Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/15342 Add an ExternalTableBuilderBase::TryAdd() contract so external table builders can distinguish accepted rows, real builder errors, and clean requests to cut the current output table and retry the same row. Add external-table-facing result, reason, and context types. Existing external table builders inherit a default TryAdd() implementation that forwards to Add(), so current implementations keep their historical behavior unless they explicitly opt into retryable file cuts.

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