Cheng Chang ada700b906 Re-read the whole request in direct IO mode when IO uring returns partial result (#6853)
Summary:
If both direct IO and IO uring are enabled, when IO uring returns partial result, we'll try to read the remaining part of the request, but the starting address/offset of the remaining part might not be aligned to the block size, in direct IO mode, the unaligned offset causes bug.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6853

Test Plan: run make check with both direct IO and IO uring enabled, this is covered by one of the continuous tests.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

Linux/Mac Build Status Windows Build status PPC64le Build Status

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/ and https://rocksdb.slack.com/
