NODESIZE

The NODESIZE option specifies the size of the index nodes to use for an indexed file.

Syntax:
NODESIZE={512|1024|4096|16384}
Properties:
Default: The minimum NODESIZE value for the key length, except that for key lengths less than 50 bytes, the default is 1024.

Use the following minimum NODESIZE values depending on the length of your keys:

Key Length in Bytes Minimum NODESIZE Value in Bytes
Less than 51 512
51 through 100 1024
101 through 512 4096
513 through 4080 16384
Comments:

In most circumstances you should allow the File Handler to work out the appropriate default node size. However, if file size is an issue, smaller node sizes do result in a smaller index file, but you should be aware that they also increase processing time as the tree depth is greater.
