Benjamin Lerer updated CASSANDRA-9632:
--------------------------------------
Attachment: 9632-2.2.txt
{{OptionsWithNames}} is used for prepared statement with named parameters, but
as specified in the native_protocol specifications the parameter names are
optional. The java driver and the python driver for example do not return them.
[~thobbs] indicated me that we store the bound names in the
{{ParsedStatement.Prepared}}. The patch retrieve the column specification from
theres and make them available for any prepared statement through the
{{QueryOptions.hasColumnSpecifications()}} and
{{QueryOptions.getColumnSpecifications()}} methods.

> When writing a custom {{QueryHandler}} that processes named parameters, the
> {{QueryOptions}} arrive to the various processing methods with the values
> converted to positional arguments and the names unavailable. A custom
> {{QueryHandler}} might want to make use of the names themselves so it would
> be helpful if they were preserved and exposed with their respective
> {{ByteBuffer}} values.
