Sparkey is a simple constant key/value storage library written in C, essentially a read-only hash table on disk optimized for read-heavy systems with infrequent large bulk inserts. It ships as a C library (libsparkey) plus a command-line utility for inspecting and reading sparkey index/log files.

Use cases

  • store a large immutable key/value dataset on disk for fast random reads
  • periodically rebuild a lookup table with bulk writes and serve it read-only
  • embed a persistent hashtable in a C application without running a database server
  • inspect and read sparkey index/log files from the command line
  • serve rarely-updated reference data to high-throughput low-latency services

When to choose

  • your data is written in infrequent large bulk loads and read far more often than updated
  • you want a lightweight embedded key/value store with no server or network layer
  • you need many concurrent readers with low per-entry overhead and block compression

When to avoid

  • you need frequent incremental writes or multiple concurrent writers
  • you need a distributed or replicated key/value store
  • you need robustness against data corruption or a compacted data store
