CLUSTER MIGRATESLOTS initiates an asynchronous migration
of the designated slot range(s) to the specified target node using atomic slot
migration.
This command allows for many slot ranges in a single migration
through repeated start and end slot pairs within the
SLOTSRANGE block. It also supports multiple migrations in
one command, through repeated SLOTSRANGE and
NODE blocks. For example:
CLUSTER MIGRATESLOTS SLOTSRANGE 0 9 20 29 NODE <target A> SLOTSRANGE 10 19 NODE <target B>Initiates two slot migration jobs, one to
<target A> with 20 slots (0-9 inclusive, 20-29
inclusive) and another to <target B> with 10 slots
(10-19 inclusive).
OK is returned if all slot migrations are successfully
initiated, otherwise an error message is returned and no slot migrations
are initiated.
To check on the progress of the slot migration, use the CLUSTER GETSLOTMIGRATIONS
command.
O(N) where N is the total number of the slots between all start slot and end slot arguments.
