Here’s the difference between Alation and Debezium. The comparison is based on pricing, deployment, business model, and other important factors.
Alation provides a data cataloging platform. It automatically builds a catalog of useful data documentation, covering all of the data sources, and allows users to collaborate and work on the data. It processes enterprise unstructured data by centralizing knowledge into a single place using machine learning and human analysts. The search can be made using keywords in plain English. Enables users to access relevant information (including experts, lineage, keys and indexes, relevant queries) and documentation on all tables, across the organization’s data sources. The clients include PepsiCo, Dow, Fox Networks, BMW and others.
Debezium is an open source distributed platform for change data capture. Start it up, point it at databases, and apps can start responding to all of the inserts, updates, and deletes that other apps commit to databases. Debezium is durable and fast, so apps can respond quickly and never miss an event, even when things go wrong.
