In today’s blogpost, we’re going to take a look at our upstream contribution to Apache HBase’s stochastic load balancer, based on our experience of running HBase clusters to support OVHcloud’s monitoring.

A code-level dive into HBase's MemStore, from the ConcurrentSkipListMap backing HBase 1.x to the in-memory compactions Accordion introduced in HBase 2.0.

An introduction to WarpScript, the stack-oriented language behind the Warp10 time series platform we ran at OVH's Metrics Data Platform to store and analyze sensor data.
