Hi All, I am testing a SolrCloud with many collections. The version is 5.2.1
and I installed 3 machines – each one with 4 cores and 8 GB Ram.Then I created
collections with 3 shards and replication factor of 2. It gives me 2 cores per
collection on each machine.I reached almost 900 collections and then the
cluster was stuck and I couldn’t revive the cluster. As I understand Solr have
issues with many collections (thousands).If I will use much more machines –
does it will give me the ability to create tens of thousands of collections or
the limit is couple of thousands? I want to build a cluster that will handle 10
billion of documents (currently I have 1 billion) per day and to keep the data
for 90 days.I want to support 2000 customers so I would like to split them to
collections and also to split it by days. (180,000 collections)If I will create
big collections I will have performance issues with queries and also most of
the queries are for a specific customer. (I also have cross customers queries)
How I can build an appropriate design? Thanks a lot,Yuri
