bobrik/esreindexer repository overview

⁠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.
