[jira] [Comment Edited] (SOLR-599) Lightweight SolrJ client
[ https://issues.apache.org/jira/browse/SOLR-599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17435849#comment-17435849 ]

-------------------------------------------------------------
I created SOLR-1573 to start modularizing solrj and splitting it in modules. This way solrj-core can be slim with few or no external dependencies (no XML, Zookeeper, Netty etc). Question is what SolrClient impl the {{solrj-core}} module will include. Now that we require JDK11 in 9.0, we can re-visit this idea of a no-dep SolrJ client using JDK's new Http client. That client could be the only supported in solrj-core, and you'd have to add {{solrj-jetty}} in order to get a more capable client for whatever reason, probably solr-core would use the netty client, but simple uses cases in apps would not need it? WDYT?

> Issue Type: Improvement
> Components: clients - java, SolrJ
> Reporter: Shalin Shekhar Mangar
> Priority: Minor
> Fix For: 4.9, 6.0

> SolrJ provides a SolrServer implementation backed by commons-httpclient which introduces many dependency jars (commons-codec, commons-io and commons-logging). Apart from that SolrJ also uses StAX API for XML parsing which introduces dependencies like stax-api, stax and stax-utils.
> This enhancement will add a SolrServer implementation backed by java.net.HttpUrlConnection and will use BinaryResponseParser as the default response parser. Using this basic implementation out of the box would require no dependencies on either commons-httpclient or StAX. The only dependency would be on solr-commons making this a very lightweight and distribution friendly Java client for Solr.
