Hey Pants Team, I'm testing a possible upgrade from

2.17.1

->

2.19.0

the first run is extremely slow on the rule

Find all targets in the project

, took about +10mins. Is this something we should expect when upgrading versions? Our repo is rather large so I wonder if we are hitting a performance issue with target expansion.

We changed the dependency inference cache format version, IIRC with 2.18. So Pants would need to rebuild all dep information. If subsequent runs are fast I think that's the explanation. In general, I think that upgrading versions will cause more cache misses, since codepaths that changed in Pants from one version to the next will need to be recomputed.
