Settings to avoid data loss

An overview of default configuration properties to avoid data loss.

If for some reason the producer cannot deliver messages that have been consumed and committed by the consumer, it is possible for a MirrorMaker process to lose data. The following collection of properties are set by default and help with preventing data loss when replicating data. In addition, note that MirrorMaker starts correctly if you enter the numeric values in the configuration snippet (rather than using "max integer" for retries and "max long" for max.block.ms).

Producer settings

• acks=all
• retries=2147483647
• max.block.ms=9223372036854775807

Consumer setting

• auto.commit.enable=false

MirrorMaker setting

• abort.on.send.failure=true
