-------------------------------------------------
Hi [~blerer],
I'm Dineth from Sri Lanka. I would like to work on this task as a part of GSOC.
I have already cloned the Cassandra project and went through the given
explanation document. Where would be the best place to start referring to the
codebase to get an idea about the task?
thank you
> Add support for EXPLAIN statements
> ----------------------------------

> Key: CASSANDRA-17380
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17380
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Benjamin Lerer
> Priority: Normal
> Labels: gsoc, gsoc2022
>
> We should provide users a way to understand how their query will be executed
> and some information on the amount of work that will be performed.
> Explain statements are the most common way to do that.
> A CEP Draft has been open for that: [(DRAFT) CEP-4:
> Explain|https://docs.google.com/document/d/1s_gc4TDYdDbHnYHHVxxjqVVUn3MONUqG6W2JehnC11g/edit].
> This draft propose to add support for {{EXPLAIN}} and {{EXPLAIN ANALYZE}}
> but I believe that we should split the work in 2 parts because a simple
> {{EXPLAIN}} would already provide relevant information.
> To complete this work I believe that the following steps will be required:
> * Rework and submit the CEP
> * Add missing statistics
> * Implements the logic behind the EXPLAIN statements
