Olga Natkovich commented on PIG-1822:
-------------------------------------
While figuring out what information is missing from the type related
documentation, I found that we have duplicated paragraphs under Schema section:
Schemas
Schemas enable you to assign names to fields and declare types for fields.
Schemas are optional but we encourage you to use them whenever possible; type
declarations result in better parse-time error checking and more efficient code
execution.
Schemas for simple types and complex types can be used anywhere a schema
definition is appropriate.
Schemas are defined with the LOAD, STREAM, and FOREACH operators using the AS
clause. If you define a schema using the LOAD operator, then it is the load
function that enforces the schema (see LOAD and User Defined Functions for more
information).
