Allows disk use for blocking sort operations exceeding 100MB memory. (MongoDB 3.2 or higher)
For queries against a sharded collection, allows the command (or subsequent getMore commands) to return partial results, rather than an error, if one or more queried shards are unavailable.
Specify if the cursor is a tailable-await cursor. Requires tailable
to be true
Set the batchSize for the getMoreCommand when iterating over the query results.
return BSON regular expressions as BSONRegExp instances.
the serializer will check if keys are valid.
Specify collation (MongoDB 3.4 or higher) settings for update operation (see 3.4 documentation for available fields).
Comment to apply to the operation.
In server versions pre-4.4, 'comment' must be string. A server error will be thrown if any other type is provided.
In server versions 4.4 and above, 'comment' can be any valid BSON type.
Enable utf8 validation when deserializing BSON documents. Defaults to true.
Specifies the verbosity mode for the explain output.
allow to specify if there what fields we wish to return as unserialized raw buffer.
Tell the query to use specific indexes in the query. Object of indexes to use, {'_id':1}
serialize will not emit undefined fields
note that the driver sets this to false
Map of parameter names and values that can be accessed using $$var (requires MongoDB 5.0).
Sets the limit of documents returned in the query.
The exclusive upper bound for a specific index
The maximum amount of time for the server to wait on new documents to satisfy a tailable cursor query. Requires tailable
and awaitData
to be true
Number of milliseconds to wait before aborting the query.
The inclusive lower bound for a specific index
The server normally times out idle cursors after an inactivity period (10 minutes) to prevent excess memory use. Set this option to prevent that.
Option to enable an optimized code path for queries looking for a particular range of ts
values in the oplog. Requires tailable
to be true.
The fields to return in the query. Object of fields to either include or exclude (one of, not both), {'a':1, 'b': 1}
or {'a': 0, 'b': 0}
when deserializing a Binary will return it as a node.js Buffer instance.
when deserializing a Long will fit it into a Number if it's smaller than 53 bits.
when deserializing will promote BSON values to their Node.js closest equivalent types.
Enabling the raw option will return a Node.js Buffer which is allocated using allocUnsafe API. See this section from the Node.js Docs here for more detail about what "unsafe" refers to in this context. If you need to maintain your own editable clone of the bytes returned for an extended life time of the process, it is recommended you allocate your own buffer and clone the contents:
Specify a read concern and level for the collection. (only MongoDB 3.2 or higher supported)
The preferred read preference (ReadPreference.primary, ReadPreference.primary_preferred, ReadPreference.secondary, ReadPreference.secondary_preferred, ReadPreference.nearest).
Should retry failed writes
If true, returns only the index keys in the resulting documents.
serialize the javascript functions
Specify ClientSession for this command
Determines whether to return the record identifier for each document. If true, adds a field $recordId to the returned documents.
Determines whether to close the cursor after the first batch. Defaults to false.
Set to skip N documents ahead in your query (useful for pagination).
Set to sort the documents coming back from the query. Array of indexes, [['a', 1]]
etc.
Specify if the cursor is tailable.
Specify if the cursor can timeout.
when deserializing a Long return as a BigInt.
