Ishan Chattopadhyaya commented on SOLR-14022:
---------------------------------------------

I think we should *remove it now* (deprecate in 8.4, remove from master), 
because current design is totally unsuitable for any production system.
Having this half baked system is detrimental for Solr's usability and hence its 
image.

We should rebuild it with a fresh perspective, and in a pluggable manner. Some 
alternatives that come to mind (we can use combination of these or any of 
these):
# Approach 1: Primary cluster sends documents to Kafka, secondary cluster picks 
up from there. Much more reliable than Solr doing everything by itself.
# Approach 2: Similar to TLOG/PULL replicas, secondary cluster pulls segments 
from primary cluster upon commits.
