Glad to see people start trying on GreptimeDB. We're committed to building a fully open-source and cost-effective, unified time series database for metrics, logs, and events. To this point, it may still be too small to be included in the year database summary. But hope we'll grow fast in 2025 :)

This article shares key insights from a paper titled 'High-Performance Data Analysis using Object Storage on the Cloud', published by the team of Dominik Durner from the Technical University of Munich (TUM).

When developing our open-source cloud-native time-series analytical database GreptimeDB, we found this paper exceptionally beneficial. It primarily focuses on performing high-performance data analytics on object storage, with several conclusions providing clear direction for our engineering practices.

Thanks for your reply, I don‘t mean that the original SQL cannot do this kind of query, but using standard SQL to do such a query will be very complicated and inconsistent with user intuition.

What we have done is to provide an extended syntax of SQL so that users can more intuitively describe the query logic of aggregation based on time series data. But always open to discussions and feedback :)
