Hi all,

We are using Hector and ofter we see lots of timeout exception in the log, I know that the hector can failover to other node, but I want to reduce the number of timeouts.

any hector parameter I should change to reduce this error?

also, on the server side, any kind of tunning need to do for the timeout?
 

Thanks in advance.
