MDCB v2.0

2.0.5

Release date: 2023-01-31

Added

• Added a new configuration option (group_key_ttl) that specifies the group key TTL in seconds. This key is used to prevent a group of gateways from re-syncing when is not required. On login (GroupLogin call), if the key doesn’t exist then the sync process is triggered. If the key exists then the TTL just gets renewed. In case the cluster of gateways is down, the key will expire and get removed and if they connect again a sync process will be triggered. Default value: 180 seconds. Min value: 30 seconds.

Fixed

• Fixed an issue where gateways in the data plane couldn’t re-sync with MDCB (in the control plane) after their Redis (in the data plane) has been reset. The only way was to change the group_id. The fix means that MDCB can overcome this situation independently and there’s no need for the users to do anything (changing group_id or any other curing action). Check group_key_ttl for more details

2.0.4

Release date: 2022-12-06

Added

• Changes in the API definition introduced in Tyk Gateway 4.3
• Update to Go 1.16
• Update the embedded Pump to the latest (v1.7.0)

Fixed

• Fixed a minor security issue when logging Mongo URL

2.0.3

Release date: 2022-08-12

Fixed

• Fixed a bug when using MDCB with Tyk Gateway versions prior to 4.1 where an error could be reported when querying an API from a worker gateway.
• Fixed an incompatibility with MDCB logging format changes
• Fixed an issue where, with the MDCB Synchroniser disabled, all API resources were still pushed out to workers upon creation in the controller; the behaviour should be as it was pre-synchroniser.

2.0.2

Release date: 2022-08-12

Fixed

• Fixed a bug when using MDCB with Tyk Gateway versions prior to 4.1 where an error could be reported when querying an API from a worker gateway.

2.0.1

Release date: 2022-07-20

Added

• Updated MDCB to support Tyk Gateway v4.1
• Added a new configuration option (omit_analytics_index_creation) that supresses the creation of indexes in Mongo pumps (to match Pump 1.6)
• Added the option to configure MDCB certificates using environment variables.

Fixed

• Fixed a bug when using MDCB to transfer analytics to MongoDB, where the indexes Tyk created in the MongoDB did not correctly include a time stamp.

Changed

• Updated the pump embedded in MDCB to the latest version (Pump v1.6)

2.0.0

Release date: 2022-05-17

Added

SQL support

Since Tyk v4.0, the dashboard supports SQL engine natively. This means that Tyk has support for an SQL relational database to be used instead of the default MongoDB and lets users decide which DB type is the best for their usage. MDCB 2.0 introduces support for SQL to the multi data centre bridge, enabling MDCB orchestrated deployments using SQL databases. MDCB now uses embedded Tyk Mongo and SQL pumps to write analytics.

Fixed

• Fixed a security risk where API keys could be logged in plain text in MDCB logs.

Changed

• Improved the formatting of debug logs to align with the rest of the Tyk product suite.
• Hide innocent and unhelpful error messages related to the RPC connection that were spamming the logs
