public class PinotBufferIndexInput
extends org.apache.lucene.store.IndexInput

PinotBufferIndexInput is a wrapper around PinotDataBuffer implementing IndexInput apis. It acts as a bridge between lucene FST reader library and PinotDataBuffer, it lets FST index load into PinotDataBuffer and helps in utilizing FST reader (org.apache.lucene.util.fst.FST).
