Open issues:
Collection results
What about collection result types like lists and sets? Should these be dissolved into particular elements?
Iterables
Sync API:
// sync API
List<String> result = redis.hkeys("...");
Rx API:
// either
Observable<String> result = redis.hkeys("...");
// or
Observable<List<String>> result = redis.hkeys("...");
Maps
Sync API:
// sync API
Map<String, String> result = redis.hmget("...");
Rx API:
// either
Observable<KeyValue<String, String>> result = redis.hmget("...");
// or
Observable<Map<String, String>> result = redis.hmget("...");
PubSub
Provide hot observables for subscription listeners?
Cluster
Provide observable commands also for node-selection commands? (Commands executed on multiple cluster nodes)

What would be the advantage of emitting List<String>
(Iterable!) over simply String
?
Grouping could be done using groupBy
operator.
from lettuce.
None.
Rx does not differentiate between one and many elements. Dissolving Iterable
s and other multi-element containers such as Map
into singular values or tuples fit very well into the Rx pattern. This is, however, a change of result types in contrast to other API's within lettuce.
If you approach from pure Rx dissolved elements are welcome, but if you're used to List
s and Map
s then you have to shift from collections to reactions on elements.
