How to configure kafka cluster for batch processing -


i trying provide number of new rows db(consumer) using kafka connect. i've configured source config file as

this how source.properties looks:

 name=source-postgres  connector.class=io.confluent.connect.jdbc.jdbcsourceconnector  tasks.max=1  batch.max.rows = 10  connection.url=jdbc:postgresql://<url>/postgres?user=postgres&password=post  mode=timestamp+incrementing  timestamp.column.name=updated_at  incrementing.column.name=id  topic.prefix=postgres_

this content of sink property file

name=dbx-sink batch.size=5 connector.class=io.confluent.connect.jdbc.jdbcsinkconnector tasks.max=1  # topics consume - required sink connectors 1 topics=postgres_users  # configuration specific jdbc sink connector. # want connect sqlite database stored in file test.db , auto-create tables. connection.url=jdbc:postgresql://<url>:35000/postgres?user=dba&password=nopasswd auto.create=true

but doesn't have effect, whenever new row available it's getting inserted db (consumer). so, added config parameter sink batch.size=10. has no effect.

when starting connect-standalone.sh script can see batch.max.rows = 10 on console.

what doing wrong or how fix it?

batch.max.rows send 10 rows per batch; won't limit number of rows sent in total.
