Joining elasticsearch indeces


I have one index as oracle_table. I am using jdbc connector in logstash to gather data from db to oracle_table index. query is working every minute. I need one information from another db. I can create another index for this db but i dont know how to merge those index?

first index, oracle_table feeding every minute, other table is static. I just need one information from it and add oracle_table index as a field.

How is possible? Can apache spark make it? or another things?
