-----------------------------------
Summary: look at reducing depencies for lucene/replicator
Key: LUCENE-9851
URL: https://issues.apache.org/jira/browse/LUCENE-9851
Project: Lucene - Core
Issue Type: Wish
Reporter: Robert Muir
Lucene/replicator brings in a lot of dependencies (some test-only) for http
communication (httpclient, jetty, servet-api, etc), I think it is worth looking
at reducing these.
It isn't gonna need to be used as a typical high-qps webserver, instead low
level transfer of index segments. IMO this is a more delicate operation where
we actually care about stuff like how/if data is compressed and want it done
efficiently.
I've had good experiences in production with java 11's new http client:
https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/package-summary.html
It is maintained by openjdk and built into java's core, so we could remove the
httpclient dependency and not cause conflicts with downstream projects.
On the server side I think jetty may be overkill, we could use jdk's built-in
Http/HttpsServer, too. Because we don't need fancy nonblocking io / resource
pooling / whatever, its smaller number but MUCH BIGGER than average http
transfers going on.
We can keep replicators apis generic so that users can still use different
protocols or methods, this is really just about the *implementations* and
*tests* that we supply.
