Is it possible to use multiple index data directory in Apache Solr?

[Jou Sung-Shik]

I'm new in Apache Lucene/Solr.

I try to move from Elasticsearch to Apache Solr.

So, I have a question about following index data location configuration.


*in Elasticsearch*

# Can optionally include more than one lo # the locations (a la RAID 0) on
a file l # space on creation. For example:
#
# path.data: /path/to/data1,/path/to/data2

*in Apache Solr*

/var/data/solr/


I want to configure multiple index data directory like Elasticsearch in
Apache Solr.

Is it possible?

How I can reach the goal?

I don't believe this is possible in Solr.

How exactly does ES split the index files when multiple paths are
configured?  I am very curious about exactly how this works.  Google is
not helping me figure it out.  I even grabbed the ES master branch and
wasn't able to trace how path.data is used after it makes it into the
environment.

In truth, for most people I do not really see this feature as all that
much of an advantage.  For best performance, you want to completely
avoid hitting the disk at all -- the index should be entirely cached in
RAM.  When that is achieved, disk performance won't matter.  It could
help in situations where the total index data on a single server is far
too big to ever fit into RAM, or where each disk is small.

Thanks,
Shawn

Re: Getting started with Solr

[Baruch Kogan]

Thanks for bearing with me.

I start Solr with `bin/solr start -e cloud' with 2 nodes. Then I get this:

*Welcome to the SolrCloud example!*


*This interactive session will help you launch a SolrCloud cluster on your
local workstation.*

*To begin, how many Solr nodes would you like to run in your local cluster?
(specify 1-4 nodes) [2] *
*Ok, let's start up 2 Solr nodes for your example SolrCloud cluster.*

*Please enter the port for node1 [8983] *
*8983*
*Please enter the port for node2 [7574] *
*7574*
*Cloning Solr home directory /home/ubuntu/crawler/solr/example/cloud/node1
into /home/ubuntu/crawler/solr/example/cloud/node2*

*Starting up SolrCloud node1 on port 8983 using command:*

*solr start -cloud -s example/cloud/node1/solr -p 8983   *

I then go to http://localhost:8983/solr/admin/cores and get the following:
