OPERATOR STATE CHECKPOINTS |
摘要 |
A checkpoint marker can be received at a first operator. The first operator can process the checkpoint marker by sending the checkpoint marker to a second operator and sending state checkpoint information representing a state of the first operator to a checkpoint writer. The checkpoint information can be used to rehydrate the state of one or more operators. For example, after a system failure, system shutdown, etc., checkpoint information can be received from a reader unit at a checkpoint information input queue of the first operator. A state of the first operator can be rehydrated using the checkpoint information. Processing of information in a data input queue of the first operator can be suspended while the checkpoint information is used to rehydrate the state of the first operator. Other operators in a system with the first operator (e.g., the second operator) may be checkpointed and rehydrated in the same manner as the first operator. |
