Gift Sinthong updated ASTERIXDB-2901:
-------------------------------------
Description:
Creating external datasets from CSV files should be able to infer the attribute
names from the file header if present and sample records for the data type. For
example, in the create statement there could be an "infer" flag that takes in
the number of records to scan like the below statement.
CREATE EXTERNAL DATASET Employee() USING localfs
(("path"="localhost:///employees.csv"), ("format"="delimited-text"),
("delimiter"=","), ("header"=true), ("infer"=10))
