On one side this will not open 2 failures (for SYNC and for ASYNC) when the test fails, on the other side I am wondering if it might be important for us to know in what mode has failure happened? Can we reproduce the mode with the seed?

@idegtiarenko In theory, yes, the seed should be enough. The mode is now calculated with a random() here: https://github.com/elastic/elasticsearch/pull/131949/files#diff-e5229c7428590a22294db189f7845ae0fadefc37b2154c5da1f1dc85804bcaecR121

The seed should be enough, yeah.
