Noble Paul updated SOLR-13637:
------------------------------
Description:
When we update jars or add/modify plugins no core reloading should be required
.Core reloading is a very expensive operation. Optionally, we can just make the
plugin depend on the corecontainer level classloader.
{code:xml}
<queryParser name="mycustomQParser" class="my.path.to.ClassName"
runtimeLib="global">
</queryParser>
{code}
The global classloader is the corecontainer level classloader . So whenever
this is reloaded The component gets reloaded. The only caveat is, this
component cannot use core specific jars
eg:
{code}
curl -X POST -H 'Content-type:application/json' --data-binary '
{
"update-runtimelib": {
"name": "lib-name" ,
"url" : "http://host:port/url/of/jar";,
"sha512":"<the-new-sha512>"
}
}' http://localhost:8983/api/cluster
{code}
