Hi Flink Users, I use Flink SQL to ETL Kafka event data into tables we use for analysis, and I'm currently trying to use it to basically extract a few fields out of some JSON, but leave the original blob in a subdocument using the elasticsearch connector.
I see that there is `ROW` and `MAP` but I don't see any data types for unstructured JSON blobs. This would be really useful for both `jsonb` columns in Postgres and subdocuments in Elasticsearch. Has anyone found a good solution for this? Thanks, Tim
