Elasticsearch: reindexing and zero-downtime migration

When to use

Use this skill for reindexing and zero-downtime migration in Elasticsearch. This skill specifically handles reindexing and zero-downtime migration and nothing else in the Elasticsearch family.

Procedure

Use the reindex API with aliases to migrate data to a new mapping, throttle reindex, and cut over with zero downtime.

Notes

This is the Elasticsearch skill dedicated to reindexing and zero-downtime migration. Sibling skills cover other Elasticsearch capabilities; this one is the right choice only when the task is about reindexing and zero-downtime migration.
