Time-Series Databases: How They Store Billions of Points in a Couple of Bytes Each
Traditional B-tree databases collapse under append-only telemetry. This is a deep dive into how TSDBs ingest millions of points per second — WAL, MemTables, LSM compaction, and the Gorilla compression that squeezes a 16-byte data point down to ~1.37 bytes. Covers cardinality, data modeling, and how to pick between Prometheus, VictoriaMetrics, TimescaleDB, and InfluxDB.
