Is there any way to diff two snapshots in rocksdb?
In RocksDB, you can compare two snapshots by using their sequence numbers. You won't directly diff snapshots in the traditional sense, but you can use the sequence numbers to determine the differences in key-value pairs between the two snapshots. Here's a general approach to achieve this: 1. Get the sequence numbers of the two snapshots you want to compare. ```cpp uint64_t snapshot1_seq = snapshot1->GetSequenceNumber(); uint64_t snapshot2_seq = snapshot2->GetSequenceNumber(); ``` 2. Iterate over the keys and values in one of the snapshots (e.g., snapshot1) and compare them to the keys and values in the other snapshot (e.g., snapshot2). ```cpp rocksdb::ReadOptions read_options; read_options.snapshot = snapshot1; // Use snapshot1 rocksdb::Iterator* iter = db->NewIterator(read_options); for (iter->SeekToFirst(); iter->Valid(); iter->Next()) { rocksdb::Slice key = iter->key(); rocksdb::Slice value = iter->value();
