## What it is
Beringei is a high-performance, in-memory time series storage engine based on Facebook's Gorilla paper, usable as an embedded library or as a sharded service with a reference HTTP service for Grafana integration. It features delta-of-delta streaming compression and disk-backed persistence.

## Use cases
- store time series metrics for system monitoring
- build a custom performance monitoring backend
- compress time series data efficiently
- serve metrics queries to Grafana
- embed a fast time series store in a C++ application

## When to choose
- you need extremely fast in-memory time series queries in C++
- you want to study or build on the Gorilla compression approach
- you need a self-hosted metrics store with Grafana support

## When to avoid
- you need a maintained, production-ready time series database (repo is archived)
- you want broad platform support beyond Ubuntu Linux
- you prefer batteries-included monitoring solutions like Prometheus or InfluxDB

## Facets
- artifact type: library
- maturity: abandoned
- function: database, monitoring, compression, http-server, caching
- domain: databases, monitoring, time-series, performance, developer-tools
- platform: cpp, self-hosted
