As a developer tools analyst, I've compared Project A, Apache Doris, and Project B, Trino, focusing on momentum, community size, and apparent use cases for senior engineers. In terms of momentum, both projects exhibit strong growth, though Apache Doris slightly outpaces Trino. With 15,154 total stars and 127 stars added in the last 30 days, Apache Doris demonstrates a steady increase in popularity. Trino, with 12,691 total stars and 118 new stars in the same period, shows similar yet slightly less accelerated growth. Regarding community size, Apache Doris appears to have a larger following, indicated by its higher total star count. However, the difference in new stars over the last 30 days is relatively minor (9%), suggesting comparable community engagement rates for both projects. Use cases diverge notably. Apache Doris is positioned as a unified analytics database, implying suitability for a broad range of analytics workloads, from operational to analytical, potentially appealing to teams seeking an all-in-one solution. Trino, as a distributed SQL query engine, is optimized for big data scenarios, likely attracting users focused on federated queries across disparate data sources or those already invested in the Presto ecosystem (given its origins as PrestoSQL). Senior engineers evaluating these projects should consider whether they need a comprehensive analytics database (Apache Doris) or a specialized big data query engine (Trino).
