The following recipes are sampled from a trained neural net. You can find the repo to train your own neural net here: https://github.com/karpathy/char-rnn Thanks to Andrej Karpathy for the great code! It's really easy to setup.
The recipes I used for training the char-rnn are from a recipe collection called ffts.com And here is the actual zipped data (uncompressed ~35 MB) I used for training. The ZIP is also archived @ archive.org in case the original links becomes invalid in the future.
Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.
Terminology:
bin/kafka-topics.sh --zookeeper localhost:2181 --list
bin/kafka-topics.sh --zookeeper localhost:2181 --describe --topic mytopic
bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic mytopic --config retention.ms=1000

Simply put, a keyspace "MISS" means some piece of data you tried to retrieve from Redis was not there. This usually means that one of the following things happened:
Vertical decomposition. Creating cohesive services
One of the biggest misconceptions about services is that a service is an independent deployable unit, i.e., service equals process. With this view, we are defining services according to how components are physically deployed. In our example, since it’s clear that the backend admin runs in its own process/container, we consider it to be a service.
But this definition of a service is wrong. Rather you need to define your services in terms of business capabilities. The deployment aspect of the system doesn’t have to be correlated to how the system has been divided into logical services. For example, a single service might run in different components/processes, and a single component might contain parts of multiple services. Once you start thinking of services in terms of business capabilities rather than deployment units, a whole world of options open.
What are the Admin UI
brew install git bash-completion
Configure things:
git config --global user.name "Your Name"
git config --global user.email "you@example.com"
Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups
command.
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.
