Telepat Models Library

This package is used by the Telepat API and the Telepat Worker.

This package contains the libraries for using various telepat resources:

• Databases:

  • At the moment only elasticSearch support is implemented (version 1.7.x). Configuration variables:
    • TP_ES_HOST: Elasticsearch server:port. This option will use autodiscovery.
    • TP_ES_HOSTS: server1:port,server2:port. This option will not use autodiscovery.
    • TP_ES_INDEX: Elasticsearch index
    • TP_ES_SUBSCRIBE_LIMIT (optional): How many results the modelSearch method (used in subscriptions) should return (paginated). Default 64.
    • TP_ES_GET_LIMIT (optional): How many resutls every other search methods should return (not paginated, fixed). Default 384.
  • The state database doesn't use the adapter model yet because it's locked to Redis. Only Subscription.js uses it.
    • TP_REDIS_HOST: Redis server
    • TP_REDIS_PORT: Redis server port

• Messaging Systems:

  • Apache Kafka
    • TP_KFK_HOST: Kafka (zooekeeper) server
    • TP_KFK_PORT: Kafka (zooekeeper) server port
  • Azure ServiceBus
    • TP_AZURESB_CONNECTION_STRING: Azure SB connection string
    • TP_AZURESB_MSG_POLLING: How fast should the messaging server be polled (in milliseconds)
  • AMQP: we've tested it with RabbitMQ 3.5.5
    • TP_AMQP_HOST: AMQP server host
    • TP_AMQP_USER: AMQP user used by Telepat
    • TP_AMQP_PASSWORD: The password for the user

• Loggers:

  • We use winston logger: Winston
  • TP_LOGGER: the name of the Winston logger (eg.: Console)
  • TP_LOG_LEVEL: logging level
