FLINK STATE

Features​

Why is flink involved in managing state

  • Local:
    • Flink state is kept local to the machine that processes it
    • Can be accessed at memory speed
  • Durable: Flink state is fault-tolerant
    • Automatically checkpointed at regular intervals
    • Restored upon failure
  • Vertically scalable
    • Flink state can be kept in embedded RocksDB instances
    • Scale by adding more local disk
  • Horizontally scalable
    • Flink state is redistributed as your cluster grows and shrinks
