# This test checks mutations concurrent execution with concurrent inserts.
|
|
# There was a bug in mutations finalization, when mutation finishes not after all
|
|
# MUTATE_PART tasks execution, but after GET of already mutated part from other replica.
|
|
# To test it we stop some replicas to delay fetch of required parts for mutation.
|
|
# Since our replication queue executing tasks concurrently it may happen, that we dowload already mutated
|
|
# part before source part.
