Cache

Default Fetch Size

Starting with Denodo 5.5, the default fetch size when retrieving data from the cache data source is now set to 1,000. In Denodo 4.7 and earlier, it is 10.

In most cases, the data is retrieved much faster with a fetch size of 1,000. However, when the number of rows is small but very big, we recommend testing if this value meets your performance needs. Rows are big when they contain several fields of type blob that occupy several megabytes. This can happen when the blob fields contain big pictures, long PDF documents, etc.
