I would like to write several files into ~50 GB chunks instead of one single file for ease of reading. I believe by default, if a TTree is larger than 100GB (the default max tree size) a new file is created with “*_n.root” in its name. I am using pyroot and RDataFrame but I am having an issue which I’m not sure it is reproducible. When using RDataFrame to snapshot and it hits the max tree size, it produces a file called “original_filename_1.root” but it also deletes the original file? Is this normal behaviour?
I wasn’t sure if this was an error as it was a grid job (hence not easy to reproduce).
