* Support for complex user authentication systems, **database connections**, etc.
* **No compromise** with databases, frontends, etc. But easy integration with all of them.

### Unlimited "plug-ins" { #unlimited-plug-ins }

Or in other way, no need for them, import and use the code you need.

a single erasure coding unit within a MinIO deployment. An object is sharded within an erasure set. Erasure set size is automatically calculated based on the number of drives. MinIO supports unlimited number of drives but each erasure set can be up to 16 drives and a minimum of 2 drives.

- We limited the number of drives to 16 for erasure set because, erasure code shards more than 16 can become chatty and do not have any performance advantages. Additionally since 16 drive erasure set gives...

// casting it as uint8 explicitly requires type conversions in multiple places
const numBuckets = 100

// NewLRU returns a new thread-safe cache with expirable entries.
//
// Size parameter set to 0 makes cache of unlimited size, e.g. turns LRU mechanism off.
//
// Providing 0 TTL turns expiring off.
//
// Delete expired entries every 1/100th of ttl value. Goroutine which deletes expired entries runs indefinitely.

* **Никаких компромиссов** с базами данных, интерфейсами и т. д. Но при этом — лёгкая интеграция со всеми ними.

### Нет ограничений на "Плагины" { #unlimited-plug-ins }

Или, другими словами, нет необходимости в них — просто импортируйте и используйте нужный вам код.

* Soporte para sistemas de autenticación de usuario complejos, **conexiones a bases de datos**, etc.
* **Sin compromisos** con bases de datos, frontends, etc. Pero fácil integración con todos ellos.

### "Plug-ins" ilimitados { #unlimited-plug-ins }

O de otra manera, no hay necesidad de ellos, importa y usa el código que necesitas.

* Unterstützung für komplexe Authentifizierungssysteme, **Datenbankverbindungen**, usw.
* **Keine Kompromisse** bei Datenbanken, Frontends, usw., sondern einfache Integration mit allen.

### Unbegrenzte Erweiterungen { #unlimited-plug-ins }

Oder mit anderen Worten, sie werden nicht benötigt. Importieren und nutzen Sie den Code, den Sie brauchen.
