Why HN links it
HN readers link StarTree's resources for comparisons of real-time analytics databases, such as Apache Pinot, Druid and ClickHouse, for low-latency queries and streaming data.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
StarTree, powered by Apache Pinot, is the real-time analytics query engine built for revenue-critical workloads: customer-facing analytics, observability, personalization, and agent-driven decisions. It queries streaming data alongside open table formats including Apache Iceberg and Delta Lake, deli

HN discussionYikes! 30 Sep cut off? That's not a lot of lead time, given the amount of work database systems require to data model, benchmark and migrate. My apologies if this seems inappropriate but given the urgency, my employer, StarTree, has a free tier if anyone needs to try out alternate solutions. https://startree.ai/saas-signup I understand Rockset-to-StarTree (Apache Pinot) is not a 1:1 drop-in replacement. But hopefull…

HN discussionJOINs are a non-trivial problem with data in the terabyte-to-petabyte range. Apache Pinot had to re-architect itself with a multi-stage query engine in order to handle native query-time JOINs. There was a separate blog released today that dealt with that specifically: https://startree.ai/blog/query-time-joins-in-apache-pinot-1-... [Edit: if users just naively throw query-time JOINs at a problem, they might not get r…

HN discussionThat's a great question. A bit of history. Here's more on Pinot, back when it was invented at LinkedIn, before it was ASF-incubated as "Apache Pinot." LinkedIn originally had been using traditional OLTP systems to power the "Who Viewed My Profile" app; they just simply hit the wall. So LinkedIn looked at other analytics databases at the time. Most just couldn't handle a large number of QPS — which, as a social media…

HN discussionYou need to look at use-case alignment as well as performance. Apache Pinot, Druid and Clickhouse are designed for low-latency analytical queries at high concurrency with continuous ingestion. Pinot is popular because of it's native integration with streaming systems like Kafka, varied indexing, and it's ability to scale efficiently. They're widely used in observability and user-facing analytics – which are how “rea…

HN discussionNice break down. I just came across a similar breakdown of Apache Pinot vs Clickhouse vs Druid at https://startree.ai/resources/a-tale-of-three-real-time-olap... We're experimenting with Pinot for it's ability to do low latency query on streaming data at high concurrency, tight integration with Kafka, and the ease of which it handles upserts.
