UPDATE: I solved this for now by hardcoding in opt_mitosis a bailout condition for that specific function. Wouldn't it be useful to use a function marker for this, along the lines of {inline|unsafe} markers? Something like: blocking command myfunction(...); and then disable mitosis for all blocking functions (i.e. functions that need to consume their whole input)? On the same topic, I also noticed that mitosis currently isn't disabled on unsafe functions. Is that correct? If a function is unsafe, calling it multiple times could be... .. well ... unsafe? ;-) Roberto On 9 February 2017 at 15:10, Roberto Cornacchia < roberto.cornacchia@gmail.com> wrote:
I have implemented a custom join as a filter function. By design, it cannot work correctly when the input tables are partitioned by mitosis.
How can I prevent mitosis from partitioning its inputs?
