+# elastic-copy
+Copy data from / to elasticsearch very fast
+
+## Motivation / use case
+
+``elasticdump`` is a very nice tool for copying a single index to another server. 
+
+But sometimes, you need to copy more than a single index, and as fast as possible!
+
+This why I build ``elasticcopy``.
+
+## Multi threading
+
+``elasticcopy`` is fast, because it use multi threads to copy data in parallel. 
+
+The parallel unit is a ``shard``, if you want to copy 12 indices of 3 shards, this will create 36 tasks.
+
+## Usage
+
+```
+elasticcopy --source=http://localhost:9200 --target=http://prod:9200 --indices=events-1,events-2 --threads=12
+```
