Examples: Writing and reading Secondo streams to and from Kafka
|
||
|
|
|
||
|
|
For all tests, first open some database, e.g.:
|
||
|
|
open database berlintest;
|
||
|
|
|
||
|
|
Write data to topic "test" on localhost:
|
||
|
|
query plz feed writetokafka["localhost","test"] count;
|
||
|
|
|
||
|
|
Write data to topic "test" on newton server:
|
||
|
|
query plz feed writetokafka["newton1.fernuni-hagen.de:9093","test"] count
|
||
|
|
|
||
|
|
Read data from topic "test" on localhost:
|
||
|
|
query readfromkafka("localhost", "test", FALSE) count;
|
||
|
|
|
||
|
|
Read data from topic "test" on newton server:
|
||
|
|
query readfromkafka("newton1.fernuni-hagen.de:9093", "test", FALSE) count;
|
||
|
|
|
||
|
|
Read existing data from topic "test" on localhost and waiting&reading for new data :
|
||
|
|
query readfromkafka("localhost", "test", TRUE) finishStream[8080] consoleConsumer consume;
|
||
|
|
|
||
|
|
From other instances new data can be added to topic, e.g.
|
||
|
|
query plz feed filter [.Ort="Karlsruhe"] writetokafka["localhost","test"] consume;
|
||
|
|
query plz feed filter [.PLZ=76189] writetokafka["localhost","test"] consume;
|
||
|
|
|
||
|
|
The waiting can be finished by calling from other terminal:
|
||
|
|
query signalFinish("localhost", 8080);
|
