The article explains vmselect’s core functionalities: concurrent request processing, query parsing and validation, data fetching and merging from vmstorage nodes, and memory-efficient result caching.
Say hello at booth #313 for SCaLE 22x in Pasadena, meet our team, and find out about the latest updates on our new VictoriaLogs solution, the latest VictoriaMetrics updates and more.
Whether you’re just discovering VictoriaLogs or have been using it for a while, this post will walk you through the recent enhancements and give you a sneak peek at the much anticipated cluster version that’s on the horizon.
When evaluating, instant vectors provide current snapshots, while range vectors give you multiple values over a period of time. But how do they work?
Metrics come in different types: counters that only increase, gauges that fluctuate, histograms that show value distributions, and summaries that pre-calculate statistics.
When we ended 2024 with continued growth (300+%) both in terms of open source adoption and enterprise business we thought: We’re going to need some more help in 2025!
FOSDEM (Free and Open Source Software Developers’ European Meeting) is a huge, free, gathering for open-source software enthusiasts that happens every February in Brussels, Belgium. It’s a non-profit event put together by the community, and it’s one of the biggest of its kind. See more in our recap!
When vmselect asks vmstorage for data, there’s actually quite a bit happening behind the scenes. This article breaks down the process of how vmstorage locates and retrieves your metrics, from finding the right TSIDs to sending back the actual data points.
IndexDB acts as vmstorage’s memory - it remembers which numbers (TSIDs) belong to which metrics, making sure your queries get answered fast. This article walks through how this system works, from the way it organizes data to how it keeps track of millions of timeseries.
