description

@Deniz-Jasa & i paired a bit on this, and it looks like there's some nuance to the problem, but this reproduces the original problem & demonstrates that it's up to pagination not working.

notes

fun fact1: Temporal advises that page size limits are suggestions, not concrete guarantees. it turns out that concurrent execution will result in all history events returning in a single batch.

that is, if you modify the test workflow in this PR to call Workflow.forConcurrently_ then the test will pass!

Footnotes

  1. actually not fun! very annoying!!
