Arrow Files

Arrow file reading and writing is powered by Arrow.jl

read_arrow

read_arrow(path; skip=0, n_max=Inf, col_select=nothing)

This function reads an Arrow (.arrow) file into a DataFrame. The arguments are:

• path: The path to the .arrow file.
• skip: Number of initial rows to skip before reading data. Default is 0.
• n_max: Maximum number of rows to read. Default is Inf (read all rows).
• col_select: Optional vector of symbols or strings to select which columns to load. Default is nothing (load all columns).

write_arrow

write_arrow(df, path)

This function writes a DataFrame to an Arrow (.arrow) file. The arguments are:

• df: The DataFrame to be written to a file.
• path: The path where the .arrow file will be created. If a file at this path already exists, it will be overwritten.
• Additional arguments for writing arrow files are not outlined here, but should be available through the same interface of Arrow.write. Refer to Arrow.jl documentation at their page for further explanation.
