They do different things. Deleting mutations marks each entry with a delete marker. Using the iterator marks a whole row with a single mutation.
If you have a million entries in your row, the iterator is faster for the delete, but requires a seek to the start of the row for every read, so reads are slower. If your row has one entry, they are the same thing. Somewhere under N keys... the mutation path will be quite fast, and still preserve your reading speed. I'll just pull a number out of thin air... let's say a few thousand. -Eric On Wed, Oct 9, 2013 at 4:01 PM, David Medinets <[email protected]> wrote: > Are there any reason to favor one approach over the other?
