Abstract Value Members
- abstract def externalLink: T
- abstract def put(batchDataset: BatchDataset): Unit
- abstract def put(dataPoints: Seq[DataPoint]): Unit
- abstract def schema: Schema
- abstract def setLinkedValues(dstaset: BatchDataset, exprs: Set[LinkExpr[_]]): Unit
Sets requested external link expressions values into a batch of ValueData
Sets requested external link expressions values into a batch of ValueData
- exprs
expressions to be set
- abstract def transformCondition(condition: FlatAndCondition, startTime: Time, user: YupanaUser): Seq[ConditionTransformation]
Transforms condition according to filter by this external link conditions.
Transforms condition according to filter by this external link conditions. For example:
linkX_fieldY = 'value1' AND linkY_fieldZ = 'value2' AND time >= TIMESTAMP '2019-02-01' AND time < TIMESTAMP '2019-02-28'
might be transformed by
ExternalLinkServicefor catalogX to:tagX in (`tagValue1`, `tagValue2`) AND linkY_fieldZ = 'value2' AND time >= TIMESTAMP '2019-02-01' AND time < TIMESTAMP '2019-02-28'
So, the main idea is to provide more primitive conditions using values for supported fields (and maybe other fields as a context for catalog).
- condition
condition to be transformed
- startTime
query start time. This might be used to produce nested queries
- user
yupana user performing the query
- returns
sequence of transformations applied to the initial condition, basically each transformation is a mapping from one expression to another. It should preserve time bounds even if there no conditions supported by this catalog.
