Generating Materialized Views

continuent-tools-hadoop are packaged within the main Tungsten Replicator software bundle and can be found within ./tungsten-replicator/support/hadoop-tools

The load-reduce-check command performs four distinct steps:

  1. Reads the schema from the MySQL server and creates the staging table DDL within Hive
  2. Reads the schema from the MySQL server and creates the base table DDL within Hive
  3. Executes the materialized view process on each selected staging table data to build the base table content.
  4. Performs a data comparison
