While transactions desires isolation, too strong isolation may offset the performance benefit from execution concurrency. In practice, isolation is defined at different levels with trade-offs between consistency and concurrency. The applicability of each isolation level is determined by the specific scenario targeted.
A request to storage systems often involves multiple operations, while the lack of integrity among individual operations complicates the management of a storage system. To address that, transactions are used as a container to encapsulate multiple individual operations and facilitate their management.
Divide and conquer is a strategy that helps simplify solving a complex problem. It begins by dividing a problem into subproblems. It then keeps doing that until the subproblem is trivial to solve. In the end the outcome of each subproblem are assembled backwards and eventually lead to the result of the whole problem.
Manually renewing certificates every three months is not going to be sustainable. Fortunately, there is the experience shared for automating the certificate renewal under GitLab. The basic idea is to apply the same operation of the manual certificate generation described in the previous article, but via the automation strategy with the GitLab pipeline schedule. Here I recompiled the scripts from the original article to not include any domain specific content, which allows them to be directly applied to any repositories (with domain specific variables defined in the pipeline setting).
The default HTTPS support by GitLab will be unavailable with custom domains. Fortunately, there is the solution to add HTTPS back for free.
While you can edit pages online in GitLab (e.g., through Web IDE, which also allows to preview Markdown pages), a local development environment of Hugo provides the best support of “what you see is what you get”.
