1.	Explain The Execution Model Of Logstash?
Answer» The Logstash event processing pipeline coordinates the EXECUTION of inputs, filters, and outputs. Each input stage in the Logstash pipeline RUNS in its own thread. Inputs write events to a CENTRAL queue that is either in memory (default) or on disk. Each pipeline WORKER thread TAKES a batch of events off this queue, runs the batch of events through the configured filters, and then runs the filtered events through any outputs.
