Vaultaire: a Ceph based, immutable TSDB - AWS Managed Services by Anchor
Anchor has been working on building a massively scalable data vault for metrics data. One of our engineers has written a blog post about what worked – and what didn’t – in the first version, and what we’ve learned from it. Motivation Here at Anchor we are reworking the way we store systems metrics. This has inspired the development of a new immutable and lossless Time Series Database (TSDB), a concept for which we have coined the term “a data vault for metrics”. We currently use Round-Robin Databases (RRD) to store metrics; unfortunately, aside from the simplicity and constrained size of RRDs, they don’t have much going for them. In particular, RRDtool: by design, cannot import historical data; sacrifices data over time to save space; and requires one file per...
