Aerospike support automatic Eviction of expired records: [http://www.aerospike.com/docs/operations/manage/storage/](http://www.aerospike.com/docs/operations/manage/storage/)

Expect to support Trigger UDF during Eviction of expired records, so we can do what we want in the UDF, like:

- Archive the evicted records into backup files.
- Move the evicted records into another table.
- Apply data processing before Archive/Move.

More generically to trigger UDF when a record is changed (Create / Update / Delete).
