------------------------------------
Summary: In file adapter, scan directory for .csv, .json and .gz
files
Key: CALCITE-1676
URL: https://issues.apache.org/jira/browse/CALCITE-1676
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Fix For: 1.12.0
File adapter should scan the directory for .csv and .json files and convert
each into a table. If the files have a .gz suffix they are assumed to be
gzip-compressed files.
The first line of a .csv file is the column headers. If the file is empty, the
file adapter gives the table a single column, {{EmptyFileHasNoColumns BOOLEAN}}.
