Shawn Heisey commented on SOLR-6806:
------------------------------------
A potential baby step is to do something different with docs. I see two good
options:
* Remove the docs from the main download entirely, create a separate
downloadable archive for them. For 6.2, this archive would be about 13MB,
making the main download nearly 10 percent lighter.
* Put the compressed docs archive in the main archive. This wouldn't reduce
the size of the download, but it *WOULD* make the archive extract a LOT faster.
See screenshots that I attached earlier.
I think it's a good idea to do the second option to the licenses directory.
This directory doesn't have as many small files in it as the docs directory,
but it still has a significant impact on main archive extraction speed. These
files need to be in the main archive, but IMHO it's perfectly acceptable to
have them contained in an inner archive.

> 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.
