> snapshot performance issues
> ---------------------------
>
> Key: AURORA-722
> URL: https://issues.apache.org/jira/browse/AURORA-722
> Project: Aurora
> Issue Type: Bug
> Components: Scheduler
> Reporter: Kevin Sweeney
> Assignee: Kevin Sweeney
> Fix For: 0.6.0
>
>
> In one of our larger production clusters we're seeing issues with snapshot
> performance that cause the scheduler to failover before completing a snapshot.
> For background, the scheduler writes a compressed (when -deflate_snapshots is
> enabled), binary-encoded Snapshot (from api.thrift) to the mesos replicated
> log every hour (or -dlog_snapshot_interval). This snapshot represents most of
> the scheduler's heap usage, including the configuration for all tasks running
> in the cluster.
> Add appropriate instrumentation to the snapshot routine and patch any obvious
> performance bottlenecks.
