--------------------------------------

Hi [~akalashnikov],
How are things going with the testings? Do we have any updates?

> 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.
