In kibana 5, viz used to be saved under _type=visualization. It was net because I could then programmatically insert viz from outside kibana by just writing to this index.
In kibana 6, however, this does not exist anymore. Is this change associated with the doc type mapping changes in 6.0? Is there a way to query all kibana viz in 6.0?
Another question, I currently distinguish users by a unique email id field. In other words, I take the same dashboard and set filter by email id to make them unique to every user. Is this a recommended way to separate out users? This is to avoid creating a separate index for every user.
Dashboards are then made available via iframe. However, the embed URL does not seem to contain the filter parameters that I can programmatically set. Only the snapshot does. How else woudl I achieve this?
