Synopsis

Description
These flags correspond to the MongoDB wire protocol. They may be bitwise or'd together. They may modify how a query is performed in the MongoDB server.
Flag Values
MONGOC_QUERY_NONE |
Specify no query flags. |
MONGOC_QUERY_TAILABLE_CURSOR |
Cursor will not be closed when the last data is retrieved. You can resume this cursor later. |
MONGOC_QUERY_SLAVE_OK |
Allow query of replica set secondaries. |
MONGOC_QUERY_OPLOG_REPLAY |
Used internally by MongoDB. |
MONGOC_QUERY_NO_CURSOR_TIMEOUT |
The server normally times out an idle cursor after an inactivity period (10 minutes). This prevents that. |
MONGOC_QUERY_AWAIT_DATA |
Use with MONGOC_QUERY_TAILABLE_CURSOR. Block rather than returning no data. After a period, time out. |
MONGOC_QUERY_EXHAUST |
Stream the data down full blast in multiple "reply" packets. Faster when you are pulling down a lot of data and you know you want to retrieve it all. |
MONGOC_QUERY_PARTIAL |
Get partial results from mongos if some shards are down (instead of throwing an error). |
