JDF is the Julia DataFrames serialization format. It’s a specialised serialization format and hence doesn’t support arbitrary objects like JLD2 and JLSO. This loss of generality is more than made up for in gains in speed and reliability for saving and loading DataFrames.
JDF now supports
DataFrames containing these types
T can be
isbits types i.e.
Date* types etc.
RLEVectors support will be considered in the future when
Also, there is now the ability to load only the columns you select. For example
a2_selected = loadjdf("iris.jdf", cols = [:species, :sepalLength, :petalWidth])
From JDF.jl v0.2, I am committed to making all JDF files loadable in ALL future version of JDF.jl.
