  • 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
