---+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 This is obsolete.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>
