Whether or not to fsync and commit the translog after every index, delete, update, or bulk request. This setting accepts the following parameters:, 9/26/2016 · If you want to prioritize indexing performance over potential data loss, you can change index.translog.durability to async in the index settings. With this in place, the index will only commit writes to disk upon every sync_interval, rather than after each request, leaving more of its resources free to serve indexing requests.
As index.translog.durability is a dynamic setting, I think we should make this one dynamic as well. In terms of implementation, it can reuse the same triggers we have build to make index.translog.durability dynamically switchable. Could be a adoptme / low-hanging.
