i have 4 files which are getting input and then union in the start of the workflow.
The whole workflow runs in around 40 seconds, until last month.
This month I am facing a weird issue.
3 out of 4 inputs are stuck on 1% while 1 is stuck at 39% for forever.
When I remove 1 specific file ABC, the workflow runs in 20 seconds with 3 inputs, when I connect it back, it is back to stuck at above % for 3 files which were running without any issue.
When I input that specific file alone, it is again getting input in like 15 seconds.
That specific file isn't event too big, comparable to every month's file with around 200K records and the schema of each of the 4 files is exact same.
Any help or workaround without changing the combined input for union, will be appreciated.
