Bug#28573894 ALTER PARTITIONED TABLE ADD AUTO_INCREMENT DIFF RESULT DEPENDING ON ALGORITHM
Problem:
When a partition table is in-place altered to add an auto-increment column,
then its values are starting over for each partition.
Analysis:
In the case of in-place alter, InnoDB is creating a new sequence object
for each partition. It is default initialized. So auto-increment columns
start over for each partition.
Fix:
Assign old sequence of the partition to the sequence of next partition
so it won't start over.
