Subject RE: Atomic updates to increase single field bulk updates?
Date Thu, 16 Feb 2017 22:58:26 GMT

: partial update or a complete document. Under the hood a partial update 
: is a complete object anyway. Using partial updates you gain a little 
: bandwidth at the expense of additional stored fields.

FWIW: once SOLR-5944 lands in a released version, that won't always be 
true -- atomic updates on numeric fields that are docValues="true" and 
nothing else (stored=false, indexed=false) will use updatable docvalues 
under the covers and should be much more efficient then either reindexing 
the entire document, or the default atomic update codepath of re-indexing 
all fields from stored values.
