esreindexer

Makes reindexing of existing data in elasticsearch easy.

Why?

Because you may do poor choices that you regret later. Reindexing combined with aliases can help you change mapping, routing or whatever you want to change that requires reindexing.

Speed

Speed of reindexing is mostly limited by elasticsearch. We use scrolling to fetch data and parallel bulk indexing for insertion data back into elasticsearch.

Usage

Use docker image:

docker run --rm -it bobrik/esreindexer

It will print command line options to use.
