Description

Test different jobs:

• a job with static throughput (must work for successful MVP)

• a job with gracefully varying load (sinus shape load?) (should work for successful MVP)

• a job with erratic load (emulating evil window operator firing) (would be nice to work for MVP)

Test on cluster all jobs and check if/how buffer size adjustment is not erratic.

Verify our final goals:

• that aligned checkpoint time in back pressured jobs is reduced to sane values (roughly numberOfExchanges * configuredBufferedDataTime * 2)

• check if our changes affected the throughput or not.
