# Semantic Conventions for HBase **Status**: [Experimental][DocumentStatus] The Semantic Conventions for [HBase](https://hbase.apache.org/) extend and override the [Database Semantic Conventions](database-spans.md) that describe common database operations attributes in addition to the Semantic Conventions described on this page. `db.system` MUST be set to `"hbase"`. ## Attributes | Attribute | Type | Description | Examples | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Stability | |---|---|---|---|---|---| | [`db.collection.name`](/docs/attributes-registry/db.md) | string | The HBase table name. [1] | `mytable`; `ns:table` | `Conditionally Required` If applicable. |  | | [`db.namespace`](/docs/attributes-registry/db.md) | string | The HBase namespace. [2] | `mynamespace` | `Conditionally Required` If applicable. |  | **[1]:** If table name includes the namespace, the `db.collection.name` SHOULD be set to the full table name. **[2]:** When performing table-related operations, the instrumentations SHOULD extract the namespace from the table name according to the [HBase table naming conventions](https://hbase.apache.org/book.html#namespace_creation). If namespace is not provided, instrumentation SHOULD set `db.namespace` value to `default`.
