HeartSaVioR opened a new pull request, #55226: URL: https://github.com/apache/spark/pull/55226
### What changes were proposed in this pull request? This PR proposes to introduce a new API "scan/scanWithMultiValues" in StateStore. This new API is mostly an optimization focused on RocksDB state store provider. The new API receives startKey (inclusive) and endKey (exclusive), and provides valid entries in the range. Since the API implies we have orderliness between startKey and endKey, the caller should be aware of the ordering for the keys, most likely being coupled with state key encoders, e.g. range scan encoder, timestamp prefix/postfix encoder. ### Why are the changes needed? This will enable the pattern of range scan to optimize further, effectively skipping tombstones and valid keys in both sides (before the lower bound, after the upper bound) within CF. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? New UTs. ### Was this patch authored or co-authored using generative AI tooling?
