> Key: HBASE-22749
> URL: https://issues.apache.org/jira/browse/HBASE-22749
> Project: HBase
> Issue Type: New Feature
> Components: mob
> Reporter: Vladimir Rodionov
> Assignee: Vladimir Rodionov
> Priority: Major
> Attachments: HBASE-22749-branch-2.2-v4.patch, HBASE-22749-master-v1.patch, HBASE-22749-master-v2.patch, HBASE-22749-master-v3.patch, HBASE-22749-master-v4.patch, HBase-MOB-2.0-v3.0.pdf
>
>
> There are several drawbacks in the original MOB 1.0 (Moderate Object Storage) implementation, which can limit the adoption of the MOB feature:
> # MOB compactions are executed in a Master as a chore, which limits scalability because all I/O goes through a single HBase Master server.
> # Yarn/Mapreduce framework is required to run MOB compactions in a scalable way, but this won’t work in a stand-alone HBase cluster.
> # Two separate compactors for MOB and for regular store files and their interactions can result in a data loss (see HBASE-22075)
> The design goals for MOB 2.0 were to provide 100% MOB 1.0 - compatible implementation, which is free of the above drawbacks and can be used as a drop in replacement in existing MOB deployments. So, these are design goals of a MOB 2.0:
> # Make MOB compactions scalable without relying on Yarn/Mapreduce framework
> # Provide unified compactor for both MOB and regular store files
> # Make it more robust especially w.r.t. to data losses.
> # Simplify and reduce the overall MOB code.
> # Provide 100% compatible implementation with MOB 1.0.
> # No migration of data should be required between MOB 1.0 and MOB 2.0 - just software upgrade.
