Build a high-availability MongoDB cluster (i)--Configure MongoDBPosted on 171 months, by Lanceyan | 9 ReviewsIn the age of big data, traditional relational databases need to be able to have higher services to solve the challenges of high concurrency and read-write, efficient storage of massive data, high scalabil
Maintaining the longest normal system running time is increasingly important for the on-demand computing success. Unfortunately, many off-the-shelf high availability (HA) solutions are expensive and require specialized technologies. Five articles in this series will provide a cheap alternative to obtaining HA services using publicly available software.
Detailed steps in this series will show you how to buil

:
Simple to implement
Maximum efficiency without the need for inter-threading collaboration
Easiest to implement sequential processing of messages within each partition
Disadvantages:
Each kafkaconsumer maintains a TCP connection to the cluster
The number of threads cannot exceed partition
The amount of data pulled by each batch becomes smaller and has a certain impact on throughput
2. Decoupling, 1 consumer threads are responsible for pulling messages
Common Features of keepalived High AvailabilityKeepalived is used to detect the status of a web server. If a web server crashes or fails to work, Keepalived will detect it and remove the faulty web server from the system, when the web server is working normally, Keepalived automatically adds the web server to the server group. All these tasks are completed automatically without manual interference. All you need to do is to manually repair the faulty w

High Availability is a key requirement for important database applications. IBM DB2 9.5 provides many features to meet this requirement. If you are not familiar with DB2 on the distributed platform, or have been using it for a while, you may find this set of processing availability features confusing.

MHA is a Mysql failover solution written by Mysql experts in Japan using Perl to ensure high Database Availability. Its function is to implement master Mysql failover within 0 to 30 s, MHA failover can help us solve the consistency problem of slave database data and maximize the recovery of data after the fault. This article is based on the Mysql master-slave architecture

I have previously written an article on mongodb multi-server configuration, which is in master-slave mode. For details, refer to mongodb master-slave configuration. Master-slave mode, cannot automatically implement failover and recovery. Therefore, we recommend that you use mongodb replicaset to achieve high availability of multiple servers. It seems to me that replicaset comes with h.
