This scenario applies only to Talend products with Big Data.

For more technologies supported by Talend, see Talendコンポーネント.

This scenario describes a simple Job that reads the employee data from a CSV file, writes the data to a Cassandra keyspace, then extracts the personal information of some employees and displays the information on the console.

This scenario requires six components, which are:
  • tCassandraConnection: opens a connection to the Cassandra server.

  • tFileInputDelimited: reads the input file, defines the data structure and sends it to the next component.

  • tCassandraOutput: writes the data it receives from the preceding component into a Cassandra keyspace.

  • tCassandraInput: reads the data from the Cassandra keyspace.

  • tLogRow: displays the data it receives from the preceding component on the console.

  • tCassandraClose: closes the connection to the Cassandra server.
