#LOCAL DYNAMODB CONSOLE HOW TO#

You will also figure out how to add, edit, query, export, and delete table data using the AWS Management Console. You simplyВ select an AWS region, define the needed indexes for each table you will create, and Amazon takes care of everything else.Дuring this lab, you will learn how to create DynamoDB tables, with and without local or global secondary indexes, and how to manage your table data. DynamoDB is designed to provide automated storage scaling and low latency.В It is particularly useful when your application must read and store massive amounts of data and you need speed and reliability (Amazon works with replicas of your database in three different Availability Zones). If( DynamoDBВ is a NoSQL Database in the cloud, suitable for anyone needing a reliable and fully managed NoSQL solution. get cloudconfiguration configAlias maxconnectionsД®mpData = new Employee().get cloudconfiguration configAlias serviceName maxconnections.get cloudconfiguration configAlias serviceName.set cloudconfiguration configAlias maxconnections=40 numRetries=6.set cloudconfiguration configAlias maxconnections=40.add cloudconfiguration serviceName=DYNAMODB alias=configAlias accelerateModeEnabled=true chunkedEncodingEnabled=true dualStackEnabled=true pathStyleAccessEnabled=true checksumValidationEnabled=true maxConnections=50 connectionMaxIdleTime=10s useIdleConnectionReaper=true socketTimeout=10s expectContinueEnabled=true connectionTimeout=10s connectionTimeToLive=10s connectionAcquisitionTimeout=10s useSystemPropertyValues=true numRetries=5 apiCallAttemptTimeout=2s.delete cloudcredentialВ myAliasForCloudCredential.show cloudcredentialВ myAliasForCloudCredential.get cloudcredentialВ myAliasForCloudCredential alias.get cloudcredentialВ myAliasForCloudCredential region.get cloudcredentialВ myAliasForCloudCredential secretAccessKey.get cloudcredentialВ myAliasForCloudCredential accessKeyId.get cloudcredentialВ myAliasForCloudCredential vendorName.set cloudcredentialВ myAliasForCloudCredential region=us-west-2.

A local secondary index is 'local' in the sense that every partition of a local secondary index is scoped to a base table partition that has the same partition key value.

Local secondary index - an index that has the same partition key as the base table, but a different sort key.

A global secondary index is considered 'global' because queries on the index can span all the data in the base table, across all partitions.

Global secondary index - an index with a partition key and a sort key that can be different from those on the base table.

There are two types of secondary indexes in DynamoDB: A table can have multiple secondary indexes, which gives your applications access to many different query patterns. You can retrieve data from the index using a Query, like the way you issue a query in a table. To address this, you can create one or more secondary indexes on a table, and issue Query requests against these indexes.ДЄ secondary index is a data structure that contains a subset of attributes from a table, along with an alternate key to support Query operations. However, many applications might benefit from having one or more secondary (or alternate) keys available, to allow efficient access to data with attributes other than the primary key. Amazon DynamoDB provides faster access to items in a table by specifying primary key values.
