Liquibase features and specs

  • Version Control Integration
    Liquibase supports integration with source control systems such as Git, SVN, and Mercurial, making it easier to track changes, revert to previous versions, and collaborate with team members.
  • Database Agnostic
    Liquibase is compatible with a variety of databases including MySQL, PostgreSQL, Oracle, SQL Server, and others, making it versatile for different projects.
  • Automated Change Management
    The tool automatically manages database changes and applies changesets using a standardized process, reducing manual management and errors.
  • Change History Tracking
    Liquibase keeps a detailed history of all applied changes, allowing for easy audit and rollbacks when necessary.
  • Flexible Configuration
    Liquibase offers multiple ways to define database changes, including XML, YAML, JSON, and SQL, providing flexibility based on developer preferences.
  • Community and Support
    Liquibase has a strong community and comprehensive documentation, as well as commercial support options for enterprises.

Possible disadvantages of Liquibase

  • Learning Curve
    For newcomers, there can be a significant learning curve to fully understand and effectively use Liquibase, especially if they are not familiar with database version control concepts.
  • Performance Overhead
    Running Liquibase checks and updates can add performance overhead, especially in large-scale environments with many changesets.
  • Complexity in Large Projects
    Managing complex database schemas with many interdependent changes can become complicated and may require meticulous planning and organization.
  • Limited GUI Tools
    While Liquibase is powerful, its command-line interface may be less intuitive for some users compared to other tools that offer robust graphical user interfaces.
  • Compatibility Issues
    Occasionally, certain database-specific features or custom implementations may not be fully supported by Liquibase, leading to potential compatibility issues.
  • Commercial Licensing Costs
    While the core version is open-source, enterprises may require commercial licenses for advanced features, which can add to the overall cost.

Scrapy features and specs

  • Efficiency
    Scrapy is designed to be efficient and robust, capable of handling multiple tasks simultaneously and scraping large websites in a fast and reliable manner.
  • Built-in Tooling
    Scrapy comes with built-in tools for handling common tasks such as following links, extracting data using XPath and CSS, and exporting data in a variety of formats.
  • Customization
    Scrapy offers extensive customization options, allowing users to build complex spiders and modify their behavior through middleware and pipelines.
  • Python Integration
    Being a Python framework, Scrapy integrates seamlessly with the Python ecosystem, enabling the use of libraries like Pandas, NumPy, and others to process and analyze scraped data.
  • Community Support
    Scrapy has a large and active community, providing extensive documentation, tutorials, and third-party extensions to enhance functionality.
  • Asynchronous Processing
    Scrapy’s asynchronous processing model enhances performance by allowing multiple concurrent requests, reducing the time required for crawling sites.

Possible disadvantages of Scrapy

  • Steep Learning Curve
    For beginners, Scrapy's comprehensive feature set and the need for understanding concepts like XPath and CSS selectors can be challenging.
  • Resource Intensive
    Scrapy can be resource-intensive, potentially consuming significant memory and CPU, which can be problematic for scraping very large websites or running multiple spiders simultaneously.
  • Debugging Complexity
    Debugging Scrapy projects can be complex due to its asynchronous nature and the multiple layers of middleware and pipelines that need to be understood.
  • Overhead for Small Projects
    For simple or small-scale scraping tasks, the overhead of setting up and configuring a Scrapy project might be excessive, with simpler alternatives being more suitable.
  • Limited JavaScript Support
    Scrapy's out-of-the-box support for JavaScript-heavy websites is limited, requiring additional tools like Splash or Selenium, which can complicate the setup.
  • Dependency Management
    Managing Scrapy's dependencies and compatibility with other Python packages can sometimes be challenging, leading to potential conflicts and maintenance overhead.

  • How do you guys go about the persistence layer?
    As far as keeping track of domain changes you can store DDL files in version control like you mention or use tools like Flyway (https://flywaydb.org) or Liquidbase (https://liquibase.org) which takes care of database migrations. Source: about 3 years ago
  • How do you guys go about the persistence layer? (x-post)
    I just use SQL directly (or something like JOOQ). For database migrations I use Liquibase. Source: about 3 years ago
  • Where questioning the scale of a company and its clients its seen bad
    Regarding the migrations, there are tools such as https://liquibase.org/ or FlyAway that handle this. Heck, you can even use an ORM that has a migration baked-in but that defeats the purpose of having the migrations in a separate project. Source: about 3 years ago
  • State based change management tool for Snowflake
    I've trialled schemachange and liquibase which are change script based tools. I've ruled out a whole load of other tools that are either change script based tools or don't support Snowflake, including the following:. Source: over 3 years ago
  • Learning SQL and using dll (CREATE,DROP,ALTER)
    Nowadays I prefer to automate database updates and deployment, using Liquibase and its relational database vendor agnostic syntax for that. Especially on production systems. But on local dev environments, I can still use the occasional SQL in a pinch. Source: over 3 years ago

  • Current problems and mistakes of web scraping in Python and tricks to solve them!
    One might ask, what about Scrapy? I'll be honest: I don't really keep up with their updates. But I haven't heard about Zyte doing anything to bypass TLS fingerprinting. So out of the box Scrapy will also be blocked, but nothing is stopping you from using curl_cffi in your Scrapy Spider. - Source: dev.to / 10 months ago

  • Scrapy Vs. Crawlee
    Scrapy is an open-source Python-based web scraping framework that extracts data from websites. With Scrapy, you create spiders, which are autonomous scripts to download and process web content. The limitation of Scrapy is that it does not work very well with JavaScript rendered websites, as it was designed for static HTML pages. We will do a comparison later in the article about this. - Source: dev.to / about 1 year ago
