Description
Add support for operation hedging, as in SERVER-45432, with an explicit readPreference.
The form of that readpreference should be:
// some existing command
|
{
|
...,
|
$readPreference: {
|
mode: "nearest", |
hedge: {
|
enabled: true, // default value is true |
}
|
}
|
which should map to RemoteCommandRequestOnAny::HedgeOptions of
- count = 1
- as in implicit readPreference nearest
