Berkeley DB would be the best choice probably but I can't use it due to licensing issues. Are there any alternatives? Fuad Malikov You can try Hazelcast . Just add hazelcast.jar to your classpath. And start coding java.util.Map map = Hazelcast.getMap("myMap"); You'll get an in-memory, distributed, dynamically scalable data grid which performs super fast. Your question could mean one of two things. If you mean a data structure for storing key-value pairs, use one of the Map instances that are a standard part of the JDK. If however you are after an in-memory key-value store then I would suggest

According to the Python 2.6.5 docs [1], the bsddb module has been deprecated for removal in Python 3.0. What module/wrapper should I be using instead? [1] http://docs.python.org/library/bsddb.html I recommend pyBSDdb (from which the version currently in Python standard's library was taken -- but the stand-alone project is more actively maintained and far from deprecated;-). 来源： https://stackoverflow.com/questions/2597068

Problem Following up on this question , it seems that a file- or disk-based Map implementation may be the right solution to the problems I mentioned there. Short version: Right now, I have a Map implemented as a ConcurrentHashMap . Entries are added to it continually, at a fairly fixed rate. Details on this later. Eventually, no matter what, this means the JVM runs out of heap space. At work, it was (strongly) suggested that I solve this problem using SQLite, but after asking that previous question, I don't think that a database is the right tool for this job. So - let me know if this sounds

I'm looking for a dbm-like library that I can use in place of Berkeley DB, which I'm currently using. My main reason for switching is the licensing fees for BDB are pretty high (free for open source apps, but my employer does not want to open source this particular app for various reasons). I've looked briefly at qdbm but it doesn't look like it will fill my needs -- lots of keys (several million) and large data items (> 1-5 megabytes). Before I continue my search I figured I'd ask because it seems there are tons of dbm-like libraries out there. Simon Schmidt C/C++ http://sphia.org/ a Key

How do I fix this without giving up and installing

I'm trying to access "cert8.db" mozilla file which is a BDB database. I know that there are bindings for languages, Java among them, but I'm trying to build a multiplatform app so I think that using JNI such as this one would be a problem. Thanks in advance. You don't need full BDB package to read that file.
