Web18. máj 2024 · Apache Spark maintains state across the execution and binary objects on checkpoints. Therefore you cannot modify the checkpoint directory. As an alternative, copy and update the offset with the input records and store this in a file or a database. Read it during the initialization of the next restart and use the same value in readStream. WebStructured Streaming uses synchronous checkpointing by default. Every micro-batch ensures that all the state updates in that batch are backed up in cloud storage (called “checkpoint location”) before starting the next batch. If a stateful streaming query fails, all micro-batches except the last micro-batch are checkpointed.
