* setting the batch interval _to 1_

Hello Swapnil,
setting the batch interval should be pretty much equivalent to having
a streaming jdbc connector.

Hi Stephen/Chesnay,
I have used JDBCOutputFormat from batch connectors for my streaming use
case as I didn't find jdbc connector from streaming connectors.
If it is not there, may we have jdbc connector for streaming use cases?
Thanks,
Swapnil

The JDBCOutputFormat writes records in batches, that's what he is
referring to.

Hi!
I am not sure I understand what you want to do, but here are some
comments:
- There is no "batching" in Flink's streaming API, not sure
what you
are
referring to in with the "last batch"
- JDBC connections are not closed between windows, they remain
open as
long as the operator is open.
Thanks,
Stephan

Hi Team,
Can we handle one case in connector JDBCOutputFormat to update
last batch
(might be batch count is less than batch interval) without closing
jdbc
connection?
During use case of my streaming project, I am updating jdbc sink
(mysql
db)
after every window.
Case : Say I have 450 queries to be updated in mysql with batch
interval
100.
400 queries are executed in 4 batches (4 x 100).
Last 50 queries go into pending state in batch to be executed &
wait for
next 50 queries from next window.
If window is of size 5 minutes, then it will take next 4-5 minutes to
reflect last 50 queries in mysql.
Can we have functionality in JDBCOuputFormat to flush last batch
to jdbc
sink persisting same db connection.?
Thanks,
Swapnil
