Hi
We intend to do a stream-static join where kafka is a streaming source and
RDBMS is a static source.
e.g. User activity data is coming in as a stream from Kafka source and we
need to pull User personal details from PostgreSQL.
Because PostgreSQL is a static source, the entire "User-Personal-D
able as a DataFrame and persist it in the
> memory. You may also need to repartition the DataFrame
