A schema is a namespace within a catalog that contains tables.

Fields

name: String

Name of schema, relative to parent catalog.

Field 1: name

catalog_name: String

Name of parent catalog.

Field 2: catalog_name

full_name: String

Full name of schema, in form of catalog_name.schema_name.

Field 3: full_name

comment: Option<String>

User-provided free-form text description.

Field 4: comment

properties: HashMap<String, String>

A map of key-value properties attached to the securable.

Field 5: properties

owner: Option<String>

Username of current owner of schema.

Field 6: owner

created_at: Option<i64>

Time at which this schema was created, in epoch milliseconds.

Field 7: created_at

created_by: Option<String>

Username of schema creator.

Field 8: created_by

updated_at: Option<i64>

Time at which this schema was last updated, in epoch milliseconds.

Field 9: updated_at

updated_by: Option<String>

Username of user who last modified schema.

Field 10: updated_by

schema_id: Option<String>

Unique identifier for the schema.

Field 11: schema_id

storage_root: Option<String>

Storage root URL for managed storage location of the schema.

Can be set when creating a schema. When set, managed tables/volumes created in this schema are rooted here; otherwise the parent catalog’s storage location is used. Example: s3://bucket/ucroot.

Field 12: storage_root

storage_location: Option<String>

Storage location URL (full path) for managed storage of the schema.

A unique path under storage_root. Absent when the schema has no storage_root, in which case managed securables fall back to the parent catalog’s storage location. Example: s3://bucket/ucroot/__unitystorage/schemas/{schema_id}.

Field 13: storage_location
