DuneSQL Features

DuneSQL offers several useful features for working with blockchain data:
  1. Blockchain varbinary data types: Designed for storing addresses, hashes, and other encoded data.
  2. Native support for uint256 and int256 data types: Ideal for handling large numbers commonly found in blockchain data, with built-in functions for ease of use.
  3. Columnar storage format Optimized for fast reads, this format organizes data in columns rather than rows, enabling quick access to single columns for aggregation or filtering.
  4. Querying a query: DuneSQL allows you to query a query, which is great for creating reusable queries, building up complex queries, and reusing queries as views.
