- val Collection: String
Option Key: The name of the Columnar collection.
- val ConnectionIdentifier: String
Option Key: Instead of using the "default" connection, allows to connect to a different Columnar cluster.
- val Database: String
Option Key: The name of the Columnar database, which overrides any implicit database configured.
- val Filter: String
Option Key: a Columnar SQL++ expression which acts as an additional filter on every columnar query, including schema inference.
- val InferLimit: String
Option Key: The limit of how many records to load during schema inference.
Option Key: The limit of how many records to load during schema inference.
The default can be found in DefaultConstants.DefaultInferLimit
- val NotBoundedScanConsistency: String
Option Value: Not bounded scan consistency - to be used with ScanConsistency as the key.
Option Value: Not bounded scan consistency - to be used with ScanConsistency as the key.
This is the default and usually does not need to be specified. The query will be executed immediately, and it might not include documents which have just been written and not made it into the index yet.
- val RequestPlusScanConsistency: String
Option Value: Request plus scan consistency - to be used with ScanConsistency as the key.
Option Value: Request plus scan consistency - to be used with ScanConsistency as the key.
If this value is set, the query will wait until it has caught up to the recent mutations, which will make sure that documents which just have been written are part of the result set.
- val ScanConsistency: String
Option Key: Allows to override the scan consistency for the query performed.
- val Scope: String
Option Key: The name of the Columnar scope, which overrides any implicit scope configured.
- val Timeout: String
Option Key: The timeout to use which overrides the default configured.
Option Key: The timeout to use which overrides the default configured.
The value is a string and must be parsable from a scala Duration.
