Stargate Scanner Filter Examples

Introduction

So yeah... no documentation for the HBase REST API in regards to what should a filter look like...

So I installed Eclipse, got the library, and took some time to find some of the (seemingly) most useful filters you could use. I'm very green at anything regarding HBase, and I hope this will help anyone trying to get started with it.

What I discovered is that basically, attributes of the filter object follow the same naming than in the documentation. For this reason, I have made the link clickable and direct them to the HBase Class documentation attached to it; check for the instantiation argument names, and you will have your attribute list (more or less).

! Note that logs go in /usr/local/var/log/ejabberd/ (if you cant find logs here either, just run ./ejabberdct without any arguments and the default log location will be shown as examples)


To create an admin user, go to sbin:

./ejabberdctl register admin www.yourdomain.com (I believe the server config file should contain this host)

Introduction to Kafka

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:

• Producers send messages to brokers
• Consumers read messages from brokers
• Messages are sent to a topic

// saving documents
store.save({name:'brian'});

// optionally pass a key
store.save({key:'config', settings:{color:'blue'}});

// updating a document in place is the same syntax
