What is the best way to get the total row count?


I tried following things,

a>     Count 'tablename' in shell prompt: Helpful, only with very less
number of records.

b>     Runing RowCounter Job: It took almost 8hr to get row count of 2TB
data in 3node cluster (16 core system, 48GB RAM)

c>   Using AggregationClient: Disk IO is very high (System wait is 65-70%,
Load factor is almost 110), this makes server to non responsive and makes
the clients to go down (Due to RPCTimeOut Exceptions).

Thanks & Regards,

Gopinathan A
