  }
}

Please Note:

  • The table data would mostly be generated from "vehicle", but I would be filtered by "event.timestamp.unix over the last 24 hours, where ecu_config.exists = yes"

  • I have total control over the JSON data format, AND how to normalize the organization of documents into Elasticsearch for indexing

Could support help me to accomplish this?

Thank you

This look like a continuous transform usecase to me. If I understand correctly you have a constant stream of new data coming in and want to get the last state by vehicle. A similar question came up today: Latest full document in transform

To get an idea I suggest to watch this webinar. It goes much beyond your original case. But even if you "only" want a table like shown, you might want to calculate trends (e.g. value based on the last 5 data points).

Alternatively you could directly search and aggregate instead of transforming 1st.

Excellent! Thank you for giving me someplace to start
