Hi,
Recently In my test Cluster I faced a outrageous GC activity which made
the Node unreachable inside the cluster itself.
Scenario :
In a Partition of 5Million rows we read first 500 (by giving the starting
range) and delete the same 500 again.The same has been done recursively by
changing the Start range alone. Initially I didn't see any difference in the
query performance ( upto 50,000) but later I observed a significant increase in
performance when reached about a 3.3Million the read request failed and the
node went unreachable. After analysing my GC logs it is clear that 99% of my
old-memory space is occupied and there are no more space for allocation it
caused the machine stall.
here my is doubt is that does all the deleted 3.3Million row will be
loaded in my on-heap memory? if not what will be object that occupying those
memory ?.
PS : I am using C* 2.1.13 in cluster.
