What is the method for querying data in Voltdb?

The method for querying data with VoltDB is by using SQL query statements, which can retrieve data from one or more tables using the SELECT statement. For example:

SELECT * FROM table_name;

This query will return all rows and columns in the table. You can also use a WHERE clause to add filtering conditions to limit the results returned. For example:

SELECT * FROM table_name WHERE column_name = 'value';

This query will retrieve all rows with a column named column_name and a value of ‘value’. You can also use other SQL functions and features to further manipulate the returned data.
