get-tables

Description

Retrieves the definitions of some or all of the tables in a given Database .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

get-tables is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: TableList

Synopsis

  get-tables
[--catalog-id <value>]
--database-name <value>
[--expression <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--catalog-id (string)

The ID of the Data Catalog where the tables reside. If none is provided, the AWS account ID is used by default.

--database-name (string)

The database in the catalog whose tables to list. For Hive compatibility, this name is entirely lowercase.

--expression (string)

A regular expression pattern. If present, only those tables whose names match the pattern are returned.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

TableList -> (list)

A list of the requested Table objects.

(structure)

Represents a collection of related data organized in columns and rows.

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 -> (timestamp)

The time when the table definition was created in the Data Catalog.

UpdateTime -> (timestamp)

The last time that the table was updated.

LastAccessTime -> (timestamp)

The last time that the table was accessed. This is usually taken from HDFS, and might not be reliable.

LastAnalyzedTime -> (timestamp)

The last time that column statistics were computed for this table.

Retention -> (integer)

The retention time for this table.

StorageDescriptor -> (structure)

A storage descriptor containing information about the physical storage of this table.

Columns -> (list)

A list of the Columns in the table.

(structure)

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 -> (map)

These key-value pairs define properties associated with the column.

key -> (string)

value -> (string)

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.

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)

True if the data in the table is compressed, or False if not.

NumberOfBuckets -> (integer)

Must be specified if the table contains any dimension columns.

SerdeInfo -> (structure)

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 -> (map)

These key-value pairs define initialization parameters for the SerDe.

key -> (string)

value -> (string)

BucketColumns -> (list)

A list of reducer grouping columns, clustering columns, and bucketing columns in the table.

(string)

SortColumns -> (list)

A list specifying the sort order of each bucket in the table.

(structure)

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 -> (map)

The user-supplied properties in key-value form.

key -> (string)

value -> (string)

SkewedInfo -> (structure)

The information about values that appear frequently in a column (skewed values).

SkewedColumnNames -> (list)

A list of names of columns that contain skewed values.

(string)

SkewedColumnValues -> (list)

A list of values that appear so frequently as to be considered skewed.

(string)

SkewedColumnValueLocationMaps -> (map)

A mapping of skewed values to the columns that contain them.

key -> (string)

value -> (string)

StoredAsSubDirectories -> (boolean)

True if the table data is stored in subdirectories, or False if not.

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": []
