    [ https://issues.apache.org/jira/browse/SOLR-12605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16563006#comment-16563006 ] 

Cao Manh Dat commented on SOLR-12605:
-------------------------------------

Attached a patch for this ticket. The replacement seems good, tests seem happy with the changes. There are several things should be handled in other issues
* Rolling update is not possible since Http2SolrClient can't talk to old Solr node (because of https://github.com/eclipse/jetty.project/issues/1308). 
* In the past, all the updates are sent in a single stream from the leader, the replica will create a single thread to parse all the updates. For the simplicity of this ticket, the replica will parse updates in different threads.

> This issues will aim to replace the usages of {{StreamingsSolrClients}} and {{ConcurrentUpdateSolrClient}} by {{Http2SolrClient}}. Basically by doing this, the communications between replicas will use http2.
