entire cluster has enough capacity, you can add unlimited data to the previous topic partition. if your cluster starts to have no capacity, you simply add a storage node to the cluster, and pulsar will start to automatically use the new storage node without rebalancing the existing data partition. However, if you keep accumulating historical data in bookkeeper, the overhead of the entire cluster becomes expensive.Pulsar addresses the tradeoff between capacity and overhead by providing tiered st

been able to solve a lot of Java about the ' out of memory ' or GC problems, then why we use the ' off-heap ' technology, 1. Very large JVM will take a long time to start, and the cost of GC will be very high2. Heap is required to copy at least once while writing disk or network, while off-heap can implement zero copy3. Off-heap memory is process-shared, JVM process crash does not lose data The opposite question is also valid. Why should Flink ever don't use off-heap memory? On-heap

What China Telecom needs to do is to speed up deployment and deploy VoLTE at the same time, so as to finish the work to be done in advance. Mobile has an obvious first-mover advantage in 4G, and its 4g construction speed is no small hit. If we want to compete with mobile and at least remain undefeated, first of all, telecom at least to achieve the same construction speed to maintain a certain

, under the condition of China's national conditions, the access rate per user is more than 2 Mb/s, FTTH is cheaper. The higher the access rate, the cheaper the FTTH. Less than 2 Mb/s for each user, making LTE more cost-effective. Wei leping said that China Telecom will use LTE and FTTH as ~ How to maximize the features and advantages of these two technologies to form a seamless broadband network is a major
