> CDC Avro schema conversion fails for UDTs with quoted names containing

> -------------------------------------------------------------------------------------------------
>
> Key: CASSANALYTICS-216
> URL: https://issues.apache.org/jira/browse/CASSANALYTICS-216
> Project: Apache Cassandra Analytics
> Issue Type: Bug
> Components: CDC
> Reporter: Bernardo Botella Corbi
> Assignee: Bernardo Botella Corbi
> Priority: Normal
> Fix For: 0.5
>
>
> CASSANALYTICS-204 changed the Avro record for a UDT to be named after the
> UDT. It had been the constant record_udt. The name is now
> userType.getNameAsString(), passed unchanged to SchemaBuilder.record(...) and
> into the nested namespace in
> CqlToAvroSchemaConverterImplementation.schemaFrom.
> Quoted CQL identifiers can contain any character, but Avro names must match
> [A-Za-z_][A-Za-z0-9_]*. A UDT such as CREATE TYPE "my-type" (id text)
> therefore makes convert(CqlTable) throw for any table that uses it. This is a
> regression, because before CASSANALYTICS-204 the UDT's own name never reached
> Avro.
> The proposed fix is to sanitize those names and avoid collisions appending a
> number to those names.
