I am collecting OPC UA data with Telegraf using the OPC-UA plugin. All is good and works as expected. I can read data from my server and I can see the data into QuestDB. However, since Telegraf is getting each different metric as a different row, I end up with a sparse dataset in which for each row I have only the timestamp, the tags, and the value for one column, even when the metrics in such columns are from the same exact timestamp.
