This manual way of loading could pose problems in case the target table already has data in it. Amazon Redshift Vs DynamoDB – Data replicationĭata loading to Redshift is done by first copying the data to S3 and then using the COPY command to load it into tables. An item size includes both the attribute name size and attribute value size since the DynamoDB is based on a key-value structure. But there is a limit of 400 KB for each item in the table. Redshift has its storage capacity limit at 2 PB size when the ds2.8x large storage type instance is used.įor DynamoDb, Amazon does not officially provide any limit for the maximum table size. Amazon Redshift Vs DynamoDB – Storage capacity Redshift also has a concurrency scaling feature, which if enabled can automatically scale the resources as per the need up to a maximum cluster size limit specified by the user. ![]() Redshift’s elastic resize feature can accomplish this in a matter of minutes. Autoscaling works in this mode as well but within the minimum and maximum range specified by the administrator.įor Redshift, scaling can be done by either upgrading the nodes, adding more nodes or both. Provisioned capacity mode where the customers can specify a specific capacity request rate according to their utilization.In on-demand mode, Scaling happens seamlessly with DynamoDb automatically ramping resources up and down. On-demand mode where the pricing will be based on the actual read and write requests.Thank you for Subscribing to our Newsletter! Amazon Redshift Vs DynamoDB – ScalingĭynamoDb offers two modes of operation for its customers. Scaling can also be accomplished by upgrading the existing nodes. Elastic resize can help the customers to scale their cluster in a matter of minutes by adding more nodes. Similar to DynamoDB, Redshift also can scale at will and offers a feature called elastic resize in its newer generation nodes. A detailed note on Redshift architecture can be found here. The leader node handles all query optimization, client communication, execution plan creation and task assignment to individual nodes. Redshift architecture involves a cluster of nodes with one of them being designated as a leader node. You can read more about Redshift pricing here. Redshift allows its customers to choose from instances optimized for performance and storage and offers a pricing strategy combining both storage and compute resources. Redshift has a PostgreSQL compatible querying layer that can handle very complex queries to return lightning-fast results even in case of scans spanning over millions of rows. A data warehouse is different from a database in the sense that it is more optimized for analytical queries rather than transactional queries. Amazon Redshift FeaturesĪmazon Redshift is a data warehouse offered as a service. This can be used as a trigger for any related data processing. DynamoDB also offers a unique capability called streams which provides an ordered log of change events in a table. When a request comes, the capacity of only the node with that particular primary key range gets utilized which makes it very suitable for workloads distributed uniformly across primary keys. This coupled with the pricing strategy based on the number of requests and occupied storage makes it a very economical option for NoSQL use cases.Īrchitecturally, DynamoDB is organized into nodes and slices of data with each node handling a range of primary keys. It has the capacity to autoscale by dynamically changing the provisioned capacity without affecting the query loads. A non-key attribute that is present in one document could be absent in the next document and the database will not complain which means DynamoDB can very well accommodate semi-structured data as well.Īmazon provides a proprietary query language that can retrieve rows based on the primary key and other key-value pairs in the data. As with all NoSQL databases, the table structure does not mandate any particular structure for data. Every record in a DynamoDB database can be considered as a map of attributes and values with a primary key to retrieve the record. Amazon Redshift Vs DynamoDB – Features AWS DynamoDB FeaturesĭynamoDB is a key-value and document database. Now that we have established the only common attribute between these two services is the ‘database’ part, let’s go into more details on the difference between Redshift and DynamoDB. DynamoDB is a NoSQL database offered as a service with a proprietary query language.
