For example, if we were reading a 32MB > block with 1MB buffering, then we will not consume more than 32MB from the > raw InputStream. > This seems like a fairly trivial addition to > {{arrow::io::BufferedInputStream}} to track total read bytes and do not read > beyond the configured extent. We'll have to add a method like > {{set_read_extent}} -- This message was sent by Atlassian Jira (v8.20.10#820010)
