I think you have a misunderstanding of the expected use pattern of Arrow vectors. Variable-width vectors need to be populated in order. They are randomly-readable once populated but they are not randomly-writable. For reference, at Dremio we did build a Arrow-vector like structure for doing what you want. You can see the code here: https://github.com/dremio/dremio-oss/blob/master/sabot/kernel/src/main/java/org/apache/arrow/vector/MutableVarcharVector.java ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
