Need Support - Apache Solr - 20180914

[senthil <se...@sardonyx.in>]

Dear Team,

 

We need the below clarifications and doubts in the "Apache Solr" and please
give us the solution. 

 

1.      Apache Solr is the Database or not ?

 

2.      The limitation for Apache Solr is 2 billion records and how can we
increase it (unlimitted) ?

 

3.      How many users can use / access Apache Solr through web application
at a time ?

 

 

 

Thanks & Regards

Solr is a search index.  It is not database software.  In the broadest 
terms, you could CALL the on-disk binary representation a database, but 
Solr is not designed to fill a data storage role.

Run SolrCloud and use a sharded index.  The limit will increase 
depending on the number of shards.  If you have two shards, the index 
will be limited to a little over 4 billion documents.

This limit is not in Solr, it is in Lucene, which is the search library 
that provides most of Solr's functionality.

There is no hard limit.  What Solr can handle will depend on the 
available system resources.  If you have an extremely high query rate, 
then you need many copies of your index and a way to balance your 
queries across those copies.  SolrCloud itself provides load balancing, 
but there are still situations even with SolrCloud where you will need a 
separate load balancer.

One final thought: This mailing list is not appropriate for these 
questions.  This list is for discussion about the development of Lucene 
and Solr.  Your question belongs on the solr-user mailing list.

Thanks,
Shawn
