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.
