Basic usage

Set the JDBC URL:

-url "jdbc:hive2://<url_jdbc_to_indexima>/"

BASH

To execute a pool:

-script "myScript.sql"

BASH

To execute many pools:

-script "myQueries_1.sql,myQueries_2.sql"

BASH

Example

We are going to create a table, insert data, and execute a few select statements.
Let's create these scripts.

# create_table.sql
CREATE TABLE myTable ( country STRING, population INT, INDEX(country));

# insert_into.sql
INSERT INTO TABLE myTable VALUES ('France', 66000000);
INSERT INTO TABLE myTable VALUES ('Italy', 60000000);
INSERT INTO TABLE myTable VALUES ('England', 55000000);
INSERT INTO TABLE myTable VALUES ('United-States', 327000000);
INSERT INTO TABLE myTable VALUES ('Spain', 48000000);

# select_from.sql
SELECT country, population FROM myTable;
SELECT COUNT(country) FROM myTable;
SELECT AVG(population) FROM myTable;

SQL

Here, we'll execute the three queries scripts sequentially.
Queries inside each script will be executed in concurrence.

java -jar roquettor-1-1.jar
-url "jdbc:hive2://localhost:10000/default"
-user "admin"
-password "myPassword"
-script "create_table.sql,insert_into.sql,select_from.sql"
-threads 3

BASH
