Introducing Lambdora

I am thrilled to introduce Lambdora - a service that turns change data capture (CDC) events into a clear, queryable timeline of how your data evolves over time.

What is Lambdora?

Lambdora integrates into your existing CDC pipeline (using Debezium and Kafka) and consumes CDC events from your systems. It persistently records all data changes - creates, updates, and deletes - in a structured and queryable form.

Based on these events, Lambdora builds a historical timeline for each data entity. This timeline can be queried across specific time ranges, filtered by operation types, or narrowed down to changes affecting particular fields. The result is a clear and reliable view of how your data evolves over time and what exactly changed at each step.

Think of it as a time machine for your database.

Key Features

• Field-level change history - See exactly what changed, from what value, to what value
• Time-travel queries - Query an entity's state at any point in time
• Queryable change timelines - Filter by time range, operation type, or affected fields
• Automated and manual compaction - Keep storage and performance under control
• Entity-level statistics - Track first/last change timestamps and event counts
• Interactive UI - Visual exploration of entity history and changes
