dump and load a db containing the lucene design doc

[Nitin Borwankar <ni...@borwankar.com>]

Hi guys,

I have a database that has a design document that triggers couchdb-lucene
indexing  ( the exact name slips my mind ).
If I dump the db and load it into a different db on same couch installation
- the new db now has the doc that triggers lucene indexing - but when does t
the lucene indexing actually happen - on load?  On first lucene query ?

Note I am asking about lucene's indexing not couchdb's

Nitin,

couchdb-lucene indexes databases asynchronously which means, "shortly
after the design doc shows up, but not at a deterministic boundary
like doc insert or first query. Last I heard Robert talking, he was
either going to (or has already) implemented the familiar "Every N
docs or M seconds" scheme, so it should be configurable either way.

Hi Nitin, I believe it will start indexing as soon as the _design/ 
lucene document shows up in the new DB, but there's a sorting phase  
that imposes a first query hit.

As an aside, why not just do a local->local replication here?  It'll  
be substantially faster than dumping and loading since there's no JSON  
overhead.  Best,

Adam
