--------------------------------------------------
Summary: Ability to override TTL on different data-centers, plus
one-way replication
Key: CASSANDRA-8453
URL: https://issues.apache.org/jira/browse/CASSANDRA-8453
Project: Cassandra
Issue Type: Wish
Components: Core
Reporter: Jacques-Henri Berthemet
Here is my scenario:
I want to have one datacenter specialized for operations "DCO" and another for
historical/audit "DCH". Replication will be used between DCO and DCH.
When TTL expires on DCO and data is deleted I'd like the data on DCH to be kept
for other purposes. Ideally a different TTL could be set in DCH.
I guess this also implies that replication should be done only in DCO => DCH
direction so that data is not re-created. But that's secondary, DCH data is not
meant to be modified.
Is this kind of feature feasible for future versions of Cassandra? If not,
would you have some pointers to modify Cassandra in order to achieve this
functionality?
Thank you.
