Java SDK operations
There are eight user-defined private functions that are being invoked in the following code.
We will see each and every function in detail:
public class AwsSdkDemo {
static AmazonDynamoDBClient client;
public static void main(String[] args) {
try {
initializeCredentials();
String tableName = "Tbl_Book";
if (Tables.doesTableExist(client, tableName)) {
System.out.println("Table " + tableName + " already
EXISTS");
}
else {
ArrayList<AttributeDefinition> attributeDefinitions
= getTableAttributes();
ArrayList<KeySchemaElement> keySchemaElements =
getTableKeySchema();
LocalSecondaryIndex localSecondaryIndex =
getLocalSecondaryIndex();
ArrayList<LocalSecondaryIndex> localSecondaryIndexes
= newArrayList<LocalSecondaryIndex>();
localSecondaryIndexes.add(localSecondaryIndex);
GlobalSecondaryIndex globalSecondaryIndex =
getGlobalSecondaryIndex();
ProvisionedThroughput provisionedThroughput =
getProvisionedThroughput();
CreateTableRequest request = new CreateTableRequest()
.withTableName(tableName)
.withAttributeDefinitions(attributeDefinitions)
.withKeySchema(keySchemaElements)
.withProvisionedThroughput(provisionedThroughput)
