> why do you think this is an index lookup problem? And why does it happen inky on the delete and not on the upset operation? @dmenin I was more into the problem you had with GLOBAL index. So proposing some improvements there. For delete slowness, are you using COW table? assuming yes, the data you insert with "upsert" mode, they are looked up and determined as "new" records then went to new files. while each delete op resulted in re-writing an existing base file which can be time-consuming. -- This is an automated message from the Apache Git Service.
