# Glossary | ||

||
## Persistent source schema | ||
Many tests generate and execute SQL that depend on tables containing test data. By default, a | ||
pytest fixture creates a temporary schema and populates it with the tables that are required by | ||
the tests. This schema is referred to the source schema. Creating the source schema (and | ||
the associated tables) can be a slow process for some SQL engines. Since these tables generally | ||
do not change often, functionality was added to use a source schema that is assumed to already | ||
exist when running tests and persists between runs (a persistent source schema). In addition, | ||
functionality was added to create the persistent source schema based on table definitions in the | ||
repo. Because the name of the source schema is generated based on the hash of the data that's | ||
supposed to be in the schema, the creating and populating the persistent source schema should | ||
not be done concurrently as there are race conditions when creating tables and inserting data. |
