Example: Output in Default Mode

In our example, name of the data connection is Recommendation and queries are accessed from the text.txt file.

The output has the following two sections:

  • Recommended Analytical Views section shows the recommended aviews with the CREATE ANALYTICAL VIEW statements, and has the following information:

    Table Name

    Name of the base table that appears in the form database_name.table_name. In our example, it is test.recom1.

    Recommended Aviews

    Names of the recommended aviews. In our example, it is recommended_aview_1

    File Format

    Format of the base table. In our example, it is PARQUET.

    Select query

    Syntax of the select query. In our example, it is SELECT avg(f), c, count(a), e FROM test.recom1 GROUP BY c, e;

  • Recommended Details section shows the queries executed and the recommended aviews with the following information:

    Q1

    Detail of each query that is executed. In our example, we only have one query, which is SELECT avg(f), c, count(a), e FROM test.recom1 GROUP BY c, e;.

    RECOMMENDATION

    Names of the recommended aviews. In our example, we only have one recommendation, recommended_aview_1.

./arcviz util recommendation --dcname=Recommendation --file=/var/lib/arcadia/test.txt

Recommended Analytival Views: 
-- recommended_aview_1 : 
   CREATE ANALYTICAL VIEW `test`.`recommended_aview_1` STORED AS PARQUET 
      AS SELECT avg(f), c, count(a), e FROM test.recom1 GROUP BY c, e;
-------------------------------------------------------------------------
Recommendation Details: 
-- Q1: select count(a), avg(f), c, e from test.recom1 group by 3,4; 
      -- RECOMMENDATION: recommended_aview_1
