Datenbanken nicht-ORM und Scala

Question

Was ist die beste nicht-ORM-Datenbank zur Arbeit mit Scala? Ich finde diesen Link Link-Text , aber das beantwortet nicht meine Frage voll.

Könnte wünschenswertes Merkmal Leistung, Skalierbarkeit und Einrichtung schreiben komplexe Strukturen von Beziehungen zwischen Daten berücksichtigt werden.

Danke

Answer 1

Do you mean non-relational? There are Scala client libraries/wrappers for many NoSQL databases, including Cassandra, MongoDB, Redis, Voldemort, CouchDB, etc.

If by "complex structures of relationships between data" you mean that you'd prefer not to have to normalize, any NoSQL database should do reasonably well.

However, note that none of them--to my knowledge--will do anything like enforcing a referential integrity constraint or dereferencing object navigation paths for you. For that you may want to consider a graph database or OODBMS; unfortunately I'm not aware of any that's open source, liberally licensed and clusterable.

Update: I just found OrientDB which actually meets all threetwo of these criteria.

Update 2: OrientDB's clustering support isn't released yet. As a wise man once said, two out of three ain't bad.

Answer 2

The best solution is probably not to worry about it...

Abstract away from the problem by using the pluggable-persistence support in Akka: http://doc.akkasource.org/persistence

Then you can try them all, and take your pick based on profiling results :)
