Downstream Change Summary
When the feature flag 'featureFlagTimeseriesMetricIndexes' is enabled, users can create ascending and descending indexes on time-series measurement fields.
Description of Linked Ticket
For ascending indexes, a createIndexes command on a time-series collection measurement field:
{
createIndexes: “abc”,
indexes: [ { key: { a : 1 } } ]
}
will be equivalent to the following operation on the underlying buckets collection:
{
createIndexes: “system.buckets.abc”,
indexes: [ { key: { control.max.a : 1, control.min.a : 1 } } ]
}
For descending indexes, a createIndexes command on a time-series collection measurement field:
{
createIndexes: “abc”,
indexes: [ { key: { a : -1 } } ]
}
will be equivalent to the following operation on the underlying buckets collection:
{
createIndexes: “system.buckets.abc”,
indexes: [ { key: { control.min.a : -1, control.max.a : -1 } } ]
}
