Hi All in this great project,
I have an HBase cluster of four nodes, I use Phoenix to access HBase, but I
do not know why its too much slow to execute SELECT count(*) for table
contains 5 million records it takes 8 seconds.
Below is the explain for may select statement
CLIENT 6-CHUNK 9531695 ROWS 629145639 BYTES PARALLEL 1-WAY FULL SCAN OVER
TABLE* |*
*| * SERVER FILTER BY FIRST KEY ONLY
* |*
*| * SERVER AGGREGATE INTO SINGLE ROW
Anyone can help.
Many Thanks
