  1. You loose the ability to query it together. If it has a similar schema then writing it all to the same measurement will allow you to correlate the data. In that situation you would distinguish the data sources with a tag (source=foo).
  2. Nope!
  3. You can think of measurements as tables in SQL, tags as indexed columns, and fields as unindexed columns. Does this help?
  4. This should work for you. Give it a test though. We made some backup changes for the 1.2 release so make sure you are using the latest.
