[](#darkredislistbundle-)

Symfony2 bundle which allows you to store part of doctrine entities data in Redis. For more information please read text below.

### How do we manage lists at MySQL:

[](#how-do-we-manage-lists-at-mysql)

- write query, for example 'SELECT a FROM MyTestBundle:Post a ORDER BY a.created\_at'
- use doctrine repository

then we can pass it to the paginator, but no need to talk about it now.

### But I need more functionality to those lists:

[](#but-i-need-more-functionality-to-those-lists)

- combine few entity types at one list\\query
- retrieve real-time result
- use permanent cache for each entitiy
- it's should be fast

### Introducing to Redis Lists

[](#introducing-to-redis-lists)

Redis List — it's structured data, that is stored in Redis hashes (do not confuse native Redis lists with ours). Okay, let's learn more about this.

### What Redis List is?

[](#what-redis-list-is)

Each list have name, for example — 'View', each element of this hash has unique ID and it contains some value.

Here is example of Redis List:

```
Hash  ID   Value
View — 1 — SonataBadBundle:Post;1
View — 2 — SonataBadBundle:Post;2
View — 3 — SonataBadBundle:Post;3
View — 4 — KnpGoodBundle:Article;1
View — 5 — MyPromoBundle:Promo;1

```

So, as you can see that each hash:

- starts from 1 id
- all ids are holistic (count of all elements = last element id)

Okay, but how it's can satisfy my requirements?

```
Each element of Redis List contains information about entities — repository name, id.
I can fetch those entities through repository, and then cache it in Memcached for example.

```

### Features which it gives to you:

[](#features-which-it-gives-to-you)

- real-time list result
- can store entities in cache permanently
- if new element passed to list, no need to reload old entities from DB
- it allows to list a few types of entities as one list
- it allows to list random entities from list freely, cuz ids are holistic, and also no need to fetch them from DB

Installation
