I'm using Elastic 2.4 .
I'm trying to update mappings, but it takes 30 hours for Elastic with 9M documents.
I'm running on a machine with 360 GB RAM, and Elastic is running with 30 GB.
- Is there a quick option to run the update mappings much faster ? maybe in parallel processes ?
- Is it possible to read documents from Elastic when update mapping is running ?
