Subject: Am I missing something ?<br>To: infinispan -Dev List <<a href="mailto:infinispan-dev@lists.jboss.org">infinispan-dev@lists.jboss.org</a>><br><br><br>Hi All,<div><br></div><div>just a quick question.. what could motivate Infinispan to check my store *each* time I get an entry from the its cache ??</div>
<div><br></div><div>While I was debugging the BlobCacheStore I noticed that all my 'get' endend up in a decompression of an entry downloaded from S3...</div>
<div><br></div><div>Did I miss somthing in my config ?:</div><div><br></div><div>1) jgroups as transport</div><div>2) jmx enabled</div><div>3) transaction enabled (Atomikos)</div><div>4) distribution mode</div><div>5) l1 enabled</div>
<div>6) two owners (actually only one alive... does this have an impact ?)</div><div>7) no passivation </div><div>8) cache is shared</div><div>9) cache is no preloaded </div><div>10) then the config for the cache store</div>
<div>11) eviction manual (my own)</div><div>12) one minute max locking</div><div><br></div><div>And *each* time I 'get' something from the cache... it goes to the store.</div><div><br></div><div>I must be missing something ;-)</div>
