Bugfixes

This is a complete list of the merged pull requests, including the fixed bugs.

Improve performance of JWT validations by caching jwt validator

For some users of Ditto, the performance of JWT validations was dramatically bad. This bugfix caches the creation of the JWT parser based on the public key and should dramatically improve the performance of HTTP requests using JWT.

Improve Kafka consumer performance

This bugfix should reduce the CPU load in the connectivity service and number of requests/second to the Kafka broker by increasing fetch.max.wait.ms to 5 seconds.
It should also reduce the consumer lag due to a lack of threads when there are a lot of consumers running.

Keep order of json elements in connection model in set structures

Previously, the JSON element order e.g. in arrays in a managed connection could be mixed up, e.g. from creation to persistence. This has been fixed by maintaining the JSON element order in the connection model.

Updated to Pekko HTTP 10.2.7 due to critical reported CVE

The for Ditto's HTTP API used library contained a critical security issue CVE-2021-42697 which has been resolved in Pekko HTTP 10.2.7
