#' Tools to Transform and Query Data with 'Apache' 'Drill'
#'
#' Drill is an innovative low-latency distributed query engine designed to enable data
#' exploration and analytics on both relational and non-relational datastores, scaling to
#' petabytes of data. Users can query the data using standard SQL and BI tools without
#' having to create and manage schemas. Some of the key features are:
#'
#' \itemize{
#'   \item{Schema-free JSON document model similar to MongoDB and Elasticsearch}
#'   \item{Industry-standard APIs: ANSI SQL, ODBC/JDBC, RESTful APIs}
#'   \item{Extremely user and developer friendly}
#'   \item{Pluggable architecture enables connectivity to multiple datastores}
#' }
#'
#' Drill includes a distributed execution environment, purpose built for large-scale data
#' processing. At the core of Drill is the "Drillbit" service which is responsible for
#' accepting requests from the client, processing the queries, and returning results to
#' the client.
#'
#' You can install and run a Drillbit service on one node or on many nodes to form a
#' distributed cluster environment. When a Drillbit runs on each data node in a cluster,
#' Drill can maximize data locality during query execution without moving data over the
#' network or between nodes. Drill uses ZooKeeper to maintain cluster membership and health
#' check information.
#'
#' Methods are provided to work with Drill via the native JDBC & REST APIs along with R
#' \code{DBI} and \code{dplyr} interfaces.
