WebSphere eXtreme Scale Primer, part-3 : concepts

  • Key – A Java object instance that identifies a single cache value
  • Value – A Java object instance that contains the cache data
  • Map – An interface that stores data as key-value pairs
  • MapSet – A collection of maps whose entries are logically related
  • Grid – A collection of map sets
  • Partition – The concept of splitting data into smaller sections
  • Shard – The data in a partition is physically stored in shards.
  • Grid Container – Grid containers host shards
  • Grid Container Server – A grid container server hosts grid containers
  • Catalogue Server – A catalogue server controls grid container servers.

 

 

A grid container server can host many grid containers.
A grid container hosts shards, which can be from one or more grids.
A grid can be spread across many grid containers.
The catalog service places shards in grid containers.
A grid consists of a number of map sets. A map set is partitioned using a key. Each map in the map set is defined by a BackingMap.
A map set is a collection of maps that are typically used together. Many map sets can exist in one grid.
A map holds (grid) data as key value pairs.
A map set consists of a number of partitions. Each partition has a primary shard and N replica shards.

WebSphere eXtreme Scale …… coming soon here

Hi 

I did WebSphere eXtreme Scale training and study last year. 
Thanks to GWC rewards.

Since there is very little information available about this product, Iam planning to run a crash course #KeepAnEyeOnIt

Here are the likely Topics:
1. What is eXtreme Scale
2. Use of extreme scale
3. Key features of eXtreme Scale
4. eXtreme scale terminology
5. eXtreme scale concepts
6. Topologies
7. Installation methods
8. Configuration of eXtreme scale 
9. Deploying code
10. eXtreme Scale APIs.
