Can not enable allow_db_generated_files in Java lib in IngestExternalFileOptions

[yixiwang29]

Hi rocksdb owner,

I'm trying to ingest sst files into my rocksdb which was generated by DB in Java project. The version of rocksdbjni is 10.10.1. I see the allow_db_generated_files option has already supported after 9.5 (wiki). But unfortunately I can not find any valid config from org.rocksdb.IngestExternalFileOptions. Can anyone help take a look?

The exception I encountered without allow_db_generated_files=true: External file version not found

Hi, I’d like to work on this. I’ll look into exposing IngestExternalFileOptions::allow_db_generated_files through RocksJava with setter/getter support and a focused Java/JNI test if there is an existing options test pattern.

Thanks a lot @richinmrudul!! Please let me know once you release it

Thanks! I opened the PR here: #14793. I’m not a RocksDB maintainer, so I can’t control when it gets merged or released, but if it lands you should be able to track the release through the RocksDB release notes/tags.
