---------------------------------
Summary: Errors in Struct type's example and missing reference in
Layout.md
Key: ARROW-1166
URL: https://issues.apache.org/jira/browse/ARROW-1166
Project: Apache Arrow
Issue Type: Bug
Components: Documentation
Affects Versions: 0.4.1
Reporter: Fang Zheng
Priority: Trivial
Fix For: 0.5.0
Hi,
There seem to be several minor issues in Layout.md:
1. In the example for Struct type
(https://github.com/apache/arrow/blob/master/format/Layout.md#struct-type), the
second array element is "{null, 2}" in the text, but in the Arrow
representation, the value buffer for field 0 has "bob" in the corresponding
slot. Either the text should be changed from "null" to "bob", or the Null
count, Null bitmap buffer, and Offsets buffer should be changed to count the
second element in field 0 as null.
2. In the same Struct type example, the third element in the Struct array is
"null" in text, but the value buffer for field 1 has 3 in the corresponding
slot in the Arrow representation. The Null count, Null bitmap buffer, and Value
buffer should be changed to count the third element in field 1 as null.
3. In the Dictionary encoding section
(https://github.com/apache/arrow/blob/master/format/Layout.md#dictionary-encoding),
there is a missing reference to "Message.fbs".
