## What it is
Diskv is a simple, persistent key-value store written in Go that stores arbitrary data on the filesystem by key. It layers performance-enhancing abstractions like caching and indexing on top of a conceptually simple disk-backed design.

## Use cases
- persist key-value data to disk in a Go application
- store arbitrary binary blobs keyed by string
- embed a simple disk-backed database without a server
- cache data on the filesystem with an in-memory read cache
- organize data files on disk via a custom key-to-path transform

## When to choose
- you need a dependency-free, embedded persistent key-value store in Go
- your data should remain readable as flat files on disk
- you want simple API semantics like Read/Write/Erase without running a database server

## When to avoid
- you need queries, transactions, or rich data types beyond key-value
- you need concurrent multi-process access or network access to the store
- you need an actively developed project with recent releases

## Facets
- artifact type: library
- maturity: maintenance
- function: database, caching, file-system
- domain: databases, developer-tools
- platform: go, cross-platform
- tags: key-value-store, disk-backed, embedded-database, persistence
