What does pset and reuse mean in splunkd.logs

[dexterp]

Given this search for the TcpOutputProc

index=_internal source=*splunkd.log component=TcpOutputProc | fields _raw | head 5

What do the fields pset and reuse stand for?

Hi @dexterp,

"pset" means pipelineset on indexers. Indexers use default single pipeline set as default . If your indexers underutilized, in order to increase indexing throughput capacity you can increase this setting. Your logs show that your system uses single pipeline set. This setting can be used on forwarders and indexers or both.

You can find more detail in below document;

I thought it might be pipeline set, I just wanted to confirm it with Splunk.
