Hello!

We plan to use debezium to sync the data from postgres to kafka and want to use the wal2json_streaming plugin according to official documents.

However, we can not find any infomation how to install this plugin except wal2json and decoderbufs.

Whether we just only need to install wal2json plugin or not.

Thanks!

Hi,

I strongly recommend to use pgoutput (coming with Postgres itself since version 10) instead of wal2json. We are planning to drop wal2json support in one of the upcoming releases. If you still want to use it for the time being, the plugin is just named "wal2json", there's different modes for using it, the streaming mode being one of them.
