An expression that filters the list of returned backup operations.
A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: <, >, <=, >=, !=, =, or :. Colon : is the contains operator. Filter rules are not case sensitive.
The following fields in the operation are eligible for filtering:
name - The name of the long-running operation
done - False if the operation is in progress, else true.
metadata.@type - the type of metadata. For example, the type string for CreateBackupMetadata is type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata.
metadata.<field_name> - any field in metadata.value. metadata.@type must be specified first if filtering on metadata fields.
error - Error associated with the long-running operation.
response.@type - the type of response.
response.<field_name> - any field in response.value.
You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic, but you can specify AND, OR, and NOT logic explicitly.
Here are a few examples:
done:true - The operation is complete.
(metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata) AND \ metadata.database:prod - Returns operations where:
The operation's metadata type is CreateBackupMetadata.
The source database name of backup contains the string "prod".
(metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata) AND \ (metadata.name:howl) AND \ (metadata.progress.start_time < \"2018-03-28T14:50:00Z\") AND \ (error:*) - Returns operations where:
The operation's metadata type is CreateBackupMetadata.
The backup name contains the string "howl".
The operation started before 2018-03-28T14:50:00Z.
The operation resulted in an error.
(metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CopyBackupMetadata) AND \ (metadata.source_backup:test) AND \ (metadata.progress.start_time < \"2022-01-18T14:50:00Z\") AND \ (error:*) - Returns operations where:
The operation's metadata type is CopyBackupMetadata.
The source backup name contains the string "test".
The operation started before 2022-01-18T14:50:00Z.
The operation resulted in an error.
((metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata) AND \ (metadata.database:test_db)) OR \ ((metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CopyBackupMetadata) AND \ (metadata.source_backup:test_bkp)) AND \ (error:*) - Returns operations where:
The operation's metadata matches either of criteria:
The operation's metadata type is CreateBackupMetadata AND the source database name of the backup contains the string "test_db"
The operation's metadata type is CopyBackupMetadata AND the source backup name contains the string "test_bkp"
