Infering Json Schema Aggressively Drops Nulls #1459

Open AustinMReppert opened 1 year ago

AustinMReppert commented 1 year ago

When a JSON schema is inferred, the approach seems to be discarding null values.

{ "a": null }, { "a": null }, { "a": null }

Instead of having one null column with the name "a", no columns are produced.
