For geometry values, MySQL distinguishes between the concepts of syntactically well-formed and geometrically valid. Spatial import functions that parse WKT or WKB values raise an error for attempts to create a geometry that is not syntactically ...
https://dev.mysql.com/doc/refman/5.7/en/gis-class-geometry.html
This value identifies the geometry's associated spatial reference system that describes the coordinate space in which the geometry object is defined. This is the bounding geometry, formed by the minimum and maximum (X,Y) coordinates: ((MINX MINY, ...

This section explains how to create a replication group with three MySQL Server instances, each running on a different host machine. Figure 17.4 Group Architecture This tutorial explains how to get and deploy MySQL Server with the Group Replication ... Each of the MySQL server instances in a group can run on an independent physical host machine, which is the recommended way to deploy Group ...

This has direct impact on the number of failures the system can tolerate without compromising itself and its overall functionality. In practice this means that to tolerate one failure the group must have three servers in it. MySQL Group Replication ...

By configuring this wait to be a little longer (doing an active wait) before actually going to sleep can prove to be beneficial in some cases. This is because the alternative is for the operating system to switch out the GCT from the processor and ... The group communication thread (GCT) runs in a loop while the Group Replication plugin is ...

Before getting into the details of MySQL Group Replication, this section introduces some background concepts and an overview of how things work. This provides some context to help understand what is required for Group Replication and what the ...
https://dev.mysql.com/doc/refman/5.7/en/group-replication-the-group.html
The group membership service described at Section 17.1.3.1, “Group Membership” powers all of this. In MySQL Group Replication, a set of servers forms a replication group. A group has a name, which takes the form of a UUID. The group is dynamic ...

This means that if the data to transfer is too big at phase 1, the server may take a very long time to recover. This minimizes the length of phase 1 and reduces the impact on the donor server, since it has to save and transfer less binary logs. It ...
https://dev.mysql.com/doc/refman/5.7/en/group-replication-use-cases.html
A connector, load balancer, router, or some form of middleware are more suitable to deal with this issue. Group Replication enables you to create fault-tolerant systems with redundancy by replicating the system state to a set of servers. Even if ...

This resulted in a new SQL interface to our database but with almost the same API interface as mSQL. This API was designed to enable third-party code that was written for use with mSQL to be ported easily for use with MySQL. We started out with the ...
