We can say that the Kafka rebalancing is the process of plotting the partitions to consumers in a specific manner, when rebalancing is going on then one partition can be handed over to the consumer in an incremental way, let us understand it with the help of the following figure, From the...
Let’s come back to databases for a bit. There is a facinating duality between a log of changes and a table. The log is similar to the list of all credits and debits and bank processes; a table is all the current account balances. If you have a log of changes, you can apply these...

其实在linkedin中,就是基于Kafka系统,我们使用Kafka系统有2年时间,虽然也类似这样使用,但是对它的作用到此才理解的那么深刻 1. 首先用于子系统间的解耦合,每个子系统都只知道从cental log中异步的读写数据,而不需要知道其他的子系统 2. kafka系统作为中间的buffer,可以调节各个子系统之间的produce和consume速度上的差...
The log is the natural data structure for handling data flow between systems. The recipe is very simple: Take all the organization's data and put it into acentral logforreal-time subscription. 其实在linkedin中,就是基于Kafka系统,我们使用Kafka系统有2年时间,虽然也类似这样使用,但是对它的作用到此...
可以看出kafka系统在linkedin中的重要地位,不光是data aggregation,而是整个系统的核心 Part One: What Is a Log? log定义 很简单的结构,最关键的属性是,append-only和有序性 A log is perhaps the simplest possible storage abstraction. It is an append-only, totally-ordered sequence of records ordered by...
The similarity goes right down to the way partitioning is handled, data is retained, and the fairly odd split in the Kafka API between high- and low-level consumers. I was pretty happy about this. A sign you've created a good infrastructure abstraction is that AWS of...

be thought of as the "timestamp" of the entry. Describing this ordering as a notion of time seems a bit odd at first, but it has the convenient property that it is decoupled from any particular physical clock. This property will turn out to be essential as we get to distributed systems...
