Redis-OM Lambda CDK

Overview of My Submission

This sample shows how to define a Lambda function which uses Redis-om via AWS Cloud Development Kit. This is a fork of prisma-lambda-cdk sample repo which replaces mysql/postgres with redis stack & prisma with Redis-om.

By this sample, you can see how a Lambda function which uses Redis OM can be deployed with CDK, how indexes can be created from Lambda, and how Redis OM works in Lambda.

Build and deploy a Lambda function with Redis OM by AWS Cloud Development Kit.

Redis-OM Lambda CDK Sample Application

This sample shows how to define a Lambda function which uses Redis-om via AWS Cloud Development Kit. This is a fork of prisma-lambda-cdk sample repo which replaces mysql/postgres with redis stack & prisma with Redis-om.

Redis OM is an open source object mapping, search etc library for Redis written in Typescript & very useful with its developer friendly API.

By this sample, you can see how a Lambda function which uses Redis OM can be deployed with CDK, how indexes can be created from Lambda, and how Redis OM works in Lambda.

How it works

Architecture

This sample consists of the following AWS services:

• Amazon VPC
• Redis Cloud (Amazon doesn't offer redis stack yet)
• AWS Lambda

There're two Lambda functions:

1. a function that reads and writes records from/to Redis handler.ts
2. a function that sets up the index for Request entity migration-runner.ts

Performance Benchmarks

I did the testing for both lambda functions by creating a url for them and then using k6 to test them.
Terminology:

• VU Count: Number of concurrent requests being made
• Duration: The duration for which test was run
• Function type: Type of Lambda function executed
• Prisma p95: p95 response time of prisma lambda function
• Redis OM p95: p95 response time of redis om lambda function
• Prisma p90: p90 response time of prisma lambda function
• Redis OM 90: p90 response time of redis om lambda function
• Prisma AVG: Avg response time of prisma lambda function
• Redis OM AVG: Avg response time of redis om lambda function

VU Count	Duration	Function Type	Prisma p95	Redis OM P95	Prisma p90	Redis OM p90	Prisma AVG	Redis OM AVG	Prisma Failed Reqs	Redis OM Failed Reqs
10	30s	Handler - Create Data	91.99 ms	67.56 ms	74.57 ms	60.4 ms	71.56 ms	57.16 ms	0	0
20	30s	Handler - Create Data	89.35ms	65.7ms	74ms	59.19ms	70.56ms	54.73ms	26.60%	24.66%
20	30s	Handler - Retrieve Data	698.56ms	516.26ms	600.07ms	394.06ms	547.38ms	344.9ms	0	0
20	30s	Migration Runner	10.87s	3.16s	8.95s	2.93s	7.8s	2.67s	0	0

From these stats we can infer that there's a signifact performance boost when migrating schemas using Redis OM instead of Prisma.
Reads from Redis are also faster than Mysql & while not much but writes are faster as well.
