Spark WAL

Spark Streaming includes the option of using Write Ahead Logs or WAL to protect against failures.  A Write Ahead Logs (WAL) is like a journal log. A WAL structure enforces fault-tolerance by saving all data received by the receivers to logs file located in checkpoint directory. 

WAL is enabled through spark.streaming.receiver.writeAheadLog.enable property.
