Avro serialization

There are 4 possible serialization format when using avro:

Avro Json encoding
Avro Data Serialization (https://avro.apache.org/docs/current/spec.html#Data+Serialization) Binary format with an header that contains the full schema, this is the format usually used when writing Avro files
Avro Single Object Encoding (https://avro.apache.org/docs/current/spec.html#single_object_encoding) Binary format with an header with only the fingerprint/id of the schema, this it the format used by Kafka (see this
Avro Binary Encoding (https://avro.apache.org/docs/current/spec.html#binary_encoding)

Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

Reset the consumer offset for a topic (preview)
