GMQL Examples

Deployment

GMQL Engine has several deployment modes:

Shell deployment without Repository.

Example Code:

Local Execution (single machine)

  A = SELECT() /home/user1/ds/ref/;
  B = SELECT() /home/user1/ds/exp/;
  S = MAP() A B;
  MATERIALIZE S INTO /home/user1/ds/out/S/;

Yarn Execution (cluster)

  A = SELECT() hdfs://127.0.0.1:9000/user/repo/user1/regions/ref/;
  B = SELECT() hdfs://127.0.0.1:9000/user/repo/user1/regions/exp/;
  S = MAP() A B;
  MATERIALIZE S INTO hdfs://127.0.0.1:9000/user/repo/user1/regions/out/;

Shell Deployment with Repository.

Example Code:

   A = SELECT() ann;
   B = SELECT() exp;
   S = MAP() A B;
   MATERIALIZE S INTO res;
