Developer API

Registry of dialects that apply to every new jdbc org.apache.spark.sql.DataFrame.

If multiple matching dialects are registered then all matching ones will be tried in reverse order. A user-added dialect will thus be applied first, overwriting the defaults.

All new dialects are applied to new jdbc DataFrames only. Make sure to register your dialects first.
