Introduce `ignore_above` index level setting #112795

Open salvatore-campagna opened 1 week ago

salvatore-campagna commented 1 week ago

Description

108720 will change the default value for `ignore_above` when LogsDB index mode is adopted. Before being able to do that we need to introduce a new index-level setting `ignore_above` that is applied to all text-like fields for a specific index mapping. The index level setting will default to `1024`. Text-like field mappings will be able to override the index level setting using `ignore_above` with the mapping-level setting taking precedence on the index-level setting.
