-----------------------------------
Summary: Improve Aliases.java and comma delimited collection list
handling
Key: SOLR-11444
URL: https://issues.apache.org/jira/browse/SOLR-11444
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Reporter: David Smiley
Assignee: David Smiley
While starting to look at SOLR-11299 I noticed some brittleness in assumptions
about Strings that refer to a collection. Sometimes they are in fact
references to comma separated lists, which appears was added with the
introduction of collection aliases (an alias can refer to a comma delimited
list). So Java's type system kind of goes out the window when we do this. In
one case this leads to a bug -- CloudSolrClient will throw an NPE if you try to
write to such an alias. Sending an update via HTTP will allow it and send it
to the first in the list.
So this issue is about refactoring and some little improvements pertaining to
Aliases.java plus certain key spots that deal with collection references. I
don't think I want to go as far as changing the public SolrJ API except to
adding documentation on what's possible.
