Jesse Yates commented on HBASE-6180:
------------------------------------
Looking at the documentation from Amazon's hosted HBase solution
(http://docs.amazonwebservices.com/ElasticMapReduce/latest/DeveloperGuide/emr-hbase-backup-restore.html),
they provide the option to do either a --consistent view (with synchronization
across all the nodes) or a globally inconsistent view (but per-node
consistency). I think keeping the "current" full consistency as an option is a
'nice to have', but making the timestamp based backup - fuzzy consistency - the
default.
> [brainstorm] Timestamp based snapshots in HBase 0.96
> ----------------------------------------------------
>
> Key: HBASE-6180
> URL: https://issues.apache.org/jira/browse/HBASE-6180
> Project: HBase
> Issue Type: Brainstorming
> Reporter: Jesse Yates
> Fix For: 0.96.0
>
>
> Discussion ticket around doing timestamp based snapshots in HBase as an
> extension/follow-on work for HBASE-6055. The implementation in HBASE-6055 (as
> originally defined) is not sufficient for real-time clusters because it
> requires downtime to take the snapshot.
> Time-stamp based snapshots should not require downtime at the cost of
> achieving global consistency.
