Hi, I am trying to upgrade the JAVA SDK from 1.x to 2.5.8.
But I found that the performance on batch operation is very bad on 2.5.8.
I’m using Observable for 2.5.8 and asyncGetBulk() for 1.x.
Using the same stress test program, the CPU loading and response time on using 2.5.8 is very much higher than the old one.
I’m batch getting ~2000 keys per request, with 4 requests per second. Using 1.x passed with success, while 2.5.8 starts to fail on around 500 requests.
May I know how can I keep the performance as asyncGetBulk()? As this function has been removed in 2.5.8.
Thanks a lot!
