[jira] [Updated] (SOLR-2906) Implement LFU Cache
[ https://issues.apache.org/jira/browse/SOLR-2906?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Erick Erickson updated SOLR-2906: - Attachment: SOLR-2906.patch This should be the final patch. Added the stuff to actually get the parameter from solrconfig timeDecay which ages out the cache entries as we've discussed. Added tests to insure that it gets through from the config file. Shawn: If you'd add some data to the Wiki about this new parameter, that would be a good thing. If nobody objects, I'll probably check this in in the next couple of days. Since they're all new files, the patch will apply to both trunk and 3x cleanly.

Look in the diff for timeDecay. This still needs some proof that the new parameter comes through from a schema file. Let me know if that presents a problem or if you can't get 'round to it, I might have some time over Christmas.

Shawn: Could you add in the optional time decay as Yonik suggests? I agree that it seems like the right thing is to have this on by default. At that point, I think it'll be ready to check in. We can add documentation as we can. We could also check it in as is and raise another JIRA.

Like before, my patch is against branch_3x. Yonik, you may be right about lastAccessed. I was striving for correctness on this first pass, but perhaps it's not worthwhile to care about that too much, just let Java's default functionality figure out which ones to evict.

I'm not wholly convinced that dividing by 4 is the right thing to do here; it'll tend to flatten all the entries making removal somewhat arbitrary as after a few passes anything with hits in the low range will collapse to zero. That said, though, since the little adventure with lastAccessed, all entries with the same number of hits will be treated as LRU so I guess it works.

[ https://issues.apache.org/jira/browse/SOLR-2906?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Shawn Heisey updated SOLR-2906: --- Attachment: SOLR-2906.patch Updated patch. One of the bugs I had to fix was in the least/most items methods, so that I added new items to the TreeSet before removing old ones, because the one it just added might have the same hitcount as entries already present. Without checking the new entry, I couldn't know which entry was the right one to remove. This change reverts it to a remove then add when the hitCounts are different in the right direction. When they are equal, it still does the add before the remove. By reducing the size of the set before adding a new member whenever possible, there is a possibility it can go faster.
