Scenario: Handling data with Cassandra
This scenario applies only to a Talend solution with Big Data.
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.
-
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.
