Therefore, even when your testing environment is delivering throughput that far exceeds your expected production database performance, a test system that delivers better performance in a HammerDB test will also have the potential to outperform one for your real-world applications. With these caveats,...

To represent database-table data in Python objects, Django uses an intuitive system: A model class represents a database table, and an instance of that class represents a particular record in the database table. To create an object, instantiate it using keyword arguments to the model class, ...
In addition to querying using regular values, there are two functions you can pass in when querying TimeUUID columns to help make filtering by them easier. Note that these functions don’t actually return a value, but instruct the cql interpreter to use the functions in it’s query. classMi...
In this post, we will show an example of using Docker to deploy the HammerDB command line and test a database with minimal effort. Our Linux test system is running a MariaDB 10.10 database with Docker installed, so we are going to use Docker to pull the HammerDB image and run the te...
Last summer, Oracle introduced Oracle Big Data SQL, which can extend Oracle Database security to the entire big data environment. In January of this year, Oracle also gave enterprises a better and less expensive alternative to building Hadoop clusters. Adding to its powerful lineup of big data...
I worked at a small startup. I had product features to release. I wanted to be better at Python and JavaScript, not databases. The database was just not my focus, so it stayed scary. As many of you know, not making changes in the database is never an option. Your database has ...
>>> print e.blog # Doesn't hit the database; uses cached version. FOLLOWING RELATIONSHIPS "BACKWARD" (反向) 如果一个 model A 有 Foreignkey, 那么 A 的 Foreignkey 指向的 model B 的 实例便有一个 Manager 方法。这个 Manager 方法可以返回所有关联的 model A 的实例。
too. When we found out about the “nogil” fork of Python it took a single person less than half a working day to adjust the codebase to use this fork and the results were astonishing. Now we can focus on data acquisition system development rather than fine-tuning data exchange algorithms...
As the HTTP verb for the request is PUT, the request.method property is equal to 'PUT', and therefore, the function will execute the code that parses the JSON data received in the request, creates a Game instance from this data and updates the existing game in the database. If the ...
