This PR changes the `TimeOrderedKeySchema` composite key from `time-seq-key` -> `time-key-seq` to allow deletion of duplicated time-key records using the RocksDB `deleteRange` API. It also removes all duplicates when `put(key, null)` is called. Currently, the `put(key, null)` was a no-op, which was causing problems because there was no way to delete any keys when duplicates are allowed. The RocksDB `deleteRange(keyFrom, keyTo)` deletes a range of keys from `keyFrom` (inclusive) to `keyTo` (exclusive). To make `keyTo` inclusive, I incremented the end key by one when calling the `RocksDBAccessor`. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
