We finally benchmarked InfluxDB 3 OSS Core (Alpha)

QuestDB, an open-source time-series database known for its high ingestion throughput and low latency, was compared to InfluxDB 3.0 Core Alpha in a performance benchmark. The test revealed that QuestDB significantly outperformed InfluxDB, with ingestion speeds approximately 5.5 times faster and much quicker query response times. InfluxDB 3.0 Core, described as a "recent-data engine," is still in its Alpha stage and not production-ready, exhibiting limitations such as a 72-hour query time span, data loss under concurrent loads, and performance issues with ingestion. Although it introduces a modernized engine with SQL support, the current version falls short in reliability and efficiency compared to QuestDB, which shows robust performance and compatibility with the Influx Line Protocol. The evaluation suggests that InfluxDB's open-source version may serve more as a precursor to its commercial cloud offering, prompting users seeking a fully capable open-source solution to consider alternatives like QuestDB.
