Abstract: Techniques are disclosed for migrating data objects stored by the source DDOS from the source DDOS to the target DDOS while at least the source DDOS is live and available to process requests for access to the data objects being migrated. The techniques also provide eventual consistency between data objects that are created, updated, or deleted in the source DDOS that are applicable to the migration and that occur while the migration is being performed.

Abstract: A non-transitory computer-readable storage media storing program instructions which, when executed by one or more processors, cause the one or more processors to perform: receiving a query to the distributed file system; determining a particular partition, associated with the data warehouse system, targeted by the query; accessing a repository associated with the data warehouse system to determine whether a partition-to-cluster mapping entry for the particular partition targeted by the query exists in the repository; in response to a determination that the entry for the particular partition exists in the repository, obtaining, from the entry for the particular partition, an identifier of a particular cluster to which the particular partition is assigned by the entry for the particular partition, the particular cluster being one of a plurality of clusters of the distributed file system, each cluster of the plurality of clusters having one name node and a plurality of data nodes.

Abstract: Techniques are disclosed for converting the data of data objects stored in a DDOS from one data format to another while the system is live and available to process requests for access to the data objects being converted. The conversion techniques do not require taking the DDOS offline. The conversion techniques also do not require locking a data object for the entire conversion of the data object.

Abstract: A system converts the data of data objects stored in a DDOS from one data format to another while the system is live and available to process requests for access to the data objects being converted. This process does not require taking the DDOS offline and also does not require locking a data object for the entire conversion of the data object.
