the class StorageUnitDaoImpl method getStorageUnitsByPartitionFiltersAndStorages.

/**
 * Retrieves a list of storage unit entities per specified parameters. This method processes a sublist of partition filters specified by
 * partitionFilterSubListFromIndex and partitionFilterSubListSize parameters.
 *
 * @param businessObjectFormatKey the business object format key (case-insensitive). If a business object format version isn't specified, the latest
 * available format version for each partition value will be used
 * @param partitionFilters the list of partition filter to be used to select business object data instances. Each partition filter contains a list of
 * primary and sub-partition values in the right order up to the maximum partition levels allowed by business object data registration - with partition
 * values for the relative partitions not to be used for selection passed as nulls
 * @param businessObjectDataVersion the business object data version. If a business object data version isn't specified, the latest data version based on
 * the specified business object data status is returned
 * @param businessObjectDataStatus the business object data status. This parameter is ignored when the business object data version is specified. When
 * business object data version and business object data status both are not specified, the latest data version for each set of partition values will be
 * used regardless of the status
 * @param storageNames the list of storage names where the business object data storage units should be looked for (case-insensitive)
 * @param storagePlatformType the optional storage platform type, e.g. S3 for Hive DDL. It is ignored when the list of storages is not empty
 * @param excludedStoragePlatformType the optional storage platform type to be excluded from search. It is ignored when the list of storages is not empty or
 * the storage platform type is specified
 * @param partitionFilterSubListFromIndex the index of the first element in the partition filter sublist
 * @param partitionFilterSubListSize the size of the partition filter sublist
 * @param selectOnlyAvailableStorageUnits specifies if only available storage units will be selected or any storage units regardless of their status
 *
 * @return the list of storage unit entities sorted by partition values
