Hi,

Regarding MergeOperator customization, I have read wiki page https://github.com/facebook/rocksdb/wiki/Merge-Operator-Implementation which is very useful.

I am wondering if there is a case "Merged Merge" and Merge operations could both appear in FullMergeV2/3 scenario ? "Merged Merge` means a Merge operation generated by a full merge.

For example, if the following case 2 and 3 will appear ?

1. [Put, Merge, Merge, Merge, ...], this is illustrated in the wiki

2. [Put, Merged Merge, Merged Merge, Merge, Merge, ...]

3. [Put, Merged Merge, Merged Merge, Merge, Merge, Merged Merge, Merge, ...], interleaved.
