An AutoFill Keyword Set Number is a unique identifier for an AutoFill Keyword Set. The Keyset Block Size option controls the number of AutoFill Keyword Set Numbers reserved for imported AutoFill Keyword Sets. This can be used with a process that is importing a large quantity of new AutoFill Keyword Sets to increase performance of the import process. By default, when a process creates a new AutoFill Keyword Set, new AutoFill Keyword Set Numbers are retrieved from the database one at a time. When the Keyset Block Size option is set to a higher number, the database query retrieves several AutoFill Keyword Set Numbers at one time. These AutoFill Keyword Set Numbers are cached in memory in the software, which reduces the number of queries against the database when performing import processing.
The database query always retrieves the number of AutoFill Keyword Set Numbers specified by the Keyset Block Size option. Set this option to the average size of the batches you are processing. The range of values available is 1 – 1000. If the process only needs one AutoFill Keyword Set Number but the option is set to 100, 99 AutoFill Keyword Set Numbers are left unused and cannot be reused.
