We could improve the performance of these accesses by creating a > single instance of the proxy and store it on the vector or the data type and > then reuse that instance. > This should improve performance. > See > https://github.com/apache/arrow/blob/7029f90ea3b39e97f1a671227ca932cbcdbcee05/js/src/visitor/get.ts#L219 > and > https://github.com/apache/arrow/blob/7029f90ea3b39e97f1a671227ca932cbcdbcee05/js/src/vector/struct.ts#L27. > -- This message was sent by Atlassian Jira (v8.20.1#820001)
