(Advanced) Flags to use with Cursors in Collection.find().

awaitData

Source

const static OpQueryFlags awaitData := OpQueryFlags.<ctor>(32, "AwaitData")

Use with TailableCursor. If we are at the end of the data, block for a while rather than returning no data.

exhaust

Source

const static OpQueryFlags exhaust := OpQueryFlags.<ctor>(64, "Exhaust")

Stream the data down full blast in multiple "more" packages. Use when reading all the results of a query.

noCursorTimeout

Source

const static OpQueryFlags noCursorTimeout := ...

The server normally times out idle cursors after an inactivity period (10 minutes) to prevent excess memory use. Set this option to prevent that.

none

Source

const static OpQueryFlags none := OpQueryFlags.<ctor>(0, "None")

No flags are set. Business as usual.

partial

Source

const static OpQueryFlags partial := OpQueryFlags.<ctor>(128, "Partial")

Get partial results from a mongos if some shards are down (instead of throwing an error).

slaveOk

Source

const static OpQueryFlags slaveOk := OpQueryFlags.<ctor>(4, "SlaveOk")

Allow query of replica slave. Normally these return an error except for namespace "local".

tailableCursor

Source

const static OpQueryFlags tailableCursor := OpQueryFlags.<ctor>(2, "TailableCursor")

Tailable means cursor is not closed when the last data is retrieved.
