[Xuanwo]

Signed-off-by: Xuanwo github@xuanwo.io

I hereby agree to the terms of the CLA available at: https://databend.rs/dev/policies/cla/

Summary

See RFC-0041: #41

With this refactor, we improve the performance on fs a lot:

• On my PC: the throughput increased from 400MB/s to 800MB/s
• On benchmark on databend sides: time for the same query will drop from 0.8s to 0.37s

Unresolved problems

• We need to support construct Object via external information
• Maybe find a better name for stateful_read.
