Synthetisation Performance

The faster you can synthesise your CDKTF code, the faster you can deploy it. This page focusse on how to optimise your CDK for Terraform performance.

Typescript

In Typescript the main bottleneck for synthetisation performance is the time it takes ts-node or tsc to compile your code. The easiest way to improve this is using explicit resource imports like import { MyResource } from '@cdktf/provider-my-provider/lib/my-resource' instead of star imports like import * as myProvider from '@cdktf/provider-my-provider'. Another option is to use a bundler without typechecking like tsx or swc to compile your code. These are typically a lot faster than tsc or ts-node, but you will get no typechecking.

Python

Python is out of the box optimized for synthetisation performance, there a no known steps to improve the synthetisation performance.

Java

To improve the synthetisation performance of Java we recommend using Gradle over Maven. We could observe an improvement for an example using the AWS provider from 3m 30s to 30s after the initial compilation. To migrate to Gradle we recommend creating a new CDKTF project and copying the code over.

C#
