------------------------------------
Summary: Add Cassandra Interpreter
Key: ZEPPELIN-179
URL: https://issues.apache.org/jira/browse/ZEPPELIN-179
Project: Zeppelin
Issue Type: Improvement
Components: Interpreters
Affects Versions: 0.6.0
Reporter: DOAN DuyHai
This is a Cassandra interpreter for Zeppelin.
I tried to make the code as clean & modular as possible. The code coverage is
quite high with 75 tests (unit tests + integration tests).
Below are the features of the interpreters:
- support single-line and multi-line comments
- one CQL statement can span many line
- a magic *@prefix* system to pass in runtime parameters to queries
- support for preparing statements before-hand and injecting bound values to
prepared statements
- parallel execution of each paragraphs
- the last statement is displayed as tabular data if it is a SELECT statement.
For non SELECT statements, execution statistics are returned
- simple syntax validation by the interpreter, CQL syntax validation is
delegated to Cassandra
- support for Zeppelin dynamic form with the mustache syntax
{{input_name=default value}} or {{select_name=val1 | val2 | ... | valN}}
For all the details about the features of this interpreter, please read the doc
