- Can we wrap this with a static method so we can change implementation easily?
- If we go ahead with this approach, please add comment regarding this is not ideal solution.
- What does the suffix

7DOT8 is referring to ES 7.8.
"_ttl" and "_timestamp" were removed in ES6. See https://www.elastic.co/blog/elasticsearch-5-0-0-alpha4-released
"_type" was renamed to "_nested_path" in OS 2: opensearch-project/OpenSearch#3196
"_size" is not a built-in metadata mapper, it comes from the mapper-size plugin which is not installed by default. Using mapperService.isMetadataField("_size") should return true if the mapper-size plugin is installed in the cluster.
The other values in this list still exist and are built-in metadata fields so mapperService.isMetadataField() should return true.
