      As of server version 3.4 (max wire version 5), a collation option is supported for some commands. Helpers for the following commands therefore must be updated:

      • create
      • createIndexes
      • aggregate
      • count
      • distinct
      • find (command only)
      • findAndModify
      • geoNear
      • group
      • mapReduce
      • remove (command)
      • update (command)

      The follow CRUD API methods are thus affected. Supporting a collation option for these methods is required:

      • count
      • distinct
      • find
      • deleteOne
      • deleteMany
      • findOneAndDelete
      • findOneAndReplace
      • findOneAndUpdate
      • replaceOne
      • updateMany
      • updateOne

      Support defining an index as a key pattern

      Creating an index, dropping an index, and providing an index hint will support collations defined as documents.

      Note about bulk writes

      Given the definition of a Bulk Write Model as a document in the form:

      { updateOne: {  filter: {..}, update: {...} } }

      or 

      { deleteOne: {  filter: {..} } }

      etc., a collation can be defined for each bulk write model as in the following example:

      db.collection.bulkWrite([
{updateOne: {..., collation: {...}}},
{updateMany: {..., collation: {...}}},
{replaceOne: {..., collation: {...}}},
{deleteOne: {..., collation: {...}}},
{deleteMany: {..., collation: {...}}}
]);

      The driver must not automatically add a collation to any of the Bulk Write Models; the user must explicitly provide the collation to each.
