The following two cases will create an empty destkey HLL: 1. called with no source keys, like `pfmerge destkey` 2. called with non-existing source keys, like `pfmerge destkey non-existing-source-key` In the first case, in `PFMERGE`, the dest key is actually one of the source keys too. So `PFMERGE k1 k2` is equivalent to `SUNIONSTORE k1 k1 k2`, and `PFMERGE k1` is equivalent to `SUNIONSTORE k1 k1`. So the first case is reasonable, the source key is actually optional. And the second case, `PFMERGE` on missing keys should succeed and create an empty dest. This is consistent with `PFCOUNT`, and also with `SUNIONSTORE`, no need to change. |
