Testing conductivity in JRedisSearch to Redis without a previous created Index

The Client Class, which wraps all connection and command calls to the RediSearch module, requires an index when creating an instance.

Any Client method invocation that cannot be connected to Redis with the connection information provided when calling the constructor you will get the following exception JedisConnectionException from Jedis this exposes the jedis api to all users of the JRediseach api.

If the connection information works and there is a successfull connection but the index used is not present then any valid call to the methods in the Client class will result in various exceptions depending on the call accept the one to createIndex which will create the index.

Examples:

 

  • dropIndex(boolean) will return false but really the api is suppressing the thrown exception that the index was not found.
  • getInfo() which will throw an “JedisDataException: Unknown Index name”.

 

None of these approaches are ideal but for now my vote would be to call getInfo since no harm can happen, dropIndex and others can actually alter the index if it did all ready exsist.

Microstack Developer

Definition of Microstack: A set of Microservices developed to provide a coherent set of API's, UI/UX, Security and bridging legacy systems.

The popularity of Microservices has grown and many large companies have started to adopt Microservices. There are many books, blogs and opinions... on Microservices and their implementation. I have been using the term Microstack, to address the fact that the past traditional Fullstack way of development does not cut it. A colleague of mine never heard this before and has encouraged me to describe it. Hence the definition in this blog post to capture what I believe is the coining of the term Microstack.

In my own experiences in deploying the complete solution of Microservices there is a growing need for the Development, Architecture and Devop teams to work together to produce a complete deployable solution for Production. This new type of Microstack Team will address the needs of the stack to make a Production Product successful.
