Use Case

1. Create test data
2. Open Data explorer > Script editor
3. Create a flux script using join

Smichov = from(bucket: "test-data")
  |> range(start: -4h)
  |> filter(fn: (r) => r._measurement == "air_quality")
  |> filter(fn: (r) => r.location == "Smichov") 
  |> filter(fn: (r) => r._field == "SO2")
  |> drop(columns: ["gps", "label", "location", "unitId" ])
  
Hlavni = from(bucket: "test-data")
  |> range(start: -4h)
  |> filter(fn: (r) => r._measurement == "air_quality")
  |> filter(fn: (r) => r.location == "Praha hlavni") 
  |> filter(fn: (r) => r._field == "SO2")
  |> drop(columns: ["gps", "label", "location", "unitId" ])
  
  
join(tables: {key1: Smichov, key2: Hlavni}, on: ["city", "_field", "_measurement", "_start", "_stop", "_time" ], method: "inner")

Note that when adding the join function the tooltip document suggests other types of joins are possible (e.g. left, right, cross, full)

4. Change the join method from "inner" to "left" and click submit.

An error message indicates that "left is not a valid join type".

Question

I realize that this is pre-beta. Is there any idea of when the other join methods will be supported? And, if they are not supported at next release. shouldn't the tooltip document reflect currently supported possibilities?
