Cloud databases allow you to exclude work with the infrastructure. You can raise the require number of nodes in a few minutes in the companys control panel. The solution is fault tolerant and easily scalable. In an emergency backup copies are create to roll back the state of the database for up to seven days. […]
Limitations Performance depends on the volume of incoming information the number of metrics monitore as well as the time lag between writing new data and reading requests Database examples OpenTSDB Prometheus InfluxDB TimescaleB Combine bases This type of database combines SQL and NoSQL approaches to organizing data storage and processing. This class of databases includes […]
The technology is actively use in the construction of analytical systems and services that work with large amounts of data. Speaker bases The figure shows an example of columnar storage of information about fruits. There are three types of fruits apples grapes bananas. All of them are unite in the fruit family. Each fruit has […]
In this case the content of the document may have a different set of properties. For example a directory of user profiles one of them indicate his favorite dish as a preference and the other a video game. Since this information cannot be store in one field due to logical and structural separation they are […]

NoSQL and non relational databases All the […]
Depending on the type the logical structure of the database may have a different description. This difference affects which database is use in the development of a particular product or technology. The simplest types of databases Such databases include a database that stores data with a simple structure for example a list of allowe IP […]
Limitations Hierarchical organization technology does not involve many. To many relationships which means that the data storage system is quite limite. Network databases This technology develops a hierarchical approach by modeling complex relationships between objects. Here children can have more than one parent but the limitations of the hierarchical approach remain. Network database An example […]
With the help of clients they receive detaile feeback and catch bugs that appear only during baptism of fire . In Selectel for example several services are in beta at once Container Registry . If you use Manage Kubernetes store container images in the registry for free. Within one project you can use one registry […]
Often companies are guide by the rule Ill take the server for growth. In the case of a database for example they adhere to the following logic Id rather pay more than move to a new server in six months. However moving can be completely avoide for example in the servers of the cloud platform […]
On relatively small amounts of data these queries will be processe quickly and with an increase in the size of the database they will slow down. The reason lies in the attachment mechanism. It is base on a line by line comparison of two or more tables according to the join condition for example the […]
Increase fault tolerance By optimally organizing the table schema select. And aggregation queries will work with less data and therefore faster than without normalization. By increasing the number of records in the tables over time this will help maintain a positive user experience. Modeling relationships in relational databases. An illustrative example of modeling complex relationships […]
The load is mainly for recording. A separate service reads data from the replica and transfers it to ClickHouse where analytics is built. Thus the company removes part of the load from its database and continues to use a rather modest cloud server for the database. This separation of duties can be attribute to best […]
