Does SolrCloud's notion of a "collection", which appears to use cores, override normal multi-core usage for building an offline index and quickly swapping it into production?
A collection will normally be composed of multiple cores. By default right now, a cores name is the collection name, but that's mainly for simplifying basic demo bootstrap type situations. You can fire up two instances of Solr and by default you will have two cores that are part of collection1.
Some of the features in SolrCloud look useful, if it's still possible to exert manual control over cores and shards.
To my knowledge you don't lose any control. You only gain features.
Are there plans to merge the cloud branch into trunk, and if so, will this happen before 1.5 comes out?
Things like this are hard to predict. It would be nice to get more people trying out SolrCloud so that its a bit more battle tested.
I get the impression that version 1.4 is being quickly left in the dust by the 1.5 development effort.
Isn't that always the case ;)
As far as I can tell nobody is trying to even put a ballpark on when 1.5 will be frozen or released. Is it recommended at this point to use 1.5 from trunk over 1.4?
Always a personal decision. A lot of people used 1.4 trunk. We try to keep trunk fairly stable.
Is there a 1.4.1 coming soon that fixes the known bugs?
Do we have a lot of bugs at this point? I have not really payed attention. If so, perhaps we should consider a 1.4.1 soon.
From what I've read so far, it seems that it should be possible to hardlink the contents of the index directory to another core, add/update records, optionally re-optimize it, warm it, and then swap it into production. Is this accurate?
Yeah, this is doable - but Solr already does that for you does it not? While you add update documents, a point in time Searcher is still serving requests. You can also add warming queries that will warm a new Searcher while the old one is still serving queries, and its swapped in when its ready.
A minor thing - is there any way to make Thunderbird 3 stop turning sequences of a caret followed by a number into nice-looking exponents? For weeks I've been wondering what everyone meant by putting exponents in their config descriptions, then the other day I got a look at the actual text of a message and the light went on.
I use thunderbird 3, but I can't say I've noticed this yet.
Thanks, Shawn
