Indexes are updated at the same time an entry is mutated. So a slow value extractor used for an index can impact write performance (and yes we have seen people try to access a DB from an index extractor 😮). Indexes are not backed up so when a partition moves, due to redistribution on member join or member left, then the indexes are rebuilt for the moved partitions.

Queries are blocked until the index has finished building.
Releated to your other questions about reading from nearest cluster member, queries will always execute on the primary owners. This makes sense really as a query is cluster wide anyway so will run on all cluster members (unless it is a partitioned query, which is restricted to specific partitions).
