What kind of incorrect results it can deliver? For me its okay to live with 
possibility of broken faceting because i do not use that feature.

could not you do same thing as Elastic Search. Build index with number of 
shards (initial number is 5). If there is 1 machine in cluster, then all shards 
are on this machine. If you add more machines, they will move to other 
machines. It is way simple for administration.

Yes, i had similar issue with nutch project. Markus Jelsma reuploaded my patch 
back to JIRA and refused to delete it. Its still in JIRA violating my copyright 
laws. I decided not to escalate the conflict and go after ASF and harm other 
projects just because of misbehavior of one person.

> I've been doing some experiments with stored fields lately. It is very common

> compression ratio, I've run several tests with different index compression 
> strategies on 100,000 docs from Mike's 1K Wikipedia articles (title and text

[jira] [Created] (LUCENE-4544) possible bug in ConcurrentMergeScheduler.merge(IndexWriter)

2012-11-06 Thread Radim Kolar (JIRA)
Radim Kolar created LUCENE-4544:
---

 Summary: possible bug in 
ConcurrentMergeScheduler.merge(IndexWriter) 
 Key: LUCENE-4544
 URL: https://issues.apache.org/jira/browse/LUCENE-4544
 Project: Lucene - Core
  Issue Type: Bug
  Components: core/other
Affects Versions: 5.0
Reporter: Radim Kolar


from dev list:

¨i suspect that this code is broken. Lines 331 - 343 in 
org.apache.lucene.index.ConcurrentMergeScheduler.merge(IndexWriter)

mergeThreadCount() are currently active merges, they can be at most 
maxThreadCount, maxMergeCount is number of queued merges defaulted with 
maxThreadCount+2 and it can never be lower then maxThreadCount, which means 
that condition in while can never become true.

  synchronized(this) {
long startStallTime = 0;
while (mergeThreadCount() >= 1+maxMergeCount) {
  startStallTime = System.currentTimeMillis();
  if (verbose()) {
message("too many merges; stalling...");
  }
  try {
wait();
  } catch (InterruptedException ie) {
throw new ThreadInterruptedException(ie);
  }
} 

While confusing, I think the code is actually nearly correct... but I
would love to find some simplifications of CMS's logic (it's really
hairy).

It turns out mergeThreadCount() is allowed to go higher than
maxThreadCount; when this happens, Lucene pauses
mergeThreadCount()-maxThreadCount of those merge threads, and resumes
them once threads finish (see updateMergeThreads).  Ie, CMS will
accept up to maxMergeCount merges (and launch threads for them), but
will only allow maxThreadCount of those threads to be running at once.

So what that while loop is doing is preventing more than
maxMergeCount+1 threads from starting, and then pausing the incoming
thread to slow down the rate of segment creation (since merging cannot
keep up).

But ... I think the 1+ is wrong ... it seems like it should just be
mergeThreadCount() >= maxMergeCount().

it can not be made simple by not creating thread for every new segment merge 
but to use standard threadpool + queue scheme? Lot of libraries can do it 
easily.
