Henri Biestro commented on SOLR-350:
------------------------------------
On aliases - for completeness - , I had this "nagging" thought I was missing
something...
Re-reading Hoss's proposal and crossing that with the 1000 unique names point
you made, there is in any case 1000 unique 'instanceDir' that need to be
provided; Hoss proposed to use the 'instanceDir' instead of a name and alias
that if I'm not mistaken.
I got side tracked by the fact that the instanceDir could be absolute which
would have introduced a deployment host 'hard' dependency and lost the
equivalence.
If we define an 'instanceRoot' (at the multicore level or at the core level)
and make the (core) instanceDir = instanceRoot + '/' + name, the uniqueness of
the core name would be put to its initial intended use (instead of just being a
by-product of the alias feature). In that case, at least one alias is
convenient so we can keep the 'url' constant across index revisions.
For instance, if you are using svn, you could have you instanceDir/{schema,
conf} versioned; when you have a new revision ready to go, you copy these over
using the instanceDir+","+revision-number and use that as a name (which isn't
too bad of a convention).
And then, there are maybe future features that could be added to use aliases
for other purpose...
Oh well...
