Amazon-Redshift – Redshift: Unable to complete due to concurrent transactions

I encountered this error: Unable to complete due to conflict with concurrent transaction.

I did not find other queries that conflict with this conflict.

I tried:

>Use AWS charts/indicators in the online console.
>View STL_TR_CONFLICT
> STL_QUERY to select the query that runs while I fail.

p>

None of these options help me understand the problem. I found that some queries are running at the same time, but they are not using the same table.

Restarting the query after a few minutes works fine.

p>

I found that I encountered this problem when the following transactions were running at the same time:

< p>> drop / create my_schema.my_table as …> Grant select option on all tables in schema my_schema<-this one failed
