Samarth Jain commented on PHOENIX-4701:
---------------------------------------
I haven't closely looked at the original commit, [~jamestaylor]. But do you
think we can run into some kind of infinite loop by using the Phoenix API for
writing to the SYSTEM.LOG table? If so, we may need to do something similar
like what our tracing framework does where it makes sure writes to SYSTEM.TRACE
table do not generate traces themselves.

> If possible, the SYSTEM.LOG table would benefit greatly (3-5x perf gain)
> from being declared as immutable with a column encoding of 1 byte and a
> storage format of SINGLE_CELL_ARRAY_WITH_OFFSETS.
