Hi, This is my first email to this list, hello everyone!
I have a question regarding the confluent version dependency that beam, or more specifically kafka io extension, is currently using. Tl;dr is that I'd like to update the confluent library version to something more recent, and was wondering if I could just open a PR and maybe create an issue for that in github. More context: Right now the confluent dependency version is set at 5.3.2, which is quite old (5 years or so) - one feature that we recently discovered is missing in this version is the support for configuring schema registry client's ssl configuration - according to the (current) docs ( https://docs.confluent.io/platform/current/installation/configuration/consumer-configs.html) there's a whole bunch of configuration keys starting with a "ssl." prefix that dictate how a schema registry client might access the schema registry - the issue is that support for those config keys on the client side had only been added starting from version 5.4.0 IIUC ( https://github.com/confluentinc/schema-registry/pull/957). Without it, the ssl has to be configured using standard JVM classes such as SSLContext or HttpsURLConnection, which on top of being slightly unintuitive is also undocumented - therefore I'd like to suggest updating the confluent libs version to something more recent. I have already managed to update them to a version as high as 7.6.0 (which is the most recent one, from what I gather), and successfully run tests and build the extension - apart from updating the confluent library version itself I had to additionally update the avro code generation plugin as well as the avro dependency. Let me know what you think. Thanks, Maciej
