Re: question on column families

No, Every column family has its own memstore. Each one is 128MB in your case. When flushing, the flusher will choose those memstore who satisfy certain conditions, so it is possible that not every column family(Store) will flush the memstore. Best Regards Allan Yang Antonio Si 于2018年11月14日周三 上午

Re: How does hbase find regionservers for scans

e markers for rows with prefix '28'. A major compaction will solve this case. But before finding out why, I think change this queries is the first thing need to be done. Best Regards Allan Yang 2017-07-15 11:14 GMT+08:00 Ted Yu <yuzhih...@gmail.com>: > I wonder what time unit you were using. &

Re: Regarding Connection Pooling

Connection is thread safe. You can use it across different threads. And requests made by different thread are handled in parallel no matter the keys are in the same region or not. 2017-06-12 20:44 GMT+08:00 Sachin Jain : > Hi, > > I was going through connections in

hbase.regionserver.thread.compaction.small = 30 Am I seeing it right? You used 30 threads for small compaction. That's too much. For heavy writes scenario, you used too much resource to do compactions. We also have OpenTSDB running on HBase in our company. IMHO, the conf should like this:
