Hi, I worked on a showcase to embed a Apache Cassandra DB inside Apache Karaf [1]. This could be used for either prototyping with Cassandra or as an alternative backend for the Decanter project. Additionally I played with some shell commands for easy debugging purposes, for details take a look [2]. For example you're able to connect to any given Cassandra cluster issue some CQL statements either from the command line or from a file. Additionally I added some CQLSH like commands including completion for easy usage of USE, CREATE, SELECT or INSERT statements. For this I needed to alter the Karaf shell a bit (with the help of gnodet :-) ) To disable the shell interpretation of quotes and brackets. Now that I altered the handling in Karaf/GOGO shell in a custom Karaf [3], the question is, can we port this back to Karaf in a way that we don't need to alter the gogo shell stuff again and have our own classes [4]. Another Idea that came to my mind was to have a stripped down shell that could be used for any SQL-like command. A similar completion syntax could be used for any SQL Select, not only for the CQL syntax of Cassandra.
