Examples with Admin com.mapr.db.Admin used on opensource projects

Example 1 with Admin

use of com.mapr.db.Admin in project drill by apache.

the class IndexPlanTest method setupTableIndexes.

/**
 *  A sample row of this 10K table:
 *   ------------------+-----------------------------+--------+
 *   | 1012  | {"city":"pfrrs","state":"pc"}  | {"email":"KfFzKUZwNk@gmail.com","phone":"6500005471"}  |
 *   {"ssn":"100007423"}  | {"fname":"KfFzK","lname":"UZwNk"}  | {"age":53.0,"income":45.0}  | 1012   |
 *
 * This test suite generate random content to fill all the rows, since the random function always start from
 * the same seed for different runs, when the row count is not changed, the data in table will always be the same,
 * thus the query result could be predicted and verified.
