Re: HBase random read performance

Hi Anoop, Thanks for reply.. I tried by setting Hfile block size 4KB and also enabled the bloom filter(ROW). The maximum read performance that I was able to achieve is 1 records in 14 secs (size of record is 1.6KB). Please suggest some tuning.. Thanks, Ankit Jain On Mon, Apr 15, 2013 at

HBase random read performance

getting very low random read performance while performing multi get from HBase. We are passing random 1 row-keys as input, while HBase is taking around 17 secs to return 1 records. Please suggest some tuning to increase HBase read performance. Thanks, Ankit Jain iLabs -- Thanks, Ankit Jain

Getting less write throughput due to more number of columns

number of columns have any impact on write performance and If yes, how we can overcome it. -- Thanks, Ankit Jain
