Response Structure
(dict) --
Table (dict) --
The Table object that defines the specified table.
Name (string) --
The table name. For Hive compatibility, this must be entirely lowercase.
DatabaseName (string) --
The name of the database where the table metadata resides. For Hive compatibility, this must be all lowercase.
Description (string) --
A description of the table.
Owner (string) --
The owner of the table.
CreateTime (datetime) --
The time when the table definition was created in the Data Catalog.
UpdateTime (datetime) --
The last time that the table was updated.
LastAccessTime (datetime) --
The last time that the table was accessed. This is usually taken from HDFS, and might not be reliable.
LastAnalyzedTime (datetime) --
The last time that column statistics were computed for this table.
Retention (integer) --
The retention time for this table.
StorageDescriptor (dict) --
A storage descriptor containing information about the physical storage of this table.
Columns (list) --
A list of the Columns in the table.
(dict) --
A column in a Table .
Name (string) --
The name of the Column .
Type (string) --
The data type of the Column .
Comment (string) --
A free-form text comment.
Parameters (dict) --
These key-value pairs define properties associated with the column.
Location (string) --
The physical location of the table. By default, this takes the form of the warehouse location, followed by the database location in the warehouse, followed by the table name.
AdditionalLocations (list) --
A list of locations that point to the path where a Delta table is located.
InputFormat (string) --
The input format: SequenceFileInputFormat (binary), or TextInputFormat , or a custom format.
OutputFormat (string) --
The output format: SequenceFileOutputFormat (binary), or IgnoreKeyTextOutputFormat , or a custom format.
Compressed (boolean) --
Trueif the data in the table is compressed, orFalseif not.
NumberOfBuckets (integer) --
Must be specified if the table contains any dimension columns.
SerdeInfo (dict) --
The serialization/deserialization (SerDe) information.
Name (string) --
Name of the SerDe.
SerializationLibrary (string) --
Usually the class that implements the SerDe. An example is org.apache.hadoop.hive.serde2.columnar.ColumnarSerDe .
Parameters (dict) --
These key-value pairs define initialization parameters for the SerDe.
BucketColumns (list) --
A list of reducer grouping columns, clustering columns, and bucketing columns in the table.
SortColumns (list) --
A list specifying the sort order of each bucket in the table.
(dict) --
Specifies the sort order of a sorted column.
Column (string) --
The name of the column.
SortOrder (integer) --
Indicates that the column is sorted in ascending order ( == 1 ), or in descending order ( ==0 ).
Parameters (dict) --
The user-supplied properties in key-value form.
SkewedInfo (dict) --
The information about values that appear frequently in a column (skewed values).
SkewedColumnNames (list) --
A list of names of columns that contain skewed values.
SkewedColumnValues (list) --
A list of values that appear so frequently as to be considered skewed.
SkewedColumnValueLocationMaps (dict) --
A mapping of skewed values to the columns that contain them.
StoredAsSubDirectories (boolean) --
Trueif the table data is stored in subdirectories, orFalseif not.
SchemaReference (dict) --
An object that references a schema stored in the Glue Schema Registry.
When creating a table, you can pass an empty list of columns for the schema, and instead use a schema reference.
SchemaId (dict) --
A structure that contains schema identity fields. Either this or the SchemaVersionId has to be provided.
SchemaArn (string) --
The Amazon Resource Name (ARN) of the schema. One of SchemaArn or SchemaName has to be provided.
SchemaName (string) --
The name of the schema. One of SchemaArn or SchemaName has to be provided.
RegistryName (string) --
The name of the schema registry that contains the schema.
SchemaVersionId (string) --
The unique ID assigned to a version of the schema. Either this or the SchemaId has to be provided.
SchemaVersionNumber (integer) --
The version number of the schema.
PartitionKeys (list) --
A list of columns by which the table is partitioned. Only primitive types are supported as partition keys.
When you create a table used by Amazon Athena, and you do not specify any partitionKeys , you must at least set the value of partitionKeys to an empty list. For example:
"PartitionKeys": []
(dict) --
A column in a Table .
Name (string) --
The name of the Column .
Type (string) --
The data type of the Column .
Comment (string) --
A free-form text comment.
Parameters (dict) --
These key-value pairs define properties associated with the column.
ViewOriginalText (string) --
Included for Apache Hive compatibility. Not used in the normal course of Glue operations. If the table is a VIRTUAL_VIEW , certain Athena configuration encoded in base64.
ViewExpandedText (string) --
Included for Apache Hive compatibility. Not used in the normal course of Glue operations.
TableType (string) --
The type of this table. Glue will create tables with the EXTERNAL_TABLE type. Other services, such as Athena, may create tables with additional table types.
Glue related table types:
EXTERNAL_TABLE
Hive compatible attribute - indicates a non-Hive managed table.
GOVERNED
Used by Lake Formation. The Glue Data Catalog understands GOVERNED .
Parameters (dict) --
These key-value pairs define properties associated with the table.
CreatedBy (string) --
The person or entity who created the table.
IsRegisteredWithLakeFormation (boolean) --
Indicates whether the table has been registered with Lake Formation.
TargetTable (dict) --

CatalogId (string) --
The ID of the Data Catalog in which the table resides.
DatabaseName (string) --
The name of the catalog database that contains the target table.
Name (string) --
The name of the target table.
CatalogId (string) --
The ID of the Data Catalog in which the table resides.
VersionId (string) --
The ID of the table version.
