hi all:
I wonder if I increase the size of the Region, will it make bad
effect on the latency of the read operateion?
The default size of the region is 10G I saw from the official guide.
I configured 100G per region on my cluster.
Because my Regionserver Hardware parameters is :
RAM: 128G
CPU: 24 core
Disk: 3T * 10 total:30T
Regionserver disk capacity is 30T, if I use the default
configuration(10G per region), this will result too many regions(about
30T/3/10G=1000) on one region server.
But when I retrieve the 100G storefile, it will take a longer
time(about 50ms,sometimes 100ms+) to return the result than a storefile which
is 200M(below 10ms) dose.
I wonder to know whether is the size of the region result in the
difference?
If 100G is too big for a region, which size will be suitful for my
region server?
