Feature request: Automatic insertion based on index

[mkoenig3]

Hi Norman,

it would be great if there was a feature to make sure that newly appended data is inserted at the correct index location. For example, it would be cool if new data would be placed correctly along the 'time' dimension.

Thanks,
Marcel

With the new append_step setting (#21) we could calculate the correct index location you are referring to and then update the location (#29) given that we have inserted empty dummy slices before appending a slice that is a multiple of append_step away from the last coordinate (another new feature).

If your feature request just concerns the order of slices that are appended in one invocation of zappend, then you could of course sort them on your own before passing the to zappend.

However, if data doesn't have a fixed append step size, but is strictly increasing or decreasing (#20) we could compute an insert location, but then all the subsequent steps would have to be shifted by the number of slices inserted. I feel, this is out-of-scope, as this would potentially require very large temporary storage for the rollback operation.

Thanks Norman, I agree! Sorting the slices should do for me, too.
