Re: Client application single value KV Put high latency using multiple threads (pthread)


Lombardi, Johann
 

One roundtrip from client to leader and then one from leader to each other replica (i.e. one roundtrip for 2-way replication since the leader is a replica). Please check Liang’s paper (i.e. https://link.springer.com/chapter/10.1007/978-3-030-63393-6_22) for more information.

I am still interested in the type of network that you use. 40Gbps Ethernet with ofi+sockets provider? If so, you may want to try with ofi+tcp;ofi_rxm too.

 

Cheers,

Johann

Hi Johann,

Thanks for the tips.  Could you tell me how many roundtrip RPCs are involved from the client's perspective?  Also, how many RPCs are involved between the leader and the replica?

Thanks
Ping
