Looking Up Data in Another Table by Key

Hi everyone,

I've seen a post or two about the needs for SQL-like joins and being a little new to Elasticsearch, I wanted to get some feedback as to the best approach for some data visualization. I am getting SNMP data from a wireless controller using Telegraf. The data sits in two distinct datasets but has the same timestamp. It's one set (FOO) that has elements A, B, and C with values in each. The other set (BAR) has C and D with values in each.

What I am trying to do is as follows:

For every timestamp, find every value of BAR.D where FOO.C and BAR.C are equal and create a new dataset with timestamp, FOO.A, FOO.B, FOO.C, BAR.D.

I am not the greatest programmer in the world and have put about 30 hours into the effort so far and have come up empty, other than learning a ton which is always a good thing. I tried using Kapacitor to do a join but couldn't make it work the way I wanted. I also tried using Python with PySNMP and managed to gather the data together, and that's the path I'm currently taking, but I think there has to be a better way.

I'm willing to do just about anything in terms of collection mechanisms and data storage, and just think Elasticsearch has to be able to do something like this.
