Practise the standard verbs for resharding a Redis cluster safely.

1 / 5
Fill in: 'We ___ hash slots gradually to a new node so a Redis cluster resharding never blocks live traffic.'
We 'migrate slots' — the standard, established Redis Cluster collocation for moving hash slot ownership. The other options aren't the recognised term here.
2 / 5
Fill in: 'Adding a node without rebalancing slots can ___ the cluster with one node holding almost all the data.'
We say an unbalanced add will 'leave' the cluster skewed — the standard, natural collocation here. The other options aren't idiomatic here.
3 / 5
Fill in: 'We ___ resharding during low-traffic hours since moving slots still adds some latency to affected keys.'
We 'schedule' an operation — the standard, simple collocation for timing maintenance work. The other options are less idiomatic here.
4 / 5
Fill in: 'We ___ cluster state with CLUSTER INFO after resharding to confirm every slot is owned and none are left orphaned.'
We 'check' state — the standard, simple collocation for verifying a system's status. The other options are less idiomatic here.
5 / 5
Fill in: 'We ___ redirected MOVED responses in the client driver so a request during resharding still reaches the right node.'
We 'handle' a response — the standard, simple collocation for processing a protocol-level signal. The other options are less idiomatic here.
