Object TTL

[Konstantin74R]

Hi,
How to use leveled instead leveldb in Riak 3.0.16 and higher with object TTL for metadata in multibackend?

The leveled TTL support is not yet integrated into Riak, and probably will not be, due to issues with integration with AAE (auto-expiring objects causes significant problems with managing AAE caches).

The long-term intention had been to expire objects through a bucket TTL property instead, with garbage collection of expired objects to be managed through scheduled aae_folds (using the riak_kv_eraser). However, the feature lacks a sponsor at present - so is not being treated as a priority.

It should be noted, that the intention has been to deprecate and retire multi-backend, due to the lack of testing possible for Riak in this configuration mode. However, there is no active work plan to do this at present.
