Tuplesoup is a small easy to use Java based framework for storing and retrieving simple hashes. If you are interested in the design and implementation choices I made, have a look at the following blog posts I made while working on the project.
- Part 1, Introduction
- Part 2, Record index
- Part 3, Index caching
- Part 4, First refactoring
- Part 5, Sorting
Since the last post in this series, I have done some further refactoring as well as added a set of statistic counters that can be polled to look for performance issues in usage patterns. The project is far from done, but I feel that it has reached a maturity that might make it useful for other developers. We have currently been using Tuplesoup for projects in our production environment for more than 3 months now without any stability issues. That being said, use at your own risk!
Let me end this post with a little bit of source code to show you how to actually use Tuplesoup in your own code. This very short completely useless example creates a table, adds a row and retrieves the row again. Hopefully I will soon find the time to write a more detailed piece of code showing some real world usage.
import com.solidosystems.tuplesoup.core.*;
Table table=new Table("test","./");
Row row=new Row("1");
row.put("username","kasperjj");
row.put("floatNumber",3.141592);
table.addRow(row);
row=table.getRow("1");
String username=row.getString("username");
Tuplesoup is available through sourceforge and has been released under the BSD license.
