In ES:
The
copy_to
parameter allows you to create custom_all
fields. In other words, the values of multiple fields can be copied into a group field, which can then be queried as a single field.
Right now CrateDB does not support having such a dynamic column based on a combination of other columns. Do we have such a feature in pipeline?
