I wanted to know if there is a feature in ElasticSearch that allows you to create a template for column names. If I wanted to define something like: All column names beginning with AAA_ should be a keyword. For example if I already had 3 columns AAA_1, AAA_2, AAA_3 defined as keyword. Is there a way for me to create a template that would make any new column that starts with AAA_ to be a keyword?
