Count Providers ​

Django provides two built-in count_provider implementations. See Count provider for the common interface.

DjangoCountProvider ​

DjangoCountProvider is used by default and performs an exact COUNT(*) query.

python
django.DjangoAdmin(
    model=Order,
    count_provider=django.DjangoCountProvider(),
)

TIP

Use max_count to limit exact count queries. When exceeded, the table displays {max_count}+ and page count is unavailable.

PostgresCounter ​

Optimized provider for PostgreSQL:

  • Without filters, it reads the count from pg_class.reltuples and displays ~19000000.
  • Filtered queries are capped by BRILLIANCE_ADMIN_CAPPED_COUNT_LIMIT, default 1000.
python
django.DjangoAdmin(
    ...
    count_provider=django.PostgresCounter(),
)
