Async batch indexing to Solr

[Almog Tavor <al...@gmail.com>]

Hi,
I'd like to perform asynchronous bulk indexing operations to Solr with Java.
I've read in the documentation
<https://solr.apache.org/guide/8_7/using-solrj.html>that the Http2SolrClient
<https://solr.apache.org/docs/8_7_0/solr-solrj/org/apache/solr/client/solrj/impl/Http2SolrClient.html>
is
async and non-blocking, but I couldn't find any example in the subject. I
wonder if there's a function that index documents to Solr and returns a
Future. The only thing I've found that fills my needs is the community's "
solrs <https://inoio.github.io/solrs/usage/adding-data.html>" library that
enables one to index documents in bulk and receive a CompletableFuture. I'd
like to know if Solr really offers such an option either, and if not, then
how does Solr expect users to index documents asynchronously.

Solr doesn’t work like that. It doesn’t have transactions and you can’t get notification of when new data is searchable. Documents are indexed either when there is an explicit commit or an autocommit. “Commit” is really not the right word. It is a batch submit. 

All indexing is asynchronous. Submit the batch and go on with life.

This is especially true with replication (any kind), which you need to be running for fault tolerance.
