Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Conjecture is primarily built for Scala, which may pose a barrier for developers more familiar with other languages such as Python or Java.
Setting up Conjecture requires a deep understanding of both Scalding and the Hadoop ecosystem, which can be time-consuming for new users.
The open-source nature of Conjecture means that it relies heavily on a smaller community for support and contributions, leading to potentially sparse documentation and slower issue resolution times.
