def
queryDependencies(version: Version): Seq[Dependency]
Queries the dependencies for a particular catalog version.
Queries the dependencies for a particular catalog version.
- version

def
queryLatestVersion(): BaseVersion
Queries the latest version of the catalog.
Queries the latest version of the catalog.
- returns

def
queryLayerVersions(version: Version): Map[Id, Version]
Queries the latest version for each of the catalog layers.
Queries the latest version for each of the catalog layers. This is the version of the most recent event affecting that layer, either because a partition was changed and/or deleted in that version.
For some layers, this version may be older than the catalog's overall version, particularly if those layers did not change, but other layers have changed.
- version
The version for which the catalog's layers are queried.
- returns
The latest version for each of the catalog's layers.
- Definition Classes
- CatalogLightProxy → CatalogLight
- Note
Layers that have never changed since catalog creation are not returned.
-
def
queryMinimumVersion(): BaseVersion
Queries the minimum version of the catalog.
Queries the minimum version of the catalog.
- returns
The minimum catalog version available in the Data API, or com.here.platform.data.processing.catalog.utils.EmptyCatalog otherwise.

def
queryPartitionChangeHistory(version: Version, layer: Id, partition: Name, direction: Catalog.ChangeHistoryDirection.Value): Seq[Change]
Queries metadata history for the selected partition.
Queries metadata history for the selected partition.
This query is done directly in the Driver, and the metadata is returned. You can query up to 100 changes with one call.
- version
The version from which to begin the change history search.
- layer
The layer that contains the partition.
- partition
The partition to query the change history for.
- direction
Specifies the direction in which to lookup the history: forward or backward.
- returns
A Partition.Change object containing the partition size and checksum.
- Definition Classes
- CatalogLightProxy → CatalogLight
- Note
This method is scheduled to be deprecated in a future release. Only supported by the Datastore1 implementation.

def
querySingleChanges(versionStart: Version, versionEnd: Version, layer: Id, partitions: Set[Name]): Map[Key, Change]
Queries metadata for the selected partitions changed between given versions.
Queries metadata for the selected partitions changed between given versions.
This query is done directly in the Driver, and the metadata is returned. You can query up to 100 partitions with one call.
- versionStart
Query the partitions changed after this version.
- versionEnd
Query the changed partitions up to this version.
- layer
The layer that contains the partitions being queried.
- partitions
The partition names that should be queried.
- returns
The queried metadata, for partitions that have content in the catalog at the specified version. Partitions not present in the catalog at the specified version are not returned.
- Definition Classes
- CatalogLightProxy → CatalogLight
- Note
This method is only intended to be used internally, by the library. When implementing your compiler, you are encouraged to use Catalog.queryAll/Catalog.queryChanges instead, as these methods are implemented in a distributed way.

def
querySinglePartitions(version: Version, layer: Id, partitions: Set[Name]): Map[Key, Meta]
Queries metadata for the selected partitions.
Queries metadata for the selected partitions.
This query is done directly in the Driver, and the metadata is returned. You can query up to 100 partitions with one call.
- version
The version at which the catalog is queried for partitions.
- layer
The layer that contains the partitions being queried.
- partitions
The partition names that should be queried.
- returns
The queried metadata, for partitions that have content in the catalog at the specified version. Partitions not present in the catalog at the specified version are not returned.

def
startCommit(baseVersion: BaseVersion, dependencies: Seq[Dependency]): CommitToken
Starts a new multipart commit on top of an existing version or an empty catalog.
Starts a new multipart commit on top of an existing version or an empty catalog.
- baseVersion
The current version of the catalog in the Data API. This information is required to prevent race conditions if the version is changed elsewhere, in another process, while we are preparing data for the commit. If the catalog is empty, use utils.EmptyCatalog.
- dependencies
The upstream dependencies for this commit.
- returns
A new multipart commit token representing the commit in progress.
