Can we run local dynamodb
In November 2020, AWS DynamoDB has released a new feature to export the contents of a table to S3 without performance impact, leveraging Point-In-Time-Recovery (PITR). In any case, there was no out-of-the-box feature that could dump a DynamoDB table for export, without having a performance, cost or engineering impact. AWS Data Pipeline), or invest a lot of your own engineering effort to extract the data yourself. Until very recently, getting bulk data out of AWS DynamoDB typically required the use of either specialised vendor or cloud provider tools (e.g.
We will tackle both the sparse data and semi-structured data challenges, using plain old SQL.
CAN WE RUN LOCAL DYNAMODB HOW TO
In this article I will to show you how to successfully integrate DynamoDB data with Snowflake, in a cost-effective and cloud native way. It can be difficult to transform semi-structured data to the relational table format found in data warehouses, or make sense of sparse data patterns commonly used in single table designs. Integrating with Data Warehousesĭespite providing flexibility for transactional data users, NoSQL tables often present challenges for analytics teams. With AWS DynamoDB in particular, much attention has been paid to single table designs in recent years that optimize read and write patterns in order to effectively allow multiple domains of data within a single table. NoSQL databases are often regarded for their schemaless capabilities that - as well as offering flexibility - demand tolerant applications as data structures evolve over time.
One key differentiator, however is cost model - RDS attracts an hourly pricing model for compute, irrespective of actual demand, whilst DynamoDB charges you only for what you use. Both are easily scaled and highly available across multiple availability zones, and even multiple geographical regions. There are a wide range of database options on offer from AWS for different workloads, yet RDS and DynamoDB are by far the most established and with the most mature capabilities to support mainstream and high performance requirements. In fact, in a recent AWS blog post about Prime Day, it is claimed it sustained a peak load of 80 million requests per second! Whilst most customers are unlikely to reach that level of sustained throughput, it demonstrates the extent to which the service is designed to scale. But first… Why DynamoDB is so popularĪWS DynamoDB is a cloud native NoSQL database service, renowned for its performance and stability. In this article we are going to discuss a new way to batch load your DynamoDB tables directly into Snowflake without proprietary tools.
