jjbskir opened a new issue, #1148: URL: https://github.com/apache/arrow-java/issues/1148
### Describe the enhancement requested The Java `VectorSchemaRoot.getVector(String name)` can be quite slow if a schema has many vectors. The code currently loops over all the field vectors until it finds the string match. [Link to code](https://github.com/apache/arrow-java/blob/3bc34b041761081ac32a7cd3b167f9ab8b628677/vector/src/main/java/org/apache/arrow/vector/VectorSchemaRoot.java#L175). Could we stroe a hash map of the `FieldVector` String name to the actual `FieldVector`? Basically the same thing as the `fieldVectorsMap` that maps the `Field` to `FieldVector`. For really wide datasets the trade off of a bit more memory for faster vector lookups would be really nice to have! Happy to open up a PR with the improvement, thanks! -- This is an automated message from the Apache Git Service.
