I have go through no. of documents/slides about HBase read/get operation... But I have lot of broken links and question to clear view about how hbase read operation happen...
Like.... Client Communicate to zookeeper and get region server where -ROOT- table region reside...(And this is in memory) Then getting region server location for .META table region (And this is in memory) Then location of region server where region of user table reside by checking start and end rowkey with given GET operation rowkey... then will search 1st in memstore.... if found then return data else BlockCache.... if not then BloomFilter if negative then return not found.... else read from hfile....(how i don't know.. please help me) Bloomfilter and BlockCache update and return data... Is this correct... Please suggest me some good document... Still i have doubt ... how BlockCache LRU works...
