Concept ® - Tous droits réservés. For more information, see the full release notes. Additional redundancy in the database cluster also minimizes the risk of data loss. We currently offer three database engines: PostgreSQL, Redis, and MySQL. Database clusters must have at least one standby node to be highly available because standby nodes provide redundancy for the primary node: Without standby nodes, the primary node is a single point of failure, so the cluster is not highly available. Provisioning a new replacement node takes time, but failing over to a standby node is immediate. Read-only nodes are not considered part of the cluster. Cluster Configuration. Managed databases are multi-region and scalable, and their automated failover means even single-node plans add resiliency to your infrastructure.

Global SQL modes affect the SQL syntax MySQL supports and the data validation checks it performs. The ADF contributes to poverty reduction and economic and social development in the least developed African countries by providing concessional funding for projects and programs, as well as technical assistance for studies and capacity-building activities. With two standby nodes, the cluster is highly available and very resilient against downtime. High availability requires redundancy in addition to automatic failover. In effect, under the DAI Policy, all information held by the Bank will be made public unless there is a compelling reason for confidentiality.

MySQL is an open source, object-relational database built with speed and reliability in mind. They provide geographically distinct, horizontal read scaling. It has support for rich data types, atomic operations, and Lua scripting. Standby nodes are copies of the primary node that automatically take over if the primary node fails. Its large and active developer community has created many third-party applications, tools, and libraries that expand MySQL's functionality. Read-only nodes can be added to a cluster at any time. Read-only nodes are copies of the primary node that process queries and return results but cannot make changes to the database itself. © 2020 Arcadis T.O.E.

When you create a new managed database cluster, the cluster is placed in a VPC network by default. In other words, the effect of a primary node's failure on service availability depends on the cluster configuration. However, the write-ahead log backs up every five minutes, so the most recent writes to the database may be lost if the cluster needs to recover this way. Its concurrency support makes it fully ACID compliant, and it supports dynamic loading and catalog-driven operations to let users customize its data types, functions, and more.
