Abstract Value Members

  1. abstract def preload(versions: Iterable[Long], partitionIds: Iterable[String]): Unit

    Downloads the data for the requested versions of the given partitionIds and puts it into the cache for later retrieval.

    Downloads the data for the requested versions of the given partitionIds and puts it into the cache for later retrieval.

    If the data does not fit into the cache completely, this might evict entries from the cache.

  2. abstract def preloadAsync(versions: Iterable[Long], partitionIds: Iterable[String])(implicit ec: ExecutionContext): Future[Unit]

    Downloads the data for the requested versions of the given partitionIds and puts it into the cache for later retrieval.

    Downloads the data for the requested versions of the given partitionIds and puts it into the cache for later retrieval.

    If the data does not fit into the cache completely, this might evict entries from the cache.

    Please note that using a work stealing thread pool might lead to starvation.

  3. abstract def read(version: Long, partitionId: String): Option[T]

    Get data from a versioned layer with a given version and partition id (String).

    Get data from a versioned layer with a given version and partition id (String).

    version

    Catalog version against which to run the query.

    partitionId

    Partition id.

    returns

    an Option with the data retrieved (None if no data is retrieved).
