QuestDB 8.1.0 - Parquet, smarter snapshots, improved SAMPLE BY, and more

QuestDB, an open-source time-series database, has introduced version 8.1.0, featuring several enhancements aimed at improving functionality and performance for high-demand workloads. The latest release includes read support for Apache Parquet, allowing users to integrate time-series data from Parquet files directly into QuestDB master tables and perform complex queries with ease. Additionally, improvements to the SAMPLE BY syntax enable users to define output ranges more precisely, enhancing data sampling and query results. Snapshot recovery has been simplified, now triggered by a trigger file in the QuestDB root directory, ensuring smoother recovery processes. Performance enhancements include reduced latency for ILP ingress, faster SQL transaction writing, and improved performance for various SQL operations, alongside multiple bug fixes addressing issues like incorrect query results and table suspension under memory pressure. As these features are rolled out, user feedback is encouraged to further refine and polish QuestDB's offerings.
