StarRocks

StarRocks is a next-generation sub-second MPP (Massive Parallel Processing) database designed for real-time analytics. It combines the best features of OLAP and OLTP systems, allowing for both high-speed ingestion and complex analytical queries. StarRocks is particularly strong in multi-table joins, which are often a bottleneck in other real-time engines. Its vectorized execution engine and cost-based optimizer ensure that queries are executed efficiently.

It is a powerful alternative for organizations that need real-time performance but also require the flexibility of standard SQL for complex analytical workloads.
