MySQL sync versions and configurations
Versions of
MySQL semi-sync version 8 is supported.
Node configurations
When creating a MySQL sync cloud database cluster, you can select the number of virtual processor cores (vCPU), the amount of memory (RAM) and the size of local disk for the nodes.
Two types of configurations are available:
- fixed-configurations — lineups that are characterized by resource ratios and specifications;
- arbitrary configurations — any resource ratio can be specified.
Processors used depends on the selected configuration.
Once the cluster is created, you can change node configuration.
Available processors
The prebuilt and custom configuration lines differentiate the available processors. Processor frequency affects the speed of processing user requests, executing complex algorithms and data operations.
You can view the availability of configurations in regions in the Cloud Databases availability matrix.
*
When the cloud server load is 100%, the processor operates with Turbo Boost technology and a maximum frequency of 3.60 GHz. Since the processor is emulated, only the 3.00 GHz frequency will be displayed during testing.
Fixed configurations
You can view the availability of configurations in regions in the Cloud Databases availability matrix.
Standard Line
A line of fixed configurations with a balanced 1:4 vCPU:RAM resource allocation (except for entry-level and maximum configurations). Intel® Xeon® Scalable or AMD EPYC™ 2.2-2.4 GHz processors are used. You can see a comparison of processor frequencies in different configurations in the Available-processors table.
HighFreq Line
Fixed high-performance cloud server configurations. Intel® Xeon® Gold 6354 processors are used, with CPU speeds up to 3.6 GHz and memory speeds up to 3,200 MHz. You can see a comparison of processor frequencies in different configurations in the Available-processors table.
Arbitrary configurations
In arbitrary configurations, you can select the number of resources for cluster nodes:
- vCPU — 1 to 8;
- RAM — 4GB to 64GB;
- Local disk — 32 GB to 512 GB or 1 TB depending on the pool. On the local disk, about 5 GB is reserved for the operating system, service components, and log storage. The rest of the volume is available to host databases.
