AnkaDB is now single-node and will soon support multiple nodes, using the raft protocol.
AnkaDB queries and modifies data with GraphQL.
AnkaDB used GRPC & ProtoBuf v3.

TradingDB is an implementation of AnkaDB.

Key-Value sample is here.
GraphQL sample is here.

How To Upgrade v2 To v3

  • change *AnkaDB to AnkaDB.
  • change Config to *Config.
  • change MgrDB to GetDBMgr().
  • remove your dblogic, and use ankadb.NewBaseDBLogic new a DBLogic.
  • Config.ListDB.PathDB doesn't require join Config.PathDBRoot.
  • you can remove all the query result definitions, and use MakeMsgFromResultEx to resolve the query result.
