This free online converter lets you convert code from PySpark to Gleam in a click of a button. To use this converter, take the following steps -
| Characteristic | PySpark | Gleam |
|---|---|---|
| Syntax | Pythonic syntax with DataFrame and RDD APIs, similar to pandas but adapted for distributed computing. | Statically typed, functional syntax inspired by Erlang and Elm, with pattern matching and immutable data structures. |
| Paradigm | Distributed data processing using functional programming concepts (map, reduce, filter) on large datasets. | Purely functional programming with strong emphasis on immutability and concurrency, targeting the BEAM VM. |
| Typing | Dynamically typed (Python), with optional type hints in recent versions. | Statically typed with a strong, inferred type system. |
| Performance | High performance for big data workloads due to distributed execution on Spark clusters. | Efficient for concurrent and fault-tolerant applications on the BEAM VM, but not designed for big data processing. |
| Libraries and frameworks | Rich ecosystem for data processing, machine learning (MLlib), and integration with Hadoop, Hive, etc. | Smaller ecosystem, mainly focused on building reliable backend services and leveraging Erlang/Elixir libraries. |
| Community and support | Large, mature community with extensive documentation and enterprise support. | Growing but small community, with active development and increasing resources. |
| Learning curve | Moderate for Python users, but distributed computing concepts can be challenging. | Steep for those new to functional programming and static typing, but approachable for those familiar with BEAM languages. |
