Subject [jira] [Created] (JCLOUDS-459) Limit number of user threads
Date Mon, 10 Feb 2014 18:38:19 GMT
Andrew Gaul created JCLOUDS-459:
-----------------------------------

             Summary: Limit number of user threads
                 Key: JCLOUDS-459
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-459
             Project: jclouds
          Issue Type: Improvement
          Components: jclouds-core
    Affects Versions: 1.7.1
            Reporter: Andrew Gaul


Presently jclouds does not limit the number of user threads.  While de-asyncification could
address this in the long-term, in the short-term we should protect our users with some sane
default.  I suggest 20 or 50, the former mirroring the number of IO threads, and the latter
sourced from my extensive testing of most blobstore providers.  Note that Atmos providers
have issues with large numbers of concurrent requests and errors from JCLOUDS-137 will occur.
 I work around these in my application by setting 10 IO and 10 user threads for Atmos Online
and 8 and 8 for Synaptic Atmos.
