Nicolas Pépin-Perreault 9e6f3efcd2 Add RocksIterator::Refresh (#6573)
Summary:
This PR exposes the `Iterator::Refresh` method to the Java API by adding it on the `RocksIteratorInterface` interface. There are three concrete implementations: `RocksIterator`, `SstFileReaderIterator`, and `WBWIRocksIterator`. For the first two cases, the JNI side simply delegates to the underlying `Iterator::Refresh` method; in the last case, as it doesn't share an ancestor, and per the discussion in https://github.com/facebook/rocksdb/issues/3465, a `Status::NotSupported` exception is thrown.

As the last PR had no activity in a while, I'm opening a new one - I'm completely fine with merging the previous PR if it gets completed before this is reviewed.

Let me know if there's anything missing or anything else I can do 👍

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/
