Thanks for all this information. It clears lot of confusion surrounding
CDCR feature. Although, I should say that if CDCR functionality is so
fragile in SolrCloud and not worth pursuing much, does it make sense to add
some warning about its possible shortcomings in the documentation?

I had a client who asked a lot about CDCR a few years ago, but I kept
recommending
aginst it and recommended them to go for Ericks’s alternative (2), since they

The biggest issue with CDCR is it’s rather fragile and requires monitoring,
it’s not a “fire and forget” type of functionality. For instance, the use of the
tlogs as a queueing mechanism means that if, for any reason, the communications
between DCs is broken, the tlogs will grow forever until the
Thanks, Jason. This is very helpful.
I should clarify though that I am not using CDCR currently with my

will be relying heavily on the CDCR feature if we migrate from solr
master-slave architecture to solrcloud architectur
Hi Arnold,

compatibility with other
Thanks for this reply, Jason.

Although, I am planning to use Solr 8.3. It has been long time since CDCR
was first introduced. I wonder what is the state of CDCR is 8.3. Is it
stable now?

Hi Arnold,
The stability and complexity issues Mark highlighted in his post
aren't just imagined - there are real, sometimes serious, bugs in
SolrCloud features. But at the same time there are many many stable
deployments out there where SolrCloud is a real success story for
users. Small example

Hi,
I am trying to upgrade my system from Solr master-slave architecture to
SolrCloud architecture.
Meanwhile, I stumbled upon this very negative post about SolrCloud.
