Unofficial Ydb Client library

There is an alternative of ydb

Targets:

• more usability
• more freedom to use wrappers or raw objects from grpc bindings
• ability to create your own implementation of common traits, like Credentials
• easy to use pool objects

Goals:

• YQL Query for data (like DML)
• YQL Query for sheme (like DDL)
• Connect over grpcs (with tls)
• Connect over grpc (without tls) - not worked, unknown cause
• Connection pool (with deadpool) (feature pool)
• Token authentication
• Service account key authentication (feature auth-sa)
• Metadata authentication
• Query helpers (a lot of)
• sqlx integration - partially done (feature sqlx):
  • Connection string
  • connection
  • binding parameters
  • preparing statements
  • transaction manager
  • DML (data) operations
  • DDL (scheme) operations
  • primitive types (bool, i8, i32, i64, u8, u32, u64, f32, f64, Vec<u8>, String)
  • date types (Date, Datetime, Timestamp, Interval)
  • json type (Json, JsonDocument)
  • Decimal type
  • connection pool balancing for discovery
  • compile-time checked queries
  • migrations
  • multiple transaction modes
  • log statements
• operation parameters
