Jack Krupansky commented on LUCENE-4258:
----------------------------------------
It would be nice to have the feature description incorporated right here in the
Jira itself. At least a concise summary of what it will do, how it will do it,
and an example or two of how it would be used. Solr "atomic update" has an
"increment" feature for numeric fields as well as an "add" for multivalued
fields - does that proposal include (or at least be compatible with) those
extensions as well? I mean, it would be nice if Solr could switch over to this
approach, if possible. Of course, that begs the question of how this proposal
would "stack up" against the technique that Solr uses today for incremental
field update.
Also, it sounds like this is more of a 5.0 feature, even if maybe it does
eventually make it into some future 4.x release as well. I mean, 4.4 is
expected within the next few weeks, right? While this feature sounds like it
will require a lot of testing and baking to be ready for prime time.
It sounds like it has an assignee, as well. Or, does that have to be a
committer.
