Subject Performance of co-processor and observer while fetching data from other RS
Date Wed, 15 Jul 2015 06:17:37 GMT

REST APIs of my project make 2-3 calls to different tables in HBase. These
calls are taking 10s of milli seconds to finish.

I would like to know

1) If moving business logic to HBase co-processors and/or observer will
improve performance?

Idea is like to pass all the related information to HBase co-processors
and/or observer, co-processor will make those 2-3 calls to different HBase
tables and return result to the client.

2) I wonder if this approach will reduce time to finish or is it a bad

3) If co-processor running on one region server fetches data from other
region server then it will be same as tomcat server fetching that data from
HBase region server. Isn't it?
