Index Advisor Service for Couchbase N1QL (SQL for JSON)

,

Couchbase N1QL is a SQL-like language for JSON data. To retrieve and manipulate JSON data effectively, we need appropriate indexes. The rules for creating these indexes can be read here. But that involves too much reading, hence we now have an Index Advisor service that accepts a query and gives out an index recommendation that would meet the expectations of the Couchbase query engine — all without downloading the latest Couchbase server.

This service will provide index recommendations to help DBAs, developers, and architects optimize query performance and meet the SLAs.

A Simple HTTP Server in Java

,

Do you want to implement an HTTP server, but do you not want to take any risk of writing a full-fledged HTTP server? Developing an HTTP server with full capability is not a trivial task. But Java has got a solution to this kind of problem. Java supports an in-built HTTP server. By just writing 100 lines of code, we can develop a somewhat-decent HTTP server that can handle HTT$$anonymous$$ET and POST requests. We can also leverage it to handle other HTTP commands as well.
