Btw, I am keen to contribute especially to avro stuff as we have use cases within our org. I tried the plugin creation workshop to get a feel of what is involved in building a plugin. I found
this template quite useful. As a follow on to the workshop, I played with it little bit making use of ANTLR to auto generate parsers for
this grammar. Then added bit of logic on top of that to create interaction with matching rules for message payload using avro. This is all to get a feel of what is involved and didn’t want to go any further than that. This all looks interesting and I am keen to contribute either to the existing avro plugin or continue creating a version of it using golang if that is the preferred language.
