Setting missing field to default value based on a master template
I will put my example in non elasticsearh language.
I have two tables table_a and table_b
table_a
Field1 Field2
table_b
field, field3
How do I make it such that after receiving data from Logstash, I can receive the following
table_c
Field1 Field2, Field3
Field 2 should contain a null or empty value
