I have a partitioned table that uses monthly tem****al partitions.
Every night I want to load the last 10 weeks of data into a separate
non-partitioned table.
Currently, I truncate the destination table, drop the indexes,
execute:
"INSERT INTO destination SELECT * FROM source_partition"
and recreate indexes.
This loads about 66.5 million rows into the destination table in about
1 hour. Recreating of indexes (4 of them) takes additional 2 hours. Is
there a more efficient way to perform this procedure?
Thanks.
