embedded-database

I need a fast, reliable and memory-efficient key--value database for Linux. My keys are about 128 bytes, and the maximum value size can be 128K or 256K. The database subsystem shouldn't use more than about 1 MB of RAM. The total database size is 20G (!), but only a small random fraction of the data is accessed at a time. If necessary, I can move some data blobs out of the database (to regular files), so the size gets down to 2 GB maximum. The database must survive a system crash without any loss in recently unmodified data. I'll have about 100 times more reads than writes. It is a plus if it

One thing I love about .NET is the ability to have a database file along with the project. I know that using a SQLite database, this can be done, but did someone achieve this with a MySQL database backend? So for instance, if I run a java program, it should be able to start its own mini MySQL server and manipulate data. So essentially, I want the same flow as with a SQLite but I need the power of MySQL. A quick search shows this: MySQL Connector/MXJ — for embedding MySQL server in Java applications on the MySQL Downloads page at: http://dev.mysql.com/downloads/ If you don't mind using MariaDB

i am not clear about steps/configuration details about how i can embed mysql in a Java desktop application so that it(application) can be installed on any machine through a single executable file and doing so sets up database and also provides an exe to run the app.Till now i have built my app using netbeans and i have used mysql to set up database.plz guide me further. MySQL isn't an embedded database - the only JAR related to it is the JDBC driver. It requires a installation process, which might be able to be scripted via Java, but the process will definitely function outside of the Java

I'm trying to setup an embedded Derby database for a standalone Java application, but after pouring through all sorts of documentation, I just can't seem to find any simple explanations or examples. I'm using Eclipse with the Derby plugin and have enabled Derby nature for my project. I found an example of using an embedded Derby database in a standalone address book as well as an overview of using Derby in Eclipse (that doesn't seem to cover the embedded deployment), but I still feel like I'm missing something fundamental. This is my first time attempting to use a database with Java, and I'm a

My question is I think quite simple but I don't think the answer will be... I have quite a lot of content to have in my application to make it run properly, and I'm thinking of putting all of it in a database, and distribute it in an embeded database with the application in the market. The only trouble is that I have no idea of how to do that. I know that I can extract a file .db from Eclipse DDMS with the content of my database, and I suppose I need to put it in the asset folder of my application, but then how to make the application use it to regenerate the application database? If you have

I am creating an in memory database in H2 database by the following code on servlet context startup void initDb() { try { webserver = Server.createWebServer().start(); Class.forName("org.h2.Driver"); Connection conn = DriverManager.getConnection("jdbc:h2:mem:db1;DB_CLOSE_DELAY=-1","SA",""); InputStream in = getClass().getResourceAsStream("script.sql"); if (in == null) { System.out.println("Please add the file script.sql to the classpath, package " + getClass().getPackage().getName()); } else { RunScript.execute(conn, new InputStreamReader(in)); Statement stat = conn.createStatement();

What does your Spring configuration for integration tests look like using an embedded h2 datasource and, optionally, JUnit? My first try with a SingleConnectionDataSource basically worked, but failed on more complicated tests where you need several connections at the same time or suspended transactions. I think h2 in tcp based server mode might work as well, but this is probably not the fastest communication mode for a temporary embedded database in memory. What are the possibilities and their advantages / disadvantages? Also, how do you create the tables / populate the database? Update: Let's
