Over the years, it looks like AWS has taken various execution engines, bolted on AWS-specific modifications and then
built the Athena service around them.
Thus, Athena is not simply hosted Trino, it's more like a router that routes SQL queries to an execution engine depending
on the query type.
As at 2024-09-10, assuming your Athena workgroup is configured to use "Athena engine version 3", the following engines exist:
Hive:
- Accepts mostly the same syntax as Hadoop / Hive
- Uses backticks to quote identifiers
- Has a distinctive DDL syntax (around things like setting table properties, storage locations etc) that is different from Trino
- Used for *most* DDL, with some exceptions that get routed to the Trino engine instead:
- CREATE [EXTERNAL] TABLE (without AS SELECT)
- ALTER
- DROP
Trino:
- Uses double quotes to quote identifiers
- Used for DDL operations that involve SELECT queries, eg:
- CREATE VIEW
- CREATE TABLE... AS SELECT
- Used for DML operations
- SELECT, INSERT, UPDATE, DELETE, MERGE
The SQLGlot Athena dialect tries to identify which engine a query would be routed to and then uses the parser / generator for that engine
rather than trying to create a universal syntax that can handle both types.
