Apache Pinot - A realtime distributed OLAP datastore
Role in this project:Back-end Developer
Back-end DeveloperContributions:3 releases, 341 reviews, 54 commits in 2 years 7 months
Contributions summary:Yupeng primarily focused on enhancing the Apache Pinot datastore's capabilities. Their contributions included adding multi-value support to the `SegmentDumpTool`, which involved modifying Java code within the `pinot-tools` module. They also introduced a message constraint for all instances in Helix to manage the total number of messages, which involved changes to `pinot-controller`. Furthermore, they added geo-spatial support and related functions for querying and data serialization in Apache Pinot.
