Chunked arrays in Feather files

Hi, I have a question about chunks in Feather files. A TableReader can be used to read a Column. For a column, the data is in a ChunkedArray. For a Feather file, what is the chunk size? Can the chunk size be modified? Thanks! Rares

Re: Java Examples Writing Flatbuffer in IPC Message

Thanks Wes. I'm going over the Java source code and I have a few questions: Do we need to define a VectorSchemaRoot every time we define an ArrowStreamWriter? In the interest of developing a simple proof of concept, for now I would just like to ferry a simple byte[] array onto the OutputStream

A simple benchmark on Java implementation

Hi there, I have created a little JMH test to check the Arrow performance. You can found it here. The idea is to test an API with implementations on heap arrays, nio buffers (that follow the arrow format) and Arrow. At this moment the API only supports nullable int buffers and contains read only m
