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.
