This is true.
So, if I can set env.java.opts: "-Xmx102g" in flink-conf.yaml, I am

Hi Xintong,
Just to be clear. I haven't set any -Xmx -i will check our scripts again.
Assuming no -Xmx is set, the doc above says 1/4 of physical memory i.e 29GB
will be used.
So, if I can set env.java.opts: "-Xmx102g" in flink-conf.yaml, I am
assuming the heap max of 102Gb will be used in the N/w
Flink should have calculated the heap size and set the -Xms, according to
the equations I mentioned. So if you haven't set an customized -Xmx that
overwrites this, it should not use the default 1.4 of physical memory.

Thx, Xintong for a great answer. Much appreciated.

Hi Vijay,
The memory configurations in Flink 1.9 and previous versions are indeed
complicated and confusing. That is why we made significant changes to it in
Flink 1.10. If possible, I would suggest upgrading to Flink 1.10, or the
upcoming Flink 1.11 which is very likely to be released in this mon
