About Apache Pinot
Apache Pinot is a real time distributed OLAP datastore built to deliver scalable real time analytics at low latency. It lives in the Java ecosystem, is licensed under Apache 2.0, and was originally built by engineers at LinkedIn and Uber. The project ingests from batch data sources such as Hadoop HDFS, Amazon S3, Azure ADLS, and Google Cloud Storage, as well as from stream data sources such as Apache Kafka. It is designed to scale up and out with no upper bound, and its performance stays constant based on the size of the cluster and an expected query per second threshold.
