Robert Muir commented on SOLR-3251:
-----------------------------------
Hi Steve, I took a quick glance. One thing I don't quite understand:
{quote}
SchemaCodecFactory and SchemaSimilarityFactory don't change codec and
similarity when the schema is swapped out: instead they refer to the latest
version they have been inform()'d about.
{quote}
Can you elaborate on this (maybe just some code comments about which inform()
gets called when)? I don't understand why there should be 2 inform methods or
what its doing... ?
Is the idea that these classes just need to be core-aware instead? And the
SchemaAware interface is pretty much useless, except its being used now only as
a marker to detect that the sim/codec understands properties on schema elements?
Can we do something to eliminate the two inform methods?
{quote}
Schema is now effectively immutable: requests see the same schema snapshot for
their lifetimes.
{quote}
well, except it seems for similarity (on indexsearcher)... which could be
looking at the latest copy?
