Apache Pinot: Our Open Source is Built on Open Source

When building free open source software (FOSS) projects, maintainers can at times fall into the classic “not invented here (NIH)” syndrome. For various reasons they may choose to write their infrastructure code from the ground up. This can lead to reinvented wheels and present difficulties to keep the project maintained. Apache Pinot, on the other hand, is built on the foundations of multiple existing, already-successful open source projects. From Apache Zookeeper and Apache Helix for cluster management, to Apache Calcite for the underlying SQL parser and optimization techniques, Apache Lucene for text indexing and querying, as well as others, discover the architectural choices of other open source projects that underpin Pinot.
