Camel SEDA and JDBC

[Ravi Nallappan <ra...@gmail.com>]

Hi,

I have created a route with seda consumer (concurrentConsumers=20). And I am using camel jdbc to query a database (mysql) based on key provided in body.

For this, can I expect there will be 20 jdbc sessions created and queried in parallel?

When send data thru this route, I do able to see "Threads_running" up to 10 (show global status like "%thread%"). And reducing  concurrentConsumers to 1 does bring "Threads_running" to 1. But for some reason, does not go beyond 10 - before I ponder on mysql settings, I would like to confirm my expectation that parallel queries should be same as number of concurrentConsumers that I set?

Thanks and regards,
Ravi Nallappan

Only if there is enough messages in the  queue for all seda consumers
to process concurrently.
