Client SDK:除了Web UI访问外,还给Python用户和DuckDB CLI用户提供了SDK,调用时通过MotherDuck的Token进行身份认证后可以直接从该Client访问MotherDuck;并支持在JDBC Driver, Go Driver, DBeaver, Alchemy等终端进行访问; (MotherDuck官方文档中阐释的产品架构) (2)从Web UI接入 MotherDuck目前采用的云端技术方案是:域...
Async I/O:当算子执行blocking IO时可以暂停执行,有数据后再继续执行。e.g. HTTP Scan 实现了Radix Partitioning HashJoin。 Storage DuckDB采用了 single-file block-based 的存储格式,WAL存储到单独的文件中,通过block header实现ACID: 每张表会存储为多个row group(120K~ rows),row group内部是列存,row group...
