I may be developing an application which will need a persistent, ACID local database (on the same disk as the application, rather than having to be accessed over the network) containing information about potentially 100,000-1,000,000 (or more) objects.
Much of that information will be of a quasi-boolean character: "is it an X or not?" for various choices of X, but with "yes", "no", "borderline", and "not yet evaluated" as the four possible values. It will be desirable to query for these, for example to get a lazy seq of all objects for which it's a borderline Y or for which it's not yet evaluated whether it's a Z or for which it's either "yes" or "borderline" on whether it's an X or whatever. I'm not that familiar with the local-DB solutions out there. I'd like a recommendation for one which is a) a good for for Clojure use and b) a good fit for the type of data and queries noted above. The DB must be able to grow larger then available RAM without crashing the JVM and the seqs resulting from queries like the above will also need to be able to get bigger than RAM. My own research suggests that H2 may be a good choice, but it's a standard SQL/relational DB and I'm not 100% sure that fits well with the type of data and querying noted above. Note though that not all querying will take that form; there'll also be strings, uuids, dates, and other such field types and the need to query on these and to join on some of them; also, to do less-than comparisons on dates. Also, what is the current best recommendation of clojure library for interfacing to the DB? (Answer might depend on the sort of DB recommended -- standard, object/NoSQL, graph/ontology, etc.) -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
