@ivancea what's the blessed way to address the mixed-cluster tests failing?

[ivancea]

@mjmbischoff I see the error is the change of empty string behaviour. We'll need to make a new capability for it , to avoid running those tests against versions with the old behaviour. (Or rename the existing cap to something like *_V2, which should do the same "reusing" the old capability)
After changing the capability in the test, it should not fail.

I'd pass the scratch in for this in BytesRefBlock. One scratch per position feels like a lot.

[mjmbischoff]

ah yes, long day. Renamed it to position.

I've moved the scratch up one level though in the back of my mind I do wonder if we'll have a net gain from this as we might just break escape analysis 'a stack too far' so to speak.

💔 Backport failed

The backport operation could not be completed due to the following error:

There are no branches to backport to. Aborting.

You can use sqren/backport to manually backport by running backport --upstream elastic/elasticsearch --pr 135991
