Hello all!

Would someone mind explaining to me how the spool\_size parameter affects the beats output?

Does it make it faster? Is it the amount of lines per transmission?

Thanks

The spooler collects lines from all prospectors and publishes them either if spool\_size is reached or idle\_timeout. Using spool\_size you can configure maximum batch size and idle\_timeout configures the maximum latency.
