This topic got automatically closed without an answer I want to know why the indices.id_field_data.enabled configuration is turned off by default
I'm evaluating the impacts of upgrading from v7 -> v8 and found an issue with indices.id_field_data.enabled now not enabled by default. In v7 it is, in v8 it's not. Why ?
I can't actually find specific doc for this configuration. I can somewhat infer what it does based on the doc for the
fielddata setting on the mapping Text type family | Elasticsearch Guide [8.9] | Elastic and assume it's because it can use significant memory but also I could be totally off and could use some explanation from the elastic folks.
