List of changes

yz_solr.erl

Removed the delete by query so it is not executed on every new document index. The delete by query specifically removes siblings from solr before inserting. If siblings are not used (in the case of using CRDTs, siblings are not exposed to Solr), this delete by query is unecessary.

Changed:

index(Core, Docs, DelOps) ->
    Ops = {struct,
           [{delete, encode_delete(Op)} || Op <- DelOps] ++
               [{add, encode_doc(D)} || D <- Docs]},

To:

index(Core, Docs, _DelOps) ->
    %% BEGIN YZ_PERF_PATCH CODE (removed sibling delete, replace if using siblings)
    Ops = {struct,
           [{add, encode_doc(D)} || D <- Docs]},
    %% END YZ_PERF_PATCH CODE
