Daniel Roudnitsky commented on HBASE-29588:
-------------------------------------------
Hi [~sairampola6] , could you elaborate on what multi tenant usecase you are
trying to cater to here ? Multiple tenants sharing the same namespace:table
where they cannot see each others data or impact one another within the same
table?
I would also suggest to engage the user/dev list for this proposal.
> New HFile Design For MultiTenant Support
> ----------------------------------------
>
> Key: HBASE-29588
> URL: https://issues.apache.org/jira/browse/HBASE-29588
> Project: HBase
> Issue Type: New Feature
> Components: HFile
> Reporter: Pola Sairam
> Assignee: Pola Sairam
> Priority: Major
> Fix For: 4.0.0-alpha-1
>
>
> HFile is the storage format used by HBase for persisting KeyValue pairs.
> Prior versions (V2, V3) were designed with single-tenant deployments in mind.
> As multi-tenant HBase deployments become more common, there's a need for a
> file format that maintains tenant isolation while preserving storage
> efficiency.
>
> HFile Version 4 addresses this need by enabling multiple tenant-specific
> sections within a single physical file, where each section maintains its own
> metadata and indices. This approach combines the efficiency of shared storage
> with the security of tenant isolation.
