Two Secondary Partitions
You can use a shortcut if you need only two secondary partitions. The first 12 bytes of
the key can be used to partition the file. You need supply only your node number.
The numbers of the key are as follows:
[ 192, 0, 168, 235, 0, xx, 84, 32, 32, 32, 0, 1 ]
[ 192, 0, 168, 235, 0, xx, 84, 32, 32, 32, 0, 2 ]
with xx being your node number.
The second partition needs to be approximately twice the size of the other partitions.
This larger partition is used by the asynchronous processes where the high volume of
activity causes the file to grow faster than the other partitions do.
Example of a File with Two Secondary Partitions
Here is an example of the short method to get two secondary partitions.
