DynamoDB restricts the maximum size of an individual project to 400 KB. However, Table Store has no size restrictions for individual rows. Note that no more than 4 MB of data can be submitted at once. For more information, seeLimits in DynamoDBandLimits in Table Store. If you perform ful...
If you store sensitive or confidential data in Amazon DynamoDB, you might want to encrypt that data as close as possible to its origin so your data is protected throughout its lifecycle. You can use the DynamoDB Encryption Client to protect your table data before you send it to DynamoDB...
In this blog post, we show you how theAWS Database Encryption SDK (DB-ESDK)– an upgrade to the DynamoDB Encryption Client – provides client-side encryption to protect sensitive data in transit and at rest. At its core, the DB-ESDK is...
This makes is easier to work with evolving data models and data that varies in shape.DynamoDB supports a number of data types: String, Number, Binary, Boolean, Null, List, Map (similar to a Ruby Hash or JSON object), String Set, Number Set, Binary Set. These data types are encoded ...
DAX maintains anitem cacheto store the results fromGetItemandBatchGetItemoperations. The items in the cache represent eventually consistent data from DynamoDB, and are stored by their primary key values. When an application sends aGetItemorBatchGetItemrequest, DAX tries to read the items directly fr...
Use the connection_string to create the mongoclient and get the MongoDB database connection. Change the username, password, and cluster name. In this python mongodb tutorial, we will create a shopping list and add a few items. For this, we created a database user_shopping_list. MongoDB...
DynamoDB, on the other hand, uses a shift-left model of scalability. It forces you to think about designing your data model up front in a way that will scale. With DynamoDB, there's no black box as to how your database will scale: ...
When you create a DynamoDB global table, it consists of multiple replica tables (one per Region) that DynamoDB treats as a single unit. Every replica has the same table name and the same primary key schema. When an application writes data to a replica table in one Region, DynamoDB propa...
Lambda increments this metric each time a payload can’t be written to the DLQ destination. IteratorAge. If you have Lambda functions that process incoming records from either Kinesis or DynamoDB streams, you want to know as soon as possible when records are not processed as quickly as they ...
To optimize throughput costs and enhance performance, we prioritized reducing the size of items stored in DynamoDB as the DynamoDB pricing model charges for writes in 1KB increments and reads in 4KB increments. Using a numeric datatype instead of string timestamp...
