How to append values to a dataset?

[YoshieraHuang]

I use HDF5 to persist my large time-series data. I want to write my data asynchronously while receiving. Could you tell me how to create a dataset which maxlength is infinite and to append data to the end of this dataset?

You can use the resizable function when declaring your variable.

As @magnusuMET said, you can declare it as resizable (you can also write slices and not overwrite the whole dataset if needed).
