Re: Lucene upgrade
Usually re-creating region and index are expensive and customers are reluctant to do it, according to my memory. We do have an offline reindex scripts or steps (written by Barry?). If that could be an option, they can try that offline tool. I saw from Mario's email, he said: "I didn't found a way to write lucene in older format. They only support reading old format indexes with newer version by using lucene-backward- codec." That's why I think option-1 is not feasible. Option-2 will cause the queue to be filled. But usually customer will hold on, silence or reduce their business throughput when doing rolling upgrade. I wonder if it's a reasonable assumption. Overall, after compared all the 3 options, I still think option-2 is the best bet.

Re: bug fix needed for release/1.11.0
+1 to cherry-picking the fix. The sha hasn't made it to benchmarks yet due to an issue with CI losing resource refs that were needed to keep it moving through the pipeline. The next commit is still about an hour away from triggering benchmarks. In my manual benchmarking of this change, I found that it resolved the issue with SSL and passed the benchmarks. Obviously we still need to confirm that it works through the main pipeline, but I feel confident that it will pass the benchmark job.

Re: Lucene upgrade
Dan - LGTM check it in! ;-) (kidding of course) Jake - there is a side effect to this in that the user would have to reimport all their data into the user defined region too. Client apps would also have to know which of the regions to put into.. also, I may be misunderstanding this suggestion, completely.

Yeah, I didn’t explain well. I mean to say literally create a new region for the new version of lucene and effectively start over. Yes this is expensive but its also functional. So new members would create region `lucene-whatever-v8` and start over there. Then when all nodes are upgraded the old `lucent-whatever` region could be deleted.

Elaborating on this option a little more, this might be as simple as
something like the below at the beginning of LuceneEventListener.process.
Maybe there is a better way to cache/check whether there are old members.
The danger with this approach is that the queues will grow until the
upgrade is complete. But maybe that is the only way to successfully do a
rolling upgrade with lucene indexes.
boolean hasOldMember = cache.getMembers().stream()
.map(InternalDistributedMember.class::cast)
.map(InternalDistributedMember::getVersionObject)
.anyMatch(version -> version.compareTo(Version.GEODE_1_11_0) <0);
if(hasOldMember) {
return false;
}

Re: Lucene upgrade
Jake, -from my understanding, the implementation details of geode-lucene is that we are using a partitioned region as a "file-system" for lucene files. As new servers are rolled, the issue is that the new servers have the new codec. As puts occur on the users data region, the async listeners are processing on new/old servers alike. If a new server writes using the new codec, it's written into the partitioned region but if an old server with the old codec needs to read that file, it will blow up because it doesn't know about the new codec. Option 1 is to not have the new servers process/write if it detects different geode systems (pre-codec changes). Option 2 is similar but requires users to pause the aeq/lucene listeners Deleting the indexes and recreating them can be quite expensive. Mostly due to tombstone creation when creating a new lucene index, but could be considered Option 3. It also would probably require https://issues.apache.org/jira/browse/GEODE-3924 to be completed. Gester - I may be wrong but I think option 1 is still doable. We just need to not write using the new codec until after all servers are upgraded. There was also some upgrade challenge with scoring from what I remember, but that's a different topic...

Re: Lucene upgrade
He tried to upgrade lucene version from current 6.6.4 to 8.2. There're some challenges. One challenge is the codec changed, which caused the format of index is also changed. That's why we did not implement it. If he resolved the coding challenges, then rolling upgrade will probably need option-2 to workaround it.

Re: Lucene upgrade
What about “versioning” the region that backs the indexes? Old servers with old license would continue to read/write to old region. New servers would start re-indexing with the new version. Given the async nature of the indexing would the mismatch in indexing for some period of time have an impact? Not an ideal solution but it’s something. In my previous life we just deleted the indexes and rebuilt them on upgrade but that was specific to our application. -Jake > On Nov 6, 2019, at 11:18 AM, Jason Huynh wrote: > > Hi Mario, > > I think there are a few ways to accomplish what Dan was suggesting...Dan or > other's, please chime in with more options/solutions. > > 1.)

Re: Lucene upgrade
Hi Mario, I think there are a few ways to accomplish what Dan was suggesting...Dan or other's, please chime in with more options/solutions. 1.) We add some product code/lucene listener to detect whether we have old versions of geode and if so, do not write to lucene on the newly updated node until all versions are up to date. 2.) We document it and provide instructions (and a way) to pause lucene indexing before someone attempts to do a rolling upgrade. I'd prefer option 1 or some other robust solution, because I think option 2 has many possible issues. -Jason On Wed, Nov 6, 2019 at 1:03 AM Mario Kevo wrote: > Hi Dan, > > thanks for suggestions. > I didn't found a way to write lucene in older format.

IncrementalBackupDistributedTest.testMissingMemberInBaseline hangs
IncrementalBackupDistributedTest.testMissingMemberInBaseline is hanging intermittently in the DistributedTest job of CI and precheckin. I filed GEODE-7411 with all the involved thread stacks that I could find: https://issues.apache.org/jira/browse/GEODE-7411 If anyone knows of any recent changes to backups, diskstore locking, or the locking of diskstores during cache close, please let Mark or I know.

Re: Lucene upgrade
Hi Dan, thanks for suggestions. I didn't found a way to write lucene in older format. They only support reading old format indexes with newer version by using lucene-backward- codec. Regarding to freeze writes to the lucene index, that means that we need to start locators and servers, create lucene index on the server, roll it to current and then do puts. In this case tests passed. Is it ok?
