Abstract: Embodiments are directed to simultaneously backing up data from multiple locations to a single location and to restoring data from a single location to multiple locations simultaneously. In an embodiment, a computer system receives a backup command from a user which indicates that various specified portions of data are to be backed up. The data portions are stored in multiple different locations in a parallel database. The computer system generates multiple backup commands specific for each location in which the data is stored. The backup commands initiate a parallel backup from the various locations to a single location in a data store. The computer system also executes the generated backup commands in parallel, so that the data from each of the different locations is backed up in the data store.

Abstract: Embodiments are directed to establishing a fault tolerant parallel database system and to detecting the health of parallel database services. In an embodiment, a computer system establishes a control node cluster that includes at least one active control node and at least one spare control node. Each node of the control node cluster includes specific functions assumable only by other control nodes. The computer system also establishes a compute node cluster that includes at least one active computing node, at least one spare computing node, at least one active storage node and at least one spare storage node. Each of the computing and storage nodes includes specific functions assumable only by other computing and storage nodes. The computer system detects a failure of an active node and instantiates a corresponding spare node that is configured to perform the functions of the failed active node.

Abstract: A producer node receives data that is to be transmitted to a consumer node. The producer node receives a credit indication from the consumer node indicating that a portion of credit has been extended to the producer node. The credit portion specifies the amount of data that is to be sent to the consumer node. The producer node sends the amount of data specified in the credit indication to the consumer node. The consumer node receives data that is to be processed. The consumer node returns the portion of credit indicated in the credit indication to a credit pool, where, upon addition to the credit pool, the credit is made available for distribution to the producer node. The consumer node sends a new credit indication to the producer node indicating a specified amount of data that is to be sent to the consumer node to be processed.
