Aleksey Yeschenko commented on CASSANDRA-10024:
-----------------------------------------------
Have you measured it having any effect?
Under normal operation, your should almost never have any batchlog entries
hitting disk (except as commit log entries) - memtable flushing has special
cased code for just that.
And in 3.0 even less so, with explicit compaction at the end thrown out with
CASSANDRA-7237, and no more full scanning.
> Skip page cache for batchLog

> We should skip the page cache for batch log. There could be more internal
> tables where this might make sense.
