Gravitee Elassandra Repository

Elassandra repository (Management, Rate Limit and Analytics), with the following benefits:

• Distributed gravitee configuration on many datacenters through the Cassandra replication (in active/active mode).
• Elasticsearch reporting for gravitee analytics.
• Scalability by adding Elassandra nodes (without re-indexing) and datacenters (for geo localisation concerns or workload separation)
• Reduce the global complexity and TCO by using the same NoSQL database for both gravitee configuration, reporting and APIs data storage.

This repository uses Datastax Java driver for communication with Cassandra and Elasticsearch query over CQL.

Requirement

The minimum requirement is :

• Maven3
• Jdk8

In order to use Gravitee snapshot, You need to declare the following repository in you Maven settings :

https://oss.sonatype.org/content/repositories/snapshots

Building

This Elassandra repository use Elassandra-Unit to run gravitee unit tests.

$ git clone https://github.com/strapdata/gravitee-repository-elassandra.git
$ cd gravitee-repository-elassandra
$ mvn clean package

To build the gravitee docker images including this gravitee-repository-elassandra.zip,

build.sh

Strapdata docker images are also available on the Docker Hub:

• strapdata/graviteeio-management-api
• strapdata/graviteeio-gateway

Installing

• Unzip the gravitee-repository-elassandra-[version].zip in the gravitee home directory.
• Copy the gravitee-repository-elassandra-[version].zip in the Gravitee /plugins directory.

Configuration

Configuration settings, prefixed by scope.elassandra, where scope is management or ratelimit:

Parameter	Description	default
localDc	Sets the name of the datacenter that will be considered "local"
contactPoint	Allows to connect to Cassandra cluster nodes. It is not necessary to add all contact points because Cassandra driver will use auto-discovery mechanism.	localhost
endpoint	Defines the Elasticsearch endpoint used to create Elasticsearch indices.	http://localhost:9200
port	Defines the CQL native transport port	9042
keyspaceName	Name of the keyspace. Note that the final will be prefixed with the corresponding scope.	gravitee
username	Permit to connect to Cassandra and Elasticsearch if using access with credentials.	cassandra
password	Permit to connect to Cassandra and Elasticsearch if using access with credentials.	cassandra
index.prefix	Index name prefix (to setup elasticsearch template for indices starting with this prefix)
connectTimeoutMillis	Defines how long the driver waits to establish a new connection to a Cassandra node before giving up	5000
readTimeoutMillis	Controls how long the driver waits for a response from a given Cassandra node before considering it unresponsive	12000
reconnectDelay	Reconnection retry delay in milliseconds	5000
consistencyLevel	Sets the level of consistency for read & write access, e.g. ONE, QUORUM, ALL (see Datastax documentation for comprehensive list)	LOCAL_QUORUM
ssl.truststore.path	Truststore file name (JKS or P12)
ssl.truststore.password	Truststore password
ssl.keystore.path	Keystore file name (JKS or P12) for TLS client authentication
ssl.keystore.password	Keystore password

For analytics, settings are the same as Elasticsearch, see the gravitee documentation (Elassandra is seen as a vanilla Elasticsearch).
