Description
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.
