The new ezcCacheStack class in the eZ Cache component provides an automatic way of realizing this. You simply stack together an arbitrary number of storages. The stack will store every item into all of the stacked caches. You can configure how many items may reside in a storage. A replacement strategy class takes care about purging a certain number items in case a storage runs full. On restore, the stack will fetch the desired item from the topmost cache it is still stored in.
Replacement strategies shipped with the eZ Cache component provide you with 2 well-known cache algorithms: Least Recently Used (LRU) and Least Frequently Used (LFU).
The daily stand-up meeting (also known as a "daily scrum", a "daily huddle", a "morning roll-call", etc.) is simple to describe: the whole team meets every day for a quick status update. We stand up to keep the meeting short. That's it. But this short definition does not really tell you the subtle details that distinguish a good stand-up from a bad one.
Given the apparent simplicity of stand-ups, I was quite surprised the first time I saw one that wasn't working. It was immediately obvious to me what was wrong but I realised that it was not obvious to the team. I realised that my team was not aware of the underlying principles and details that would allowed them to diagnose and solve problems with stand-ups.
This blog presents a new toolkit to assist in Dimensioning of MySQL Cluster. The toolkit consists of two parts:
