Mikhail Khludnev commented on SOLR-3076:
----------------------------------------
Yonik,
What's your vision of indexing blocks in Solr?
# I guess we need to introduce new method UpdateHandler.addBlock() and
AddBlockCommand as well.
# I suppose we have two different approaches for supporting blocks in
ContentStreamLoader descendants.
** we can introduce new tag in input xml format <docs>...</docs> or
<block>...<block>
** we can transfer List<SolrInputDoc>[] <in javabin format
** the different strategy should be used for plain csv format: we need to add
block separator init parameter in solrconfig.xml eg <str
name="block.separator">type:resume</str>
* as an alternative for all these above we can have just an
UpdateRequestProcessor descendant which separates blocks by employing the same
block.separator approach, in this case update handler support is required
anyway, but it's really little efforts and less invasive.
WDYT?
