The blocking property controls the behavior of the SQL table logger when its internal buffer is full. The default value is true, which means that the data source feeding the SQL table logger blocks until there is room in the buffer. Use this setting in conjunction with a DataListenerQueue. See Data Collector Queues in this chapter and Queues in the Core Oracle Commerce Platform Services chapter for more information about using queue components.

If you are not using a DataCollectorQueue and do not want your data source to block, set blocking to false. This is not recommended, however, as it causes new data to be lost when the internal buffer is full.
