Re: Solr High Availability | Multi-Datacenter approach

Hi, We're facing similar situations. If "run multiple fully independent clusters" is the recommended solution, is there any recommended way to do disaster recovery during query time? In our production environment, we're using solrj as the client. What comes to my mind is declaring two client inst

Re: Is there an easy way to determine Lucene versions for segments?

That’s what we are planning on doing. Block writes(making index read-only), write into a parallel directory using 8.x lucene codec and then switch over if/when completely written. Downside is (temporarily) requiring double the index size in total disk space while writing the index given that we reg

Hi all, Any update on this please , What was the intention was stall prevention logic ? If a replica is not able to recover from leader unless it's restarted then isn't it a bug ? On Wed, Sep 29, 2021, 9:03 PM dinesh naik wrote: > Dear all, > I have seen replica not recovering issue in both s

Won’t work. I have tried optimize on 7.7.2 to 8.x where several segments were originally written in 5.x and 6.x. We are scratching our heads to achieve this seamlessly since reindexing will take several weeks given the size of indexes for many of our customers. -Rahul On Thu, Oct 7, 2021 at 8:35

No, worst case is it closes the index writer and leaves the drive full. 20k free space remaining. On 10/6/21 1:56 PM, Dave wrote: It’s ok. Worst case it just fails and kills the temporary index after you run out of space. Really optimize is almost not even supported (it still works) but a ful
