Subject [jira] [Commented] (SOLR-6806) Reduce the size of the main Solr binary download
Date Sun, 22 Feb 2015 17:36:12 GMT


Alexandre Rafalovitch commented on SOLR-6806:

>From the things that could be removed (I think):
Solr ships with lucene-test library (and junit, ant, etc) in dist/test-framework. That's another
10Mb. I don't think anything in the binary distribution actually relies on it.

>             Project: Solr
>          Issue Type: Task

> There has been a lot of recent discussion about how large the Solr download is, and how
to reduce its size.  The last release (4.10.2) weighs in at 143MB for the tar and 149MB for
the zip.
> Most users do not need the full download.  They may never need contrib features, or they
may only need one or two, with DIH being the most likely choice.  They could likely get by
with a download that's less than 40 MB.
> Our primary competition has a 29MB zip download for the release that's current right
now, and not too long ago, that was about 20MB.  I didn't look very deep, but any additional
features that might be available for download were not immediately apparent on their website.
 I'm sure they exist, but I would guess that most users never need those features, so most
users never even see them.
> Solr, by contrast, has everything included ... a "kitchen sink" approach. Once you get
past the long download time and fire up the example, you're presented with configs that include
features you're likely to never use.
> Although this offers maximum flexibility, I think it also serves to cause confusion in
a new user.
> A much better option would be to create a core download that includes only a minimum
set of features, probably just the war, the example servlet container, and an example config
that only uses the functionality present in the war.  We can create additional downloads that
offer additional functionality and configs ... DIH would be a very small addon that would
likely be downloaded frequently.
> SOLR-5103 describes a plugin infrastructure which would make it very easy to offer a
small core download and then let the user download additional functionality using scripts
or the UI.
