Issue facing, Aerospike Connect for Kafka - Inbound
I generate a simple pricing as follows:
echo "${UUID}:${TICKER}" >> ${IN_FILE}
UUID is the key and ticker is the name of security like “IBM”
This is what I have in my shell script
cat ${IN_FILE} | ${KAFKA_HOME}/bin/kafka-console-producer.sh \
--broker-list
rhes75:9092,rhes75:9093,rhes75:9094,rhes564:9092,rhes564:9093,rhes564:9094,rhes76:9092,rhes76:9093,rhes76:9094
\
--topic md \
--property "parse.key=true" \
--property "key.separator=:"
And this is what I get
${KAFKA_HOME}/bin/kafka-console-consumer.sh --zookeeper
rhes75:2181,rhes564:2181,rhes76:2181 --topic md --property print.key=true
6af48cd4-c4ce-44a0-adb7-8d980b2b79a0 IBM
8436ac7f-d2ae-4762-bf4e-98242241290b IBM
96bbb149-b11c-440d-a82c-f78e53edda49 IBM
5fa8682b-d81a-466a-abbd-ca80793405b1 IBM
a998446a-497f-4ac7-a5a7-21a524cfc4da IBM
7920affe-6641-48ef-9e08-5a4b9f66da4d IBM
Now I want to post this data into aerospike
My files are as follows:
*cat connect-standalone.properties*
# These are defaults. This file just demonstrates how to override some
settings.
bootstrap.servers=rhes75:9092, rhes564:9092,rhes76:9092
# The converters specify the format of data in Kafka and how to translate it
# into Connect data. Every Connect user will need to configure these based
on
# the format they want their data in when loaded from or stored into Kafka
#
key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.storage.StringConverter
##alue.converter=org.apache.kafka.connect.json.JsonConverter
#
# Converter-specific settings can be passed in by prefixing the Converter's
# setting with the converter we want to apply it to
key.converter.schemas.enable=true
value.converter.schemas.enable=false
# The internal converter used for offsets and config data is configurable
and
# must be specified, but most users will always want to use the built-in
# default. Offset and config data is never visible outside of Kafka Connect
in
# this format.
##internal.key.converter=org.apache.kafka.connect.json.JsonConverter
##internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter=org.apache.kafka.connect.storage.StringConverter
internal.value.converter=org.apache.kafka.connect.storage.StringConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
offset.storage.file.filename=/tmp/connect.offsets
# Flush much faster than normal, which is useful for testing/debugging
offset.flush.interval.ms=10000
# Set to a list of filesystem paths separated by commas (,) to enable class
# loading isolation for plugins (connectors, converters, transformations).
The
# list should consist of top level directories that include any combination
of:
# a) directories immediately containing jars with plugins and their
dependencies
# b) uber-jars with plugins and their dependencies
# c) directories immediately containing the package directory structure of
# classes of plugins and their dependencies Note: symlinks will be followed
to
# discover dependencies or plugins.
# Examples:
plugin.path=/opt/aerospike-kafka-connect-sink/share/kafka
And my sink-properies file is
*cat aerospike-sink.properties*

Hi,
I sorted this one out.
It was to do with the format of published prices.
