The CacheSize property sets or returns a long value that specifies the number of records that can be cached locally in memory. The value must be greater than 0.
Note: You can change this property any time, as long as the Recordset exists, but remember that the cached content will not change until the next retrieval from the database.
The default value for this property is 1. This means that only one record is fetched and cached at a time. For large databases, this is not efficient. A larger value will speed up operations, but remember that cached records may not show recent changes made to the database. To avoid this you can call the Resync method regularly, which will update the cache.
