If you issue a DescribeTable request immediately after a CreateTable request, DynamoDB might return a ResourceNotFoundException. This is because DescribeTable uses an eventually consistent query, and the metadata for your table might not be available at that moment. Wait for a few seconds, and then try the DescribeTable request again.

Examples
This example shows how to get a description for an existing table.
DescribeTable sample
// Create a client
AmazonDynamoDBClient client = new AmazonDynamoDBClient();
// Create DescribeTable request
DescribeTableRequest request = new DescribeTableRequest
{
TableName = "SampleTable"
};
// Issue DescribeTable request and retrieve the table description
TableDescription tableDescription = client.DescribeTable(request).Table;
// View new table properties
Console.WriteLine("Table name: {0}", tableDescription.TableName);
Console.WriteLine("Creation time: {0}", tableDescription.CreationDateTime);
Console.WriteLine("Item count: {0}", tableDescription.ItemCount);
Console.WriteLine("Table size (bytes): {0}", tableDescription.TableSizeBytes);
Console.WriteLine("Table status: {0}", tableDescription.TableStatus);
// List table key schema
List<KeySchemaElement> tableSchema = tableDescription.KeySchema;
for (int i = 0; i < tableSchema.Count; i++)
{
KeySchemaElement element = tableSchema[i];
Console.WriteLine("Key: Name = {0}, KeyType = {1}",
element.AttributeName, element.KeyType);
}
// List attribute definitions
List<AttributeDefinition> attributeDefinitions = tableDescription.AttributeDefinitions;
for (int i = 0; i < attributeDefinitions.Count; i++)
{
AttributeDefinition definition = attributeDefinitions[i];
Console.WriteLine("Attribute: Name = {0}, Type = {1}",
definition.AttributeName, definition.AttributeType);
}
Console.WriteLine("Throughput: Reads = {0}, Writes = {1}",
tableDescription.ProvisionedThroughput.ReadCapacityUnits,
tableDescription.ProvisionedThroughput.WriteCapacityUnits);
