Philip Thompson updated CASSANDRA-9228: --------------------------------------- Fix Version/s: 3.0 > Add documentation for Type Cast, Type Conversion and Function Overloading > ------------------------------------------------------------------------- > > Key: CASSANDRA-9228 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9228 > Project: Cassandra > Issue Type: Task > Reporter: Michaël Figuière > Priority: Minor > Fix For: 3.0 > > > While digging around UDF overloading and type conversion it appeared that > several topics aren't currently documented in the CQL spec: > * Explicit type casting has been added with CASSANDRA-5226 in Cassandra 1.2.2 > and is currently not explained in the spec. > * UDFs support overloading, this should be explained in the CQL spec, along > with a clear definition of what is considered as an ambiguous function call. > * In this context it also becomes important to document the type conversion > rules, that is, which type A can be converted to which type B without raising > an error. > * Not directly related but it would also be useful to document the column > type changes that are allowed in {{ALTER TABLE}} statements. > All these fairly important topics are currently not obvious or hard to figure > out for the user. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
