Subject Re: How many task managers can Flink efficiently scale to?
Date Sun, 11 Aug 2019 10:17:18 GMT
Hi Chad,

In our cases, 1~2k TMs with up to ~10k TM slots are used in one job. In general, the CPU/memory
of Job Manager should be increased with more TMs.

use several thousand, so I'm curious how Flink compares in this regard.  Also, what aspects
of the system begin to deteriorate at higher scales?
