0.0.6

Breaking Changes

SQLModel no longer creates indexes by default for every column, indexes are now opt-in. You can read more about it in PR #205.

Before this change, if you had a model like this:

from typing import Optional

from sqlmodel import Field, SQLModel


class Hero(SQLModel, table=True):
    id: Optional[int] = Field(default=None, primary_key=True)
    name: str
    secret_name: str
    age: Optional[int] = None

...when creating the tables, SQLModel version 0.0.5 and below, would also create an index for name, one for secret_name, and one for age (id is the primary key, so it doesn't need an additional index).

If you depended on having an index for each one of those columns, now you can (and would have to) define them explicitly:

class Hero(SQLModel, table=True):
    id: Optional[int] = Field(default=None, primary_key=True)
    name: str = Field(index=True)
    secret_name: str = Field(index=True)
    age: Optional[int] = Field(default=None, index=True)

There's a high chance you don't need indexes for all the columns. For example, you might only need indexes for name and age, but not for secret_name. In that case, you could define the model as:

class Hero(SQLModel, table=True):
    id: Optional[int] = Field(default=None, primary_key=True)
    name: str = Field(index=True)
    secret_name: str
    age: Optional[int] = Field(default=None, index=True)

If you already created your database tables with SQLModel using versions 0.0.5 or below, it would have also created those indexes in the database. In that case, you might want to manually drop (remove) some of those indexes, if they are unnecessary, to avoid the extra cost in performance and space.

Depending on the database you are using, there will be a different way to find the available indexes.

For example, let's say you no longer need the index for secret_name. You could check the current indexes in the database and find the one for secret_name, it could be named ix_hero_secret_name. Then you can remove it with SQL:

DROP INDEX ix_hero_secret_name

or

DROP INDEX ix_hero_secret_name ON hero;

Here's the new, extensive documentation explaining indexes and how to use them: Indexes - Optimize Queries.
