Create a Table

Run clickhouse-client and execute the following CREATE query:

CREATE TABLE recipes
(
title String,
ingredients Array(String),
directions Array(String),
link String,
source LowCardinality(String),
NER Array(String)
) ENGINE = MergeTree ORDER BY title;

Insert the Data

Run the following command:

clickhouse-client --query "
INSERT INTO recipes
SELECT
title,
JSONExtract(ingredients, 'Array(String)'),
JSONExtract(directions, 'Array(String)'),
link,
source,
JSONExtract(NER, 'Array(String)')
FROM input('num UInt32, title String, ingredients String, directions String, link String, source LowCardinality(String), NER String')
FORMAT CSVWithNames
" --input_format_with_names_use_header 0 --format_csv_allow_single_quote 0 --input_format_allow_errors_num 10 < full_dataset.csv

This is a showcase how to parse custom CSV, as it requires multiple tunes.

Explanation:

  • The dataset is in CSV format, but it requires some preprocessing on insertion; we use table function input to perform preprocessing;
  • The structure of CSV file is specified in the argument of the table function input;
  • The field num (row number) is unneeded - we parse it from file and ignore;
  • We use FORMAT CSVWithNames but the header in CSV will be ignored (by command line parameter --input_format_with_names_use_header 0), because the header does not contain the name for the first field;
  • File is using only double quotes to enclose CSV strings; some strings are not enclosed in double quotes, and single quote must not be parsed as the string enclosing - that's why we also add the --format_csv_allow_single_quote 0 parameter;
  • Some strings from CSV cannot parse, because they contain \M/ sequence at the beginning of the value; the only value starting with backslash in CSV can be \N that is parsed as SQL NULL. We add --input_format_allow_errors_num 10 parameter and up to ten malformed records can be skipped;
  • There are arrays for ingredients, directions and NER fields; these arrays are represented in unusual form: they are serialized into string as JSON and then placed in CSV - we parse them as String and then use JSONExtract function to transform it to Array.
