content	%META:TOPICPARENT{name="VirtTipsAndTricksGuide"}% ---+How to configure Sponger to use Asynchronous Query (AQ) threads? ---++What? Configuring the number of AQ threads used by the Sponger. ---++Why? Cache invalidation is affected by the number of AQ threads allocated to the Sponger. It also affects the number of concurrent tasked handled by a Sponger instance. ---++How? There is a <code>AsyncQueue = 1/0</code> in the SPARQL section of the virtuoso ini file. This is obsolete. Infact the AQ only is used to protect cache from bad data Steps: 1 [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtTipsAndTricksGuideSPARQLEndpointProtection][Ensure your SPARQL Endpoint is protected]] 1 Configure the Sponger uses AQ by enabling it via the Virtuoso instance INI file <verbatim> # virtuoso.ini ... [SPARQL] ... AsyncQueue = 1 ... </verbatim> ---++Related * [[VirtTipsAndTricksGuide][Virtuoso Tips and Tricks Collection]] * [[http://docs.openlinksw.com/virtuoso/rdfsparql.html][Virtuoso Documentation]] * [[VirtSponger][Virtuoso Sponger]]
