It is easy to implement RAID1-like replication in VictoriaMetrics: just set up independent VictoriaMetrics instances (single-node or clusters) and replicate all the incoming data simultaneously to these instances. This can be done either vi

It is more like RAID0. VictoriaMetrics shards time series among available vmstorage nodes. I.e. each vmstorage node contains a part of data stored in the cluster. This is usually named shared nothing architecture [1]. As for data replicatio

Ingestion rate of 1K metrics per second can be handled by any solution on low-end hardware. I believe even ancient Raspberry PI would feel comfortable with such a load :) VictoriaMetrics scales to 50M+ metrics per second on a single server

VictoriaMetrics author here. I like the post, since it is cleanly written and it isn't biased to certain solution. I'd recommend readers trying all the mentioned solutions - Thanos, Cortex, M3DB and VictoriaMetrics and then choosi

Btw, it should be easy adding fsync to ClickHouse. For instance VictoriaMetrics uses similar file format as ClickHouse, and it issues proper fsyncs at least every second, so it may lose only the last second of data on unclean shutdown such

Thanks for the warm response! > Honestly, @valyala should just create a metrics collector and then I wouldn't have to deal with the "we know better" attitude from some Prometheus contributors We didn't want going this

To be fair, VictoriaMetrics also contributes to Prometheus ecosystem by providing open source cost-effective remote storage for Prometheus, which is easy to setup and operate. Additional contributions to Prometheus ecosystem include: * Fili

Yet another case of "fair" competition from Prometheus and Thanos devs [1]: * Prometheus users proposed extending `/api/v1/label/.../values` API [2], which has been already implemented in VictoriaMetrics.

I'm trying hard to write polite comments, which could help users finding the solution for their issues. My comments could be harsh only in response to misleading posts about VictoriaMetrics [1]. [1] https://www.robustpercept

Another case of unfair competition is the article [1] published by Prometheus author, where he claims VictoriaMetrics doesn't compress random data well. I hope Prometheus author knows information theory [2] and was aware that random da

An additional case of unfair competition was at PromCon 2019. There was a talk named `Remote storage wars` from Adidas at the conference [1]. Various remote storage solutions for Prometheus were compared in the talk for use cases specific t

Are Prometheus and Thanos developers against fair competition?

There is VictoriaMetrics, which is also written in Go and shows much higher performance numbers than InfluxDB, especially on high cardinality data. See [1], [2] and [3]. [1] https://medium.com/@valyala/measuring-vertica

Another viable player that took the path similar to M3DB is VictoriaMetrics [1]. This allowed implementing various features [2] and optimizations [3] without the need to negotiate their integration into upstream Prometheus. Such negotiation

This is great news! We at VictoriaMetrics [1] are happy that TimescaleDB eventually addressed high disk usage issue and implemented type-aware column-based compression. This should improve its' position and performance in TSBS benchmar
