay in the subservice is on the same host as the primary, and reports if there is a mismatch.

Issues: CT-2114

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 would produce errors if the local hostname were different from the hostname used in the Tungsten install (short vs long names).

Issues: CT-1363

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

Issues: CT-1901

tprovision would accept bogus options and not produce an error. This has now been fixed.

Issues: CT-2045

tprovision will now timeout if ssh is blocked from the target to the source host.

Issues: CT-2139

Using mysqldump for tprovision could incorrectly create a new SSL key pair.

Issues: CT-2142

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

Fixed NullPointerExceptions when reading packets from disconnected client connections.

Issues: CT-2132

Fixed a log4j configuration issue where the connector-audit.log and connector-api.log files that have been rotated will end up in cluster-home/bin/directory instead of tungsten-connector/log/.

Issues: CT-2137

Fixed an issue with topology validation when running tpm promote-connector on a witness host

Issues: CT-2161

Fixed an issue where a failover could hang in rare cases when security and Proxy mode are enabled. SSL connections to a failed data source could enter a deadlock and block failover for up to 15 minutes.

Issues: CT-2183, CT-2187

In a Composite Active/Active topology, issuing SHUN/DRAIN or WELCOME on a node in cctrl would only affect the node in the main cluster service. This action will now also be applied to the same node within the x_from_y sub-service.

Issues: CT-2145

A set of changes to improve cctrl responsiveness

Issues: CT-1795
