Question 1

How to use JSLT with Apache Kafka Connect?

Accepted Answer

JSLT can be implemented as a custom Single Message Transform in Kafka Connect; examples and integrations are documented in the README for transforming JSON payloads in data streams.

Question 2

JSLT vs jq: which is better for JSON processing?

Accepted Answer

JSLT is more powerful for complex transformations and Java integration, while jq is lighter and better for quick command-line queries; choose based on your ecosystem and transformation complexity.

Question 3

How to write custom functions in JSLT?

Accepted Answer

Implement the ExtensionFunction interface in Java and register it with the Parser; the extensions tutorial provides step-by-step guidance for adding tailored logic.

Question 4

Does JSLT support error handling for invalid JSON?

Accepted Answer

JSLT relies on Jackson for JSON parsing, so it handles invalid input by throwing exceptions; you need to manage errors externally in your Java code.

Question 5

What are the performance benchmarks for JSLT transformations?

Accepted Answer

While production-proven at scale, specific benchmarks aren't provided; performance depends on expression complexity and Java environment, so testing with your data is advised.

Question 6

How to integrate JSLT in a Spring Boot application?

Accepted Answer

Add JSLT as a Maven dependency and use the Parser.compileString method to apply transformations; the API introduction and javadoc offer integration examples.
