Hi there,
Just wanted to know what the general guidelines/best practices are regarding fields.yml which is used for creating index template.
The out-of-box fields.yml has hundreds of fields and we are not even using most of it.
1- Is it a good practice to remove the unwanted fields and actually add our own custom fields into fields.yml ?.
2- Can the out-of-box fields.yml cause performance issue since there are so many fields. Does ES internally really care about the unused fields. (fields with no data).?
3- If we do customize, then are "setup.template.name|pattern|fields" the correct config properties to set.
Thanks
John
