NAME

Paws::DynamoDB::TableDescription

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::DynamoDB::TableDescription object:

$service_obj->Method(Att1 => { AttributeDefinitions => $value, ..., TableStatus => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::DynamoDB::TableDescription object:

$result = $service_obj->Method(...);
$result->Att1->AttributeDefinitions

DESCRIPTION

Represents the properties of a table.

ATTRIBUTES

AttributeDefinitions => ArrayRef[Paws::DynamoDB::AttributeDefinition]

An array of I<AttributeDefinition> objects. Each of these objects
describes one attribute in the table and index key schema.

Each AttributeDefinition object in this array is composed of:

  • AttributeName - The name of the attribute.

  • AttributeType - The data type for the attribute.

CreationDateTime => Str

The date and time when the table was created, in UNIX epoch time
format.

GlobalSecondaryIndexes => ArrayRef[Paws::DynamoDB::GlobalSecondaryIndexDescription]

The global secondary indexes, if any, on the table. Each index is
scoped to a given hash key value. Each element is composed of:

  • Backfilling - If true, then the index is currently in the backfilling phase. Backfilling occurs only when a new global secondary index is added to the table; it is the process by which DynamoDB populates the new index with data from the table. (This attribute does not appear for indexes that were created during a CreateTable operation.)

  • IndexName - The name of the global secondary index.

  • IndexSizeBytes - The total size of the global secondary index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

  • IndexStatus - The current status of the global secondary index:

    • CREATING - The index is being created.

    • UPDATING - The index is being updated.

    • DELETING - The index is being deleted.

    • ACTIVE - The index is ready for use.

  • ItemCount - The number of items in the global secondary index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

  • KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same hash key attribute as the table.

  • Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:

    • ProjectionType - One of the following:

      • KEYS_ONLY - Only the index and primary keys are projected into the index.

      • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes are in NonKeyAttributes.

      • ALL - All of the table attributes are projected into the index.

    • NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes, summed across all of the secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

  • ProvisionedThroughput - The provisioned throughput settings for the global secondary index, consisting of read and write capacity units, along with data about increases and decreases.

If the table is in the DELETING state, no information about indexes will be returned.

ItemCount => Int

The number of items in the specified table. DynamoDB updates this value
approximately every six hours. Recent changes might not be reflected in
this value.

KeySchema => ArrayRef[Paws::DynamoDB::KeySchemaElement]

The primary key structure for the table. Each I<KeySchemaElement>
consists of:

  • AttributeName - The name of the attribute.

  • KeyType - The key type for the attribute. Can be either HASH or RANGE.

For more information about primary keys, see Primary Key in the Amazon DynamoDB Developer Guide.

LatestStreamArn => Str

The Amazon Resource Name (ARN) that uniquely identifies the latest
stream for this table.

LatestStreamLabel => Str

A timestamp, in ISO 8601 format, for this stream.

Note that LatestStreamLabel is not a unique identifier for the stream, because it is possible that a stream from another table might have the same timestamp. However, the combination of the following three elements is guaranteed to be unique:

  • the AWS customer ID.

  • the table name.

  • the StreamLabel.

LocalSecondaryIndexes => ArrayRef[Paws::DynamoDB::LocalSecondaryIndexDescription]

Represents one or more local secondary indexes on the table. Each index
is scoped to a given hash key value. Tables with one or more local
secondary indexes are subject to an item collection size limit, where
the amount of data within a given item collection cannot exceed 10 GB.
Each element is composed of:

  • IndexName - The name of the local secondary index.

  • KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same hash key attribute as the table.

  • Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:

    • ProjectionType - One of the following:

      • KEYS_ONLY - Only the index and primary keys are projected into the index.

      • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes are in NonKeyAttributes.

      • ALL - All of the table attributes are projected into the index.

    • NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes, summed across all of the secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

  • IndexSizeBytes - Represents the total size of the index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

  • ItemCount - Represents the number of items in the index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

If the table is in the DELETING state, no information about indexes will be returned.

ProvisionedThroughput => Paws::DynamoDB::ProvisionedThroughputDescription

The provisioned throughput settings for the table, consisting of read
and write capacity units, along with data about increases and
decreases.

StreamSpecification => Paws::DynamoDB::StreamSpecification

The current DynamoDB Streams configuration for the table.

TableArn => Str

The Amazon Resource Name (ARN) that uniquely identifies the table.

TableName => Str

The name of the table.

TableSizeBytes => Int

The total size of the specified table, in bytes. DynamoDB updates this
value approximately every six hours. Recent changes might not be
reflected in this value.

TableStatus => Str

The current state of the table:

  • CREATING - The table is being created.

  • UPDATING - The table is being updated.

  • DELETING - The table is being deleted.

  • ACTIVE - The table is ready for use.
