Hi everybody: I have 18 nodes using cassandra2.1.2.Every node has 4 core, 32 GB RAM, 2T hard disk,OS is CentOS release 6.2 (Final).
I have follow the <Recommended production settings> to config my system.such as disable SWAP,unlimited mem lock... My heap size is: MAX_HEAP_SIZE="8G" MIN_HEAP_SIZE="8G" HEAP_NEWSIZE="2G" I use STCS,other config using default,using Datastax Java Driver 2.1.2. BatchStatment 100key commit per time. When I run my cluster and insert data from kafka (10000 keys/s) after 2 days,every node can't compact some there too many sstables. I try to use major compact to compact the sstables , it cost a long long time .Also the new sstables can't compat automatic. I trace the log , the CMS GC too often,almost 30 minute onetime. Could someone help me to solve this problem. -------------------------------------- 曹志富 手机：18611121927 邮箱：caozf.zh...@gmail.com 微博：http://weibo.com/boliza/
