Hey there, fellow CSV crunchers!
I’m excited to share a new beta version with you, even though it has been a bit slower than anticipated. So, why the delay? Let’s dive in!
The main reason for the slower pace is a significant decision I made: switching from C++ to Python as the foundation of my application. This change may seem like a detour, but it’s actually a strategic investment in the future. By transitioning to Python, I’ll gain the ability to implement features faster and more efficiently in the long run. Python’s vast ecosystem of data-mangling libraries will empower Tablecruncher to handle and process data like never before.
System requirements: requires macOS Mojave, Catalina, Big Sur, Monterey or Ventura (Intel/ARM64)
I want to address a concern that some of you might have regarding the performance of the new Python-based version compared to the previous C++ one. Fact is, the new version is not slower but sometimes even faster! Let me share the numbers with you.
The tasks in the following table were performed on a 1 GB CSV file containing 8.8 million rows and 10 columns on my MacBook Air M1:
|Task||Version 1.6.0||Version Beta 02|
|Sorting by integer||34s||12s|
With this new beta version, I’ve also changed the versioning scheme for Tablecruncher. Instead of the old-fashioned Major.Minor.Patch scheme, Tablecruncher now uses a simple Year.Counter scheme. For example, version 2023.1 is the first version of Tablecruncher published in 2023. Beta versions have a suffix like -beta02.
Stay tuned for more updates!
Happy crunching, Stefan
