## What it is
A Node.js CLI tool (elasticdump) for importing and exporting Elasticsearch and OpenSearch indices, moving data between clusters or to/from files and S3. It supports per-index dumping of mappings and data plus multi-index operations via multielasticdump.

## Use cases
- migrate elasticsearch indices to a new cluster
- backup opensearch index data to a file
- copy elasticsearch mappings between environments
- export search index to json for offline analysis
- restore an elasticsearch index from a dump file
- transfer indices from elasticsearch to opensearch

## When to choose
- you need a simple, scriptable way to move or back up Elasticsearch/OpenSearch indices
- you are migrating between clusters or from Elasticsearch to OpenSearch
- you want per-index control over mappings and data dumps

## When to avoid
- you need full cluster snapshot/restore with built-in version guarantees (use Elasticsearch snapshot API)
- you require strict record ordering during transfer
- you need continuous replication rather than one-off dumps
