Hi,
I'm testing around with cassandra fair a bit, using 2.1.2 which I know
has some major issues,but it is a test environment. After some bulk
loading, testing with incremental repairs and running out of heap once I
found that now I have a quit large number of sstables which are really
small:
<1k 0 0,0%
<10k 2780 76,8%
<100k 3392 93,7%
<1000k 3461 95,6%
<10000k 3471 95,9%
<100000k 3517 97,1%
<1000000k 3596 99,3%
all 3621 100,0%
76,8% of all sstables in this particular column familiy are smaller that
10kB, 93.7% are smaller then 100kB.
Just for my understanding - does that impact performance? And is there
any way to reduce the number of sstables? A full run of nodetool compact
is running for a really long time (more than 1day).
Thanks for any input,
Roland
