The connector automatically syncs data additions, updates, and deletions from Delta Lake Gold tables into Pinot, supporting low-latency, high-throughput user-facing analytics while Delta Lake continues to handle bulk data processing and AI/ML workloads. Column Mapping is not yet supported, requiring backfilling for schema changes. The piece also recaps recent Delta Lake features like UniForm, Deletion Vectors, and Liquid Clustering. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What does the new StarTree connector for Delta Lake use to integrate with Apache Pinot? It is built on the Delta Kernel library, which provides stable APIs so developers do not need to manage Delta Lake's log files and protocol details directly. The connector automatically syncs additions, updates, and deletions from Delta Lake Gold tables into Apache Pinot, and StarTree's backfilling feature handles schema evolution, though Column Mapping support is not yet included. _Teams wiring Delta Lake into real-time serving layers can track connector updates like this on daily.dev._ ### Why would I use Apache Pinot alongside Delta Lake instead of just querying Delta Lake directly? Delta Lake excels at large-scale data processing and ad-hoc analytics but struggles to deliver the extremely low query latency and high queries-per-second that user-facing analytics demand. Apache Pinot, via StarTree, uses columnar storage, pluggable indexing, and distributed processing to serve tens of thousands of users with low-latency queries, while Delta Lake continues handling AI/ML and exploratory workloads. _Engineers choosing between processing and serving layers can follow comparisons like this on daily.dev._ ## Similar posts on daily.dev -
