is a distributed, fault-tolerant observability pipeline.
It's fast, memory-efficient, and capable of aggregating global metrics.
It's designed to be:
Memory-efficient: Perform aggregation in constant space with HyperLogLog and t-digests.
Run host-local instances, but also get global aggregate metrics.
Pluggable: Archive data in S3, Redshift, or a custom backend.
Parallelized: Scale metrics processing with a configurable worker pool.
