Hi, I am using hbase 0.94.11 and i feel a bit confuse when looking at the log file below:
13/09/24 13:11:00 INFO regionserver.Store: Flushed , sequenceid=687077, memsize= 122.1m, into tmp file hdfs://192.168.123.123:54310/hbase/usertable/b19289cf9b1400 c6daddc347337bac03/.tmp/13f0d91efe784372a796585a6c1e05d3 13/09/24 13:11:00 INFO regionserver.Store: Added hdfs://192.168.123.123:54310/hba se/usertable/b19289cf9b1400c6daddc347337bac03/family/13f0d91efe784372a796585a6c1 e05d3, entries=432620, sequenceid=687077, filesize=64.4m 13/09/24 13:11:00 INFO regionserver.HRegion: Finished memstore flush of ~128.2m/ 134402240, currentsize=48.0m/50366240 for region usertable,user4\xB4\xB0,1379998 895119.b19289cf9b1400c6daddc347337bac03. in 1163ms, sequenceid=687077, compactio n requested=false It seems like it will first flush into a tmp file and the memsize is 122.1m, but when it finally added, the size is 64.4m. Lastly, there are 2 more parameters which is 128.2m and 48.0m for currentsize. I never specify hbase.regionserver.codecs preperty in my hbase-site.xml file, so is the size difference still because of compression?
