• more usability

• ability to create your own implementation of common traits, like Credentials
• easy to use pool objects

Features:

• 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)
• Token authentication
• Service account key authentication
• Metadata authentication
• Query helpers (a lot of)
• Connection string
