Re: Amend Entire Works in memory but not with a handle?

[cillianreilly]

I think this is due to the constraints specified here: https://code.kx.com/q/ref/amend/#on-disk, in particular that only vectors of types 1-19 can be updated directly on disk. Given that weirdPartition has type 0, it can’t be updated on disk, but has no such constraints in memory.

Note: Personally unclear on whether the wording on the above link (“Certain vectors (types 1-19) can be updated directly on disk without the need to fully rewrite the file. “) means it can’t be done, or it can be done but that the entire file must be rewritten, and there is another issue at play here. I’m leaning towards the former, and that modifications must be done in memory first before writing.
