Pinot shares similar features with comparable OLAP datastores, such as [[Apache Druid]].<ref>{{cite book |last1=Ordonez |first1=Carlos |last2=Song |first2=Il-Yeol |last3=Anderst-Kotsis |first3=Gabriele |last4=Tjoa |first4=A.

Pinot supports pluggable [[Database index|indexing technologies]] - Sorted Index, [[Bitmap Index]], [[Inverted index|Inverted Index]], Star-Tree Index, and Range Index, which are what primarily differentiates Pinot from other OLAP datastores.

Pinot supports near real-time ingestion from streams such as [[Apache Kafka|Kafka]], [[AWS]] Kinesis and [[Batch processing|batch]] ingestion from sources such as [[Hadoop]], [[Amazon S3|S3]], [[Microsoft Azure|Azure]], [[Google Cloud Storage|GCS]]. Like mostly, allmost other [[Online analytical processing|OLAP]] datastores and [[data warehousing]] solutions, Pinot supports a [[SQL]]-like query language that supports selection, aggregation, filtering, group by, order by, distinct queries on data.
