[GitHub] [pinot] ankitsultana opened a new issue, #8951: Colocated Join Support in Pinot
ankitsultana opened a new issue, #8951:
URL: https://github.com/apache/pinot/issues/8951
Native Join support has just recently been added to Pinot via the Multi-Stage Execution Engine Support. For some high-throughput join use-cases, we should be able to improve the performance quite a bit by avoiding the shuffle step. This can be done by ensuring that data for the same partition lies on the same servers.
We have started looking into Colocated Joins and have broken it down into two parts:
1. Supporting co-location of data (via a new concept called Table Groups).
2. Adding support for Co-located join in the existing join framework.
We also wrote a design doc for the first part: https://docs.google.com/document/d/1HWkRmjUxLBnkKETw21GJ--yQdiFa9hEE4v6Y68nNWx4/edit#heading=h.xhb8dmu7bi7k
Would be great to get the community's feedback.
