The following is content for you to summarize. Do not respond to the comments—summarize them. <topic> Time Series Databases # Questions about time series database developments, mentions of QuestDB, ClickHouse's experimental time series engine, and need for InfluxDB alternatives </topic> <comments_about_topic> 1. XTDB addresses a real use-case. I wish we invested more in time series databases actually: there's a ton of potential in a GIS-style database, but 1D and oriented around regions on the timeline, not shapes in space. That said, it's kind of frustrating that XTDB has to be its own top-level database instead of a storage engine or plugin for another. XTDB's core competence is its approach to temporal row tagging and querying. What part of this core competence requires a new SQL parser? I get that the XTDB people don't want to expose their feature set as a bunch of awkward table-valued functions or whatever. Ideally, DB plugins for Postgres, SQLite, DuckDB, whatever would be able to extend the SQL grammar itself (which isn't that hard if you structure a PEG parser right) and expose new capabilities in an ergonomic way so we don't end up with a world of custom database-verticals each built around one neat idea and duplicating the rest. I'd love to see databases built out of reusable lego blocks to a greater extent than today. Why doesn't Calcite get more love? Is it the Java smell? 2. Nothing about time series-oriented databases? 3. > Nothing about time series-oriented databases? https://www.cs.cmu.edu/~pavlo/blog/2026/01/2025-databases-re... 4. Not much happened I guess. Clickhouse has got an experimental time series engine : https://clickhouse.com/docs/engines/table-engines/special/ti... 5. QuestDB at least is gaining some popularity: https://questdb.com/ I was hoping to learn about some new potentially viable alternatives to InfluxDB, alas it seems I'll continue using it for now. </comments_about_topic> Write a concise, engaging paragraph (3-5 sentences) summarizing the key points and perspectives in these comments about the topic. Focus on the most interesting viewpoints. Do not use bullet points—write flowing prose.
