Propel's Serverless ClickHouse offers a solution for transforming DynamoDB JSON data into a more analytics-friendly format by using its forever-free plan with pay-per-query pricing and instant auto-scaling. The process involves transferring DynamoDB events to ClickHouse and flattening the JSON structure into a tabular format through the creation of Materialized Views. This transformation extracts specific fields from the JSON, casts them into appropriate data types, and flattens them for easier querying. The setup accommodates both multi-table and single-table designs, allowing users to create separate Data Pools for each table or entity. This approach enhances data accessibility and analytics capabilities, enabling efficient querying and management of event-driven data architectures.
