Hello there, RocksDB has the feature called "Compaction Filter" to allow application to modify/delete a key-value during the background compaction. https://github.com/facebook/rocksdb/blob/v4.1/include/rocksdb/options.h#L201-L226
I'm wondering is there a plan/value to add this into C* as well? Or is there already a similar thing in C*? Thanks -- Dikang
