Database Table Size

    I have a database table where every 10(ish) seconds I update the entry with the uptime of the system.

    Problem is, is that the size of the table increases slightly every time I update the entry. And over a period of time the size of the table gets large. E.g. I after running over the weekend the table was 5MB in size and when I compacted it it went back down to 100KB. there is only one row in the table.

    Is there anyway I can prevent the size from increasing without using compact?

    I'm using Mckoi database as an embedded db in a java (1.4) appliation.

    Do you need to store all those entrys or just need the most upto date one ?

    I only have one entry in the table with a couple of columns and I update the uptime column periodically. The rest of the table stays the same.
    I don't actually add new entries I just update what is already there.

    If you're doing an update on a single row that starts out at 100k and has nothing but a few fields changing, hitting 5mb, then you have a db error.

    Try sqlite or tbh, if all this db is doing is logging uptime, try a flat file, ffs.

    K thanks I'll look into it.

    that's only one part of my db. that's only one table.
    It does a lot more than just storing uptime .
