What is

Amazon Redshift Exceeded Storage Limit

 ?

Understanding Amazon Redshift

Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud. It allows you to analyze your data using your existing business intelligence tools, making it a popular choice for organizations looking to handle large-scale data analytics efficiently.

Identifying the Symptom: Exceeded Storage Limit

When using Amazon Redshift, you might encounter an error indicating that the storage limit has been exceeded. This typically manifests as a failure to load new data or execute queries that require additional storage space.

Common Error Messages

Some common error messages associated with this issue include:

  • "Exceeded storage limit"
  • "Disk full"
  • "Cannot allocate memory"

Delving into the Issue

The "Exceeded Storage Limit" error occurs when your Amazon Redshift cluster has reached its maximum storage capacity. This can happen if the data volume grows beyond the allocated storage or if there is inefficient use of storage resources.

Understanding Storage Allocation

Amazon Redshift uses a distributed architecture, where data is stored across multiple nodes. Each node has a specific amount of storage, and the total storage capacity is the sum of all nodes' storage. When this capacity is reached, the cluster cannot store additional data.

Steps to Resolve the Exceeded Storage Limit Issue

To resolve this issue, you can either delete unnecessary data or increase the cluster size. Here are detailed steps for both approaches:

Option 1: Deleting Unnecessary Data

  1. Identify large tables or unused data using the following query: SELECT "table", size FROM svv_table_info ORDER BY size DESC;
  2. Delete or archive old data that is no longer needed. For example: DELETE FROM your_table WHERE condition;
  3. Vacuum the tables to reclaim storage space: VACUUM your_table;

Option 2: Increasing Cluster Size

  1. Consider adding more nodes to your cluster. This can be done via the AWS Management Console or AWS CLI. For example, using AWS CLI: aws redshift modify-cluster --cluster-identifier your-cluster-id --number-of-nodes new-node-count
  2. Monitor the cluster's performance and storage usage to ensure it meets your needs.
