## What it is
Pogreb is an embedded key-value store written in pure Go, optimized for fast random lookups and infrequent bulk inserts in read-heavy workloads. It stores larger-than-memory data sets with low memory usage and is safe for concurrent use by multiple goroutines.

## Use cases
- embed a fast key-value store in a Go application
- store larger-than-memory datasets with low memory usage
- fast random lookups for read-heavy workloads
- simple local persistence without running a database server
- replace bolt/badger/goleveldb for point-lookup-heavy workloads

## When to choose
- your workload is dominated by point lookups rather than range scans
- you want a dependency-free, pure-Go embedded store
- you need low memory usage and larger-than-memory storage
- you need concurrent-safe access from multiple goroutines

## When to avoid
- you need range scans or ordered iteration
- you have write-heavy workloads with frequent bulk inserts
- you need fast crash recovery for very large databases
- you need multi-process access to the same database

## Facets
- artifact type: library
- maturity: stable
- function: database, caching
- domain: databases, developer-tools, backend
- platform: go, cross-platform
- tags: embedded-database, key-value-store, hash-table, read-heavy, wal, pure-go
