    STSdb for Java

    Are there any chances to see STSdb implemented in Java? Probably you know that Java programmers are much more than C# programmers?

    A significant improvement of STSdb

    Viewing/editing the content of a STSdb table in a table editor or DataGridView is too complex now if the table is big, because STSdb does not support access to a specific key/value pair by its...

    I'm afraid STSdb4 has serious flaws

    Gentlemen, it seems that STSdb4.0 has serious flaws! Have you tried to call ITable.Count() function? When I did so, the database started to grow. It became almost twice bigger (from less than 3GB to...

    Yes, you are right - with random keys 3.5 makes larger files, but with ordered keys 4.0 makes larger files. More than 50% larger. Can you bring this percent down to 10 or 15 ?

    Blaze's method is good

    Blaze's approach is useful. Array.Reverse and AddLeadingNulls help making small files and with good speed. 6,840,000 string keys (average length 10 bytes) result in 43 MB file.

    I think you could easily make STSdb excellent with string keys

    I'm afraid StringKeyMap doesn't help much. STSdb is still great with integer keys, but is not practically useful with string keys. When keys are 100,000 the string keys file is only 1.6 times bigger,...

    String keys

    I'm a big fan of STSdb. But I can use it only with integer keys. String keys generate 70 times bigger files (with the same integer keys converted to strings). Why is that?
