Possible disadvantages of LeetCode

  • Paid Subscription
    While LeetCode offers many resources for free, a premium subscription is required to access some advanced features, company-specific questions, additional test cases, and certain problem solutions.
  • Steep Learning Curve
    For beginners, the wide range of problem difficulties and the complexity of some problems can be intimidating and may require a significant amount of time and effort to get up to speed.
  • Limited Technology Coverage
    LeetCode mainly focuses on algorithm and data structure problems and doesn't cover other technical aspects like system design, databases, or front-end development as comprehensively.
  • Variable Quality of Community Solutions
    While the community is active, the quality of user-contributed solutions and explanations can vary significantly, and some may not follow best practices or be optimal.
  • Platform Performance Issues
    Some users report occasional performance issues such as slow loading times or glitches during peak usage times, which can be frustrating during practice or contests.
  • Overemphasis on Coding
    LeetCode's focus is predominantly on coding problems, which might lead some users to neglect other important skills required for technical interviews, such as communication and problem-solving in real-world scenarios.

Redash features and specs

  • Scalability
    Redash might face performance issues when dealing with very large datasets or a high number of simultaneous queries.

    Being an open-source product, Redash relies heavily on community support, which can be inconsistent and slower compared to commercial products with dedicated support teams.
  • Advanced Features
    Compared to more established BI tools, Redash may lack some advanced features and functionalities like detailed user access controls and more complex data transformations.
  • Documentation
    The documentation for Redash can be lacking or outdated, making it challenging for users to find the information they need.

  • Tool or service for querying and exposing database through API
    I am looking for service or tool similiar to Metabase or Redash that allows me to add data source - for example Postgres connection, and create raw SQL queries that can be shared or exposed through API. So instead of keeping raw SQL code somewhere, my other service would call this tool e.g. http://microservice/query=1?param1=xx&page=2 and get the results from the DB. These calls are internal only and part of ETL... Source: almost 3 years ago
  • Did anyone try Openblocks for multi-tenant client reporting?
    I have tried Metabase, Redash beore (both self hosted open source versions), from my experience I find Metabase a bit easy to work with. Source: about 3 years ago
  • Best apps for transitioning from Spreadsheets to SQLite?
    Regarding visualization tools, sqliteviz has proven to be the best I've found so far. Their web app runs locally but has some trackers, so I run it locally via a simple, static HTTP server. Falcon and Redash seem like overkill for my needs. Source: about 3 years ago
  • Framework Laptops are now Thunderbolt 4 certified
    In addition to metabase there are redash[0] and apache superset[1]. They are more or less similar to metabase with some different quirks. You can also visualize quite a bit of data in grafana[2] as well.
