This is a java/scala solr client providing an interface like SolrJ, just asynchronously / non-blocking (built on top of async-http-client / netty).

Key Features

  • Async, non-blocking API to Solr on the JVM: supports CompletableFuture for Java, for Scala you can choose between Twitter's Future or the standard/SDK Future.
  • SolrCloud support
  • Optimized request routing (e.g. updates go to leaders, _route_ param is respected, replica.type is supported for shards.preference param)
  • Pluggable load balancing strategies, comes with a performance/statistics based load balancer
  • Support for retry policies in case of failures
