## Problem `test_sharding_autosplit` is occasionally failing on warnings about shard splits taking longer than expected (`Exclusive lock by ShardSplit was held for`...) It's not obvious which part is taking the time (I suspect remote storage uploads). Example: https://neon-github-public-dev.s3.amazonaws.com/reports/main/9618788427/index.html#testresult/b395294d5bdeb783/ ## Summary of changes - Since shard splits are infrequent events, we can afford to be very chatty: add a bunch of info-level logging throughout the process.
