vsdb

vsdb is a 'std-collection-like' database.

This is a simplified version of the original vsdb, retaining only the most practical and stable parts.

To view the change log check here.

Highlights

  • Most APIs is similar as the coresponding data structures in the standard library
    • Use Vecx just like Vec
    • Use Mapx just like HashMap
    • Use MapxOrd just like BTreeMap
  • ...

Compilation features

  • rocks_backend, use rocksdb as the backend database
    • Stable ?
    • C++ implementation, difficult to be compiled into a static binary
  • [ DEFAULT ] parity_backend, use parity-db as the backend database
    • Experimental ?
    • Pure rust implementation, can be easily compiled into a static binary
  • msgpack_codec, use rmp-serde as the codec
    • Faster running speed than json
  • json_codec, use serde_json as the codec
    • Better generality and compatibility
  • compress, enable compression in the backend database

NOTE

  • The serialized result of a vsdb instance can not be used as the basis for distributed consensus
    • The serialized result only contains some meta-information(storage paths, etc.)
    • These meta-information are likely to be different in different environments
    • The correct way is to read what you need from it, and then process the real content
