Coerced and Out of order partitions

Hello Everyone,

I am trying to write a matrix table with a count of (47099730, 1058) to ouptut.mt file in my server.

However, it’s been running for more than an half an hour.

And I see the below repeating messages. May I know what does the below message mean?

2020-09-12 01:00:25 Hail: INFO: Coerced almost-sorted dataset
2020-09-12 01:00:25 Hail: INFO: Coerced dataset with out-of-order partitions.
2020-09-12 01:06:18 Hail: INFO: Coerced almost-sorted dataset
2020-09-12 01:06:18 Hail: INFO: Coerced dataset with out-of-order partitions.

These mean additional scans of the data were performed, but that it was already sorted and so no additional work is necessary. What’s your full pipeline?
