[jira] [Created] (SOLR-14763) SolrJ Client Async HTTP/2 Requests
Rishi Sankar created SOLR-14763:
-----------------------------------
Summary: SolrJ Client Async HTTP/2 Requests
Key: SOLR-14763
URL: https://issues.apache.org/jira/browse/SOLR-14763
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrJ
Affects Versions: 8.7
Reporter: Rishi Sankar
In [SOLR-14354|https://issues.apache.org/jira/browse/SOLR-14354], [~caomanhdat] created an API to use Jetty async API to make more thread efficient HttpShardHandler requests. This added public async request APIs to Http2SolrClient and LBHttp2SolrClient. There are a few ways this API can be improved, that I will track in this issue:
1) Using a CompletableFuture-based async API signature, instead of using internal custom interfaces (Cancellable, AsyncListener) - based on [this discussion|[https://lists.apache.org/thread.html/r548f318d9176c84ad1a4ed49ff182eeea9f82f26cb23e372244c8a23%40%3Cdev.lucene.apache.org%3E]].
2) An async API is also useful in other HTTP/2 Solr clients as well, particularly CloudHttp2SolrClient ([SOLR-14675|https://issues.apache.org/jira/browse/SOLR-14675]). I will add a requestAsync method to the SolrClient class, with a default method that initially throws an unsupported operation exception (maybe this can be later updated to use an executor to handle the async request as a default impl). For now, I'll override the default implementation in the Http2SolrClient and CloudHttp2SolrClient.
3) Performance benchmarks
