Pola Sairam created HBASE-29588:
-----------------------------------

             Summary: 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
             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.
