Neal Richardson created ARROW-5502: -------------------------------------- Summary: [R] file readers should mmap Key: ARROW-5502 URL: https://issues.apache.org/jira/browse/ARROW-5502 Project: Apache Arrow Issue Type: Improvement Components: R Reporter: Neal Richardson Fix For: 0.14.0
Arrow is supposed to let you work with datasets bigger than memory. Memory mapping is a big part of that. It should be the default way that files are read in the `read_*` functions. To disable memory mapping, we could use a global `option()`, or a function argument, but that might clutter the interface. Or we could not give a choice and only fall back to not memory mapping if the platform/file system doesn't support it. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
