01 data sources - mergen-sergio/DBest GitHub Wiki

In DBest, a data source refers to a collection of records, where each record consists of a set of columns. Each column has a specific data type that determines the kind of values it can store.

The following primitive data types are supported:
STRING, INT, LONG, DOUBLE, FLOAT, and BOOLEAN.

DBest currently supports three main types of data sources:

1. CSV Files
2. Memory Tables
3. Proprietary Format (B+ Tree)

The proprietary format uses indexed .dat files. In this format:

• A set of columns is designated as keys.
• The remaining columns are stored as values.

This indexing structure enables:

• Reading records in key order.
• Efficient lookups for both equality and range queries on key columns.
