👍 Thanks to @HollayHorvath and @frankyn! The code to create a directory placeholder changes from blob = bucket.blob(name)
if not blob.exists():
blob.upload_from_string(b'', content_type=OCTET_STREAM)to blob = bucket.blob(name)
try:
blob.upload_from_string(
b'', content_type=OCTET_STREAM, if_generation_match=0)
except PreconditionFailed:
passbecause, as the doc says, "Setting to 0 makes the operation succeed only if there are no live versions of the blob." In a handful of timings, the new code saved more than half the didn't-exist time and a bit of the already-exists time (although that might be measurement noise). |
