Is there plan to support BigEndian Systems like SUN SPARC Hardware ?

As Apache SPARK supports Big Endian systems. Thanks,Sanjay

Is LittleEndian system mandatory for using Apache Arrow ?

Hi, I read that Integer representation is assumed to LittleEndian in Arrow, does this mean we cannot use Arrow in Big Endian Systems like SPARC ? Thanks,Sanjay

Arrow client C++ Samples with Arrow APIs for Research work

Hi, I am looking for some C++ Samples which I can get started with, with Arrow APIs. Any samples like Top N AlgorithmComplex Key-Value Pair search. Thanks,Sanjay

Vector Bit Pattern Search

Hi, I am trying to write a sample code where I could write the values into Buffer probable read the value from CSV file and store them in-memory and later do bit-pattern search, I am doing performance benchmark as my own study. It would help me if someone could get me the sample code where I

IPC with Systems Using Java version of Apache Arrow

Hi, I am planning to do some experiments with cross-system communication between Hbase and Spark, so I wanted to understand if at all IPC between HBase and Spark possible ? Both are in Java. This question because as I don't see anyway of memory sharing IPC in Java library. Thanks, Sanjay
