Yes you are right Anishek. If you write with LOCAL_ONE, values will be the same.


Re: Ops Centre Read Requests / TBL: Local Read Requests

Looks like (1) -- is analogous to client read requests, so if i do a
request with LOCAL_QUORUM consistency level then (2) would be higher since
the coordinator would send two requests out for every single read request
it receives, is there any other possibility for the above behaviour ?

Ops Centre Read Requests / TBL: Local Read Requests

2016-02-15 Thread Anishek Agarwal
Hello,

I have installed Ops center 5.2.3 along with agents on three cassandra
nodes in my test cluster version 2.0.15. This has two tables in one
keyspace. I have a program that is reading values only from one of the
tables(table1) with in a keyspace.

I am looking at two graphs

   - Read Requests across Cluster  -- (1)
   - TBL: Local Read across Cluster for table1  -- (2)

I find that the (2) is having higher numbers than (1) almost twice as much,
is there something i am measuring wrong? i would think (1) would always be
higher than (2) .

table1 has

   - has a composite partition key (long,long)
   - has a single clustering key (text)


thanks
