HBase model features

Feature	Description
Basic features	Compatible with most features of HBase 0.94 and 1.1.13 via interface implementation Supports common interfaces, such as put, get, exists, delete, append, increment, scan, and more Supports HBase row locks put, delete, get, and scan interfaces support multiple column families Supports subpartitions starting from V4.3.5 BP2 Supports both standard table models and time series table models starting from V4.3.5 BP2
Filter	Supports filters including CompareFilter, SingleColumnValueFilter, PageFilter, ColumnCountGetFilter, PrefixFilter, SkipFilter, WhileMatchFilter, PageFilter, ColumnPrefixFilter, ColumnPaginationFilter, FirstKeyOnlyFilter, KeyOnlyFilter, RandomRowFilter, and TimestampsFilter Supports multiple filters using FilterList
TTL	Table-level TTL (the TTL policy is set on the table, and all rows expire according to the table-level policy) Supports real-time invisibility of expired data Notice The expired data deletion (TTL) feature is only available for OceanBase KV scenarios. It is disabled for SQL scenarios to prevent unexpected data loss.
MaxVersion	Supports configuring the maximum number of versions to keep, with excess versions deleted asynchronously in the background when combined with TTL
Ecosystem	Supports Flink integration with OBKV-HBase
Development tools	Does not support HBase shell Supports accessing HBase table data via MySQL client

Advanced features

Feature	Description
Transactions	Single operations support row-level transactions Batch operations support single-node transactions Distributed transactions across nodes are not supported yet
Disaster recovery	Leverages all existing disaster recovery capabilities of OceanBase Database, such as multi-replica architecture, primary/standby databases, two-city three-center, three IDCs across two regions, and five IDCs across three regions deployments
Multi-tenancy	Leverages OceanBase Database's multi-tenancy capabilities
Scalability	Leverages OceanBase Database's data partitioning and elastic scaling capabilities
Backup and restore	Leverages OceanBase Database's backup and restore capabilities
Data compression	Supports storage data compression
Data encryption	Supports transparent data encryption (TDE)
