UDB_Prefetch_Size (String property)

Defines the number of PageSize pages to read from the tablespace when performing data prefetching. You can also define the prefetch size value as an integer value followed by K (for kilobytes), M (for megabytes), or G (for gigabytes). If you define the property in this way, the floor of the number of bytes divided by the pagesize is used to determine the number of pages value for prefetch size. Prefetching reads in the necessary data for a query before it is referenced by the query. The result is that the query does not need to wait for the I/O to be performed on it.
