Re: Creating Solr servers dynamically in Multicore folder

[nishwanth]

Hello Erick,

Thanks for the response 

I have attached the core.properties and solr.xml for your reference.

.  solr.xml   
core.properties
  

Below is our plan on the creating cores.

Every Tenant (user) is  bound to some Contacts,sales,Orders and other
information . Numbers of tenants for our application will be approximately
10,000. 

We are planning to create a Core for every Tenant and maintain the
Contacts,sales,Orders and other information as a collection . So every time
Tenant logs in this information will be used.

Could you please let us know your thoughts on this approach.

Regards,
Nishwanth

You should be good to go. Do note that you can the variables that were
defined in your schema.xml in the individual core.properties file for
the core in question if you need to, although the defaults work for
most people's needs.


Best,
Erick

Hello Erick,

Thanks for the response . My cores got created now after removing the
core.properties in this location and the existing core folders . 

Also i commented the core related information on solr.xml . Are there going
to be any further problems with the approach i followed.

For the new cores i created could see the conf,data and core.properties file
getting created.

Thanks..

Re: Creating Solr servers dynamically in Multicore folder

Well, you already have a core.properties file defined in that
location. I presume you're operating in "core discovery" mode. Your
cores would all be very confused if new cores were defined over top of
old cores.

It is a little clumsy at this point in that you have to have a conf
directory in place but _not_ a core.properties file to create a core
like this. Config sets will eventually fix this.

Best,
Erick
