Actually there is no delete right now. Only inserts.
I use twcs and not much compaction occurs.
It just miscalculates sstable sizes.

On restart, it performs major compaction which can reduce the load on your node 
by removing stale data.
Try configuring compaction in you conf to perform minor compaction i.e. 
compactions at a regular interval.

Re: nodetool status high load info

2017-04-12 Thread Bhuvan Rawal 
Try nodetool tpstats - it can lead you to where your threads are stuck.
There could be various reasons for load factor to go high like disk/cpu
getting choked, you'll probably need to check dstat & iostat output along
with Cassandra Threadpool stats to get a decent idea.

Hello,

Nodetool status shows much more than actual data size.
When I restart node, it shows normal a while and increase load in time.
Where should I look?
