Hey

Was going through one of your [documents](https://www.aerospike.com/docs/architecture/assets/AerospikeACIDSupport.pdf). This says under Handling conflict.

> Auto merge works as follows:

> • TTL (time-to-live) based: The record with the highest TTL wins

> • Generation based: The record with the highest generation wins

> Application merge works as follows:

> • When two versions of the same data item are available in the cluster, a read of this value will return both versions, allowing the application to resolve the inconsistency.

> • The client application – the only entity with knowledge of how to resolve these differences – must then re-write the data in a consistent fashion.

Wanted to know if Application based merge still works ? As Other place the options of handling conflicts are either ttl or generation.

Currently, TTL and generation are still the only 2 options available for handling conflict.

Hi @wchu

Can you please confirm if this is an outdated config now: [http://www.aerospike.com/docs/reference/configuration/#allow-versions](http://www.aerospike.com/docs/reference/configuration/#allow-versions)

In light of your above answer, it looks like this config is no more supported. Kindly confirm and deprecate it in doc if that’s the case. Thanks.
