-------------------------------------------------------------------
You can specify defaults to struct values, but I'm not sure about default
method parameters -- few languages support this functionality, so I doubt it.
It may be premature generalization, but the second option would allow you to
have a default:
struct ConsistencyRequest {
1: required ConsistencyLevel level = ONE,
2: optional int nodes,
}
read(1: string thing, 2: ConsistencyRequest request)

> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Michael Greene
>
> Currently, a user has to specify an int for the number of nodes to block_for.
> As discussed on IRC, there are only a few options that a user would want, so
> this would be better encapsulated by an enum.
> enum ConsistencyLevel {
> ZERO = 0,
> ONE = 1,
> QUORUM = 2,
> ALL = 3,
> }
> This could be extended with a fifth option, CUSTOM = 4, if custom
> specifications are desired
> struct ConsistencyRequest {
> 1: required ConsistencyLevel level,
> 2: optional int nodes
> }
