QEC note taking is a method described by Cal Newport in the book student which stands for question, evidence, and conclusion. It aims to make notes easy to review, identify how much evidence actually supports a claim, and make note taking fast either handwritten or typed.

Steps

  1. Question: List questions from the text or your own questions about the material
  2. Evidence: Read to find evidence that answers the question
  3. Conclusion: Summarize the evidence into a statement

Catalog

You may think of Iceberg as a format for managing data in a single table, but the Iceberg library needs a way to keep track of those tables by name. Tasks like creating, dropping, and renaming tables are the responsibility of a catalog. Catalogs manage a collection of tables that are usually grouped into namespaces. The most important responsibility of a catalog is tracking a table’s current metadata, which is provided by the catalog when you load a table.

The first step when using an Iceberg client is almost always initializing and configuring a catalog. The configured catalog is then used by compute engines to execute catalog operations. Multiple types of compute engines using a shared Iceberg catalog allows them to share a common data layer.

A catalog is almost always configured through the processing engine which passes along a set of properties during initialization. Different processing engines have different ways to configure a catalog. When configuring a catalog, it’s always best to refer to the Iceberg documentation as well as the docs for the specific processing engine being used. Ultimately, these configurations boil down to a common set of catalog properties that will be passed to configure the Iceberg catalog.
