Event payload consistency across Serverless đâď¸ #96
Valentines day, 1MB is the new limit
In the previous issue, DynamoDB with fault injection testing đâď¸ #95 dived into how fault injection testing works best for DDB workloads.
Itâs valenties day, and the love for Serverless is 1MB max payload across Lambda, SQS, and now even Amazon EventBridge.
For developers, this means the days of âclaim-checkâ patternsâwhere youâd store a large payload in S3 and just pass a pointer in the eventâare over for many common use cases. You can now ingest much richer data directly into your Event Bus, from dense LLM prompts and complex Generative AI outputs to high-frequency telemetry signals and massive JSON blobs. By removing the need to split, compress, or externalize your data, your architecture becomes significantly leaner. With EventBridge, SQS, and Lambda all speaking the same â1 MB language,â you can pass these large payloads through your entire serverless pipeline without worrying about a 256 KB bottleneck at the router.
The ânew normalâ eliminates the architectural overhead of the âclaim-checkâ pattern, allowing you to pass rich 1 MB payloadsâlike LLM prompts or dense telemetryâdirectly through a unified EventBridge, SQS, and Lambda pipeline. By removing the need to externalize large data to S3 or chunk it into smaller pieces, you achieve a leaner, faster architecture
â Pick of the month
This monthâs Pick is âDynamoDB data retrievalâ.
Uriel Bittonâs DynamoDB Data Modeling Strategies to Reduce Monthly Costs: Designing for Queries Instead of Data Moving Away from âRelational DBâ and Thinking of a Single Table with GSIs.
Sathiesh Veera shares Things I Wish I Knew Before I Started Using DynamoDB, where the mindset shift is much necessary while understanding how you want to work around with the data, given no JOIN.
Anna Pastushko takes on the question of do you really need single table design for DynamoDB? Addressing how overloaded the queries could end up, while observability for it would be a nightmare.
Jones Zachariah Noel N (author) takes on DynamoDB with PartiQL, which explains how you can still leverage a âSQL-likeâ querying for your DynamoDB, and the part-2 of the series also looks into batch executions.

đ¨âđť Word from the author
Thanks for the support and letâs share more about Serverless!!!
We know that some of the AWS teams were impacted with the downsizing, we have worked with some of them; if your company is hiring, please reach out to the impacted folks.
Iâm open to feedback, so feel free to DM me on LinkedIn for any queries about AWS or Serverless.
If you are looking for any guidance or assistance with learning Serverless, my LinkedIn DMs are open for a chat!
Stay tuned and share with Serverless enthusiasts. Follow The Serverless Terminal on X (formerly Twitter) and Blog.
Until next time, happy building on Serverless!
