Wamsi Viswanath created ARROW-7512: -------------------------------------- Summary: Dictionary memo missing elements in id_to_dictionary_ map after deserialization Key: ARROW-7512 URL: https://issues.apache.org/jira/browse/ARROW-7512 Project: Apache Arrow Issue Type: Bug Components: C++ Affects Versions: 0.15.0 Reporter: Wamsi Viswanath
`id_to_dictionary_` map is empty after de-serialization of schema using ReadSchema method. An example for reproduction: [https://gist.github.com/wamsiv/77dc1db44b5805828172e6c94d61d2d9] I see that it is probably being missed here: https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/metadata_internal.cc#L804 Please let me know if the behavior is expected and if so then how the client is expected to have dictionary array values? -- This message was sent by Atlassian Jira (v8.3.4#803005)
