Yu Zhang 3db030d7ee Fix bug for recovering a prepared but not committed txn (#12856)
Summary:
This PR fix a bug for recovering a prepared Transaction that can contain user-defined timestamps.

The `Transaction::Put` type of APIs expect the key provided to be user key without timestamps. When the original transaction added a key for a column family that enables user-defined timestamps, say of size 8. Internally `WriteBatch::Put` will leave a placeholder 8 bytes for the final commit timestamp. For example:
cec28aa90f/db/write_batch.cc (L937)

When rebuilding this transaction from a `WriteBatch` from WAL log, we should consider this and remove the tailing 8 bytes of a key before adding it via the public Transaction write APIs.

Test Plan: Added unit test that would fail without this fix

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

CircleCI 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/main/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.
