Issue Description:
Hello.
I have discovered a performance degradation in the
.concat
function of pandas version 1.5.2. And I notice the repository depends on pandas 1.5.2 inpython/requirements.txt
. I am not sure whether this performance problem in pandas will affect this repository. I found some discussions on pandas GitHub related to this issue, including #50652 and #52685.I also found that
python/tempo/intervals.py
andpython/tempo/tsdf.py
used the influenced api. There may be more files using the influenced api.Suggestion
I would recommend considering an upgrade to a different version of pandas >= 2.1 or exploring other solutions to optimize the performance of
.concat
.Any other workarounds or solutions would be greatly appreciated.
Thank you!
