Description: 'Apache Drill' is a low-latency distributed query engine designed to enable |
|||
data exploration and 'analytics' on both relational and non-relational 'datastores', |
|||
scaling to petabytes of data. Methods are provided that enable working with 'Apache' |
|||
'Drill' instances via the 'JDBC' 'DBI' and 'dplyr'/'dbplyr' idioms. |

0.1.0 |
|||
* Initial release |
|||
# sergeant 0.6.0 |
|||
|
|||
- Authentication support for DBI/dplyr and `drill_connection()` pure REST interface |
|||
|
|||
# sergeant 0.5.2 |
|||
|
|||
- Make rJava & RJDBC optional (WIP) |
|||
- Hack to remove ";" at end of queries sent to `drill_query()` |
|||
- Added `dbplyr` windows functions to `sql_translate_env` |
|||
|
|||
# sergeant 0.4.0 |
|||
|
|||
- Getting ready for new `dplyr` (thx to Edward Visel) |
|||
- Cleaned up roxygen docs so that `src_drill` is exported now. |
|||
|
|||
# sergeant 0.3.2 |
|||
|
|||
- Finally got quoting done. I thought I had before but I guess I hadn't. |
|||
- Added documnentation for built-in and custom Drill function that are supported. |
|||
|
|||
# sergeant 0.3.1.9000 |
|||
|
|||
* fixed `src_drill()` example |
|||
* JDBC driver still in github repo but no longer included in pkg builds. See |
|||
README.md or `drill_jdbc()` help for more information on using the JDBC |
|||
driver with sergeant. |
|||
|
|||
# sergeant 0.3.0.9000 |
|||
|
|||
* New DBI interface (to the REST API) |
|||
* dplyr interface now uses the DBI interace to the REST API |
|||
* CRAN checks pass besides size (removing JDBC driver in next dev iteration) |
|||
|
|||
# sergeant 0.2.1.9000 |
|||
|
|||
* implemented a large subset of Drill SQL Functions <https://drill.apache.org/docs/about-sql-function-examples/> |
|||
|
|||
# sergeant 0.2.0.9000 |
|||
|
|||
* experimental alpha dplyr driver |
|||
|
|||
# sergeant 0.1.2.9000 |
|||
|
|||
* can pass RJDBC connections made with `drill_jdbc()` to `drill_query()` |
|||
* finally enaled `nodes` parameter to be a multi-element character vector as it said |
|||
in the function description |
|||
|
|||
# sergeant 0.1.2.9000 |
|||
|
|||
* support embedded drill JDBC connection |
|||
|
|||
# sergeant 0.1.1.9000 |
|||
|
|||
* tweaked `drill_query()` and `drill_version()` |
|||
|
|||
# sergeant 0.1.0.9000 |
|||
|
|||
* Added JDBC connector and included JDBC driver in the package (for now) |
|||
* Changed idiom to piping in a connection object |
|||
* Added a `NEWS.md` file to track changes to the package. |

#' 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. |

Tools to Transform and Query Data with 'Apache' 'Drill' (JDBC) |
|||
|
|||
## NOTE |
|||
|
|||
This is the Java/JDBC-interface to Apache Drill. For non-Java/JDBC, see the `sergeant` package ([GitLab](https://gitlab.com/hrbrmstr/sergeant/); [GitHub](https://github.com/hrbrmstr/sergeant/)). |
|||
|
|||
## Description |
|||
|
|||
## What's Inside The Tin |
|||
Drill + `sergeant` is (IMO) a streamlined alternative to Spark + `sparklyr` if you don't need the ML components of Spark (i.e. just need to query "big data" sources, need to interface with parquet, need to combine disparate data source types — json, csv, parquet, rdbms - for aggregation, etc). Drill also has support for spatial queries. |
|||
|
|||
Using Drill SQL queries that reference parquet files on a local linux or macOS workstation can often be more performant than doing the same data ingestion & wrangling work with R (especially for large or disperate data sets). Drill can often help further streaming workflows that infolve wrangling many tiny JSON files on a daily basis. |
|||
|
|||
Drill can be obtained from <https://drill.apache.org/download/> (use "Direct File Download"). Drill can also be installed via [Docker](https://drill.apache.org/docs/running-drill-on-docker/). For local installs on Unix-like systems, a common/suggestion location for the Drill directory is `/usr/local/drill` as the install directory. |
|||
|
|||
Drill embedded (started using the `$DRILL_BASE_DIR/bin/drill-embedded` script) is a super-easy way to get started playing with Drill on a single workstation and most of many workflows can "get by" using Drill this way. |
|||
|
|||
The following functions are implemented: |
|||
|
|||
**`DBI`** (RJDBC) |
|||
|
|||
- `drill_jdbc`: Connect to Drill using JDBC, enabling use of said idioms. See `RJDBC` for more info. |
|||
|
|||
NOTE: The DRILL JDBC driver fully-qualified path must be placed in the `DRILL_JDBC_JAR` environment variable. This is best done via `~/.Renviron` for interactive work. i.e. `DRILL_JDBC_JAR=/usr/local/drill/jars/drill-jdbc-all-1.14.0.jar` |
|||
|
|||
**`dplyr`**: (RJDBC) |
|||
|
|||
- `src_drill_jdbc`: Connect to Drill (using dplyr & RJDBC) + supporting functions |
|||
|
|||

|
|||
Drill can be obtained from <https://drill.apache.org/download/> (use |
|||
“Direct File Download”). Drill can also be installed via |
|||
[Docker](https://drill.apache.org/docs/running-drill-on-docker/). For |
|||
local installs on Unix-like systems, a common/suggestion location for |
|||
the Drill directory is `/usr/local/drill` as the install directory. |
|||
|
|||
Drill embedded (started using the `$DRILL_BASE_DIR/bin/drill-embedded` |
|||
script) is a super-easy way to get started playing with Drill on a |
|||
single workstation and most of many workflows can “get by” using Drill |
|||
this way. |
|||
|
|||
The following functions are implemented: |
|||
|
|||
**`DBI`** (RJDBC) |
|||
|
|||
- `drill_jdbc`: Connect to Drill using JDBC, enabling use of said |
|||
idioms. See `RJDBC` for more info. |
|||
|
|||
NOTE: The DRILL JDBC driver fully-qualified path must be placed in the |
|||
`DRILL_JDBC_JAR` environment variable. This is best done via |
|||
`~/.Renviron` for interactive work. i.e. |
|||
`DRILL_JDBC_JAR=/usr/local/drill/jars/drill-jdbc-all-1.14.0.jar` |
|||
|
|||
**`dplyr`**: (RJDBC) |
|||
|
|||
- `src_drill_jdbc`: Connect to Drill (using dplyr & RJDBC) + |
|||
supporting |
|||
functions |
|||
|
|||

## Reverse dependencies |
|||
|

This is a new release, so there are no reverse dependencies. |

|
|||
* WinBuilder seems to be working now (it found httr and covr in the last build). |
|||
|
|||
* Removed png causing WinBuilder pandoc problems. |
|||
|
|||
* R-hub is reporting httr and covr are not available so |
|||
I have not been able to get it to work successfully on that platform. |
|||
|
|||
* The examples and tests are wrapped in \dontrun{} or testthat:::skip_on_cran() |
|||
since they absolutely require a running Apache Drill server. Full tests |
|||
are run on Travis (weekly) with results avaialble for review: |
|||
https://travis-ci.org/hrbrmstr/sergeant |
|||
|
|||
The Travis tests install Apache Drill and test out the REST API calls |
|||
as well as the dplyr/dbplyr interface with live queries. |
|||
|
|||
* Code coverage is run and is currently at 40% |

<p><code>sergeant</code> : Tools to Transform and Query Data with ‘Apache’ ‘Drill’</p> |
|||
<p>Drill + <code>sergeant</code> is (IMO) a nice alternative to Spark + <code>sparklyr</code> if you don’t need the ML components of Spark (i.e. just need to query “big data” sources, need to interface with parquet, need to combine disparate data source types — json, csv, parquet, rdbms - for aggregation, etc). Drill also has support for spatial queries.</p> |
|||
<p>I find writing SQL queries to parquet files with Drill on a local linux or macOS workstation to be more performant than doing the data ingestion work with R (for large or disperate data sets). I also work with many tiny JSON files on a daily basis and Drill makes it much easier to do so. YMMV.</p> |
|||
<p>You can download Drill from <a href="https://drill.apache.org/download/" class="uri">https://drill.apache.org/download/</a> (use “Direct File Download”). I use <code>/usr/local/drill</code> as the install directory. <code>drill-embedded</code> is a super-easy way to get started playing with Drill on a single workstation and most of my workflows can get by using Drill this way. If there is sufficient desire for an automated downloader and a way to start the <code>drill-embedded</code> server from within R, please file an issue.</p> |
|||
<p>There are a few convenience wrappers for various informational SQL queries (like <code><a href="reference/drill_version.html">drill_version()</a></code>). Please file an PR if you add more.</p> |
|||
<p>The package has been written with retrieval of rectangular data sources in mind. If you need/want a version of <code><a href="reference/drill_query.html">drill_query()</a></code> that will enable returning of non-rectangular data (which is possible with Drill) then please file an issue.</p> |
|||
<p>Some of the more “controlling vs data ops” REST API functions aren’t implemented. Please file a PR if you need those.</p> |
|||
<p>Finally, I run most of this locally and at home, so it’s all been coded with no authentication or encryption in mind. If you want/need support for that, please file an issue. If there is demand for this, it will change the R API a bit (I’ve already thought out what to do but have no need for it right now).</p> |
|||
<p>The following functions are implemented:</p> |
|||
<p><strong><code>DBI</code></strong></p> |
|||
<ul> |
|||
<li>As complete of an R <code>DBI</code> driver has been implemented using the Drill REST API, mostly to facilitate the <code>dplyr</code> interface. Use the <code>RJDBC</code> driver interface if you need more <code>DBI</code> functionality.</li> |
|||
<li>This also means that SQL functions unique to Drill have also been “implemented” (i.e. made accessible to the <code>dplyr</code> interface). If you have custom Drill SQL functions that need to be implemented please file an issue on GitHub.</li> |
|||
</ul> |
|||
<p><strong><code>RJDBC</code></strong></p> |
|||
<ul> |
|||
<li> |
|||
<code>drill_jdbc</code>: Connect to Drill using JDBC, enabling use of said idioms. See <code>RJDBC</code> for more info.</li> |
|||
<li>NOTE: The DRILL JDBC driver fully-qualified path must be placed in the <code>DRILL_JDBC_JAR</code> environment variable. This is best done via <code>~/.Renviron</code> for interactive work. i.e. <code>DRILL_JDBC_JAR=/usr/local/drill/jars/drill-jdbc-all-1.9.0.jar</code> |
|||
</li> |
|||
</ul> |
|||
<p><strong><code>dplyr</code></strong>:</p> |
|||
<ul> |
|||
<li> |
|||
<code>src_drill</code>: Connect to Drill (using dplyr) + supporting functions</li> |
|||
</ul> |
|||
<p>See <code>dplyr</code> for the <code>dplyr</code> operations (light testing shows they work in basic SQL use-cases but Drill’s SQL engine has issues with more complex queries).</p> |
|||
<p><strong>Drill APIs</strong>:</p> |
|||
<ul> |
|||
<li> |
|||
<code>drill_connection</code>: Setup parameters for a Drill server/cluster connection</li> |
|||
<li> |
|||
<code>drill_active</code>: Test whether Drill HTTP REST API server is up</li> |
|||
<li> |
|||
<code>drill_cancel</code>: Cancel the query that has the given queryid</li> |
|||
<li> |
|||
<code>drill_jdbc</code>: Connect to Drill using JDBC</li> |
|||
<li> |
|||
<code>drill_metrics</code>: Get the current memory metrics</li> |
|||
<li> |
|||
<code>drill_options</code>: List the name, default, and data type of the system and session options</li> |
|||
<li> |
|||
<code>drill_profile</code>: Get the profile of the query that has the given query id</li> |
|||
<li> |
|||
<code>drill_profiles</code>: Get the profiles of running and completed queries</li> |
|||
<li> |
|||
<code>drill_query</code>: Submit a query and return results</li> |
|||
<li> |
|||
<code>drill_set</code>: Set Drill SYSTEM or SESSION options</li> |
|||
<li> |
|||
<code>drill_settings_reset</code>: Changes (optionally, all) session settings back to system defaults</li> |
|||
<li> |
|||
<code>drill_show_files</code>: Show files in a file system schema.</li> |
|||
<li> |
|||
<code>drill_show_schemas</code>: Returns a list of available schemas.</li> |
|||
<li> |
|||
<code>drill_stats</code>: Get Drillbit information, such as ports numbers</li> |
|||
<li> |
|||
<code>drill_status</code>: Get the status of Drill</li> |
|||
<li> |
|||
<code>drill_storage</code>: Get the list of storage plugin names and configurations</li> |
|||
<li> |
|||
<code>drill_system_reset</code>: Changes (optionally, all) system settings back to system defaults</li> |
|||
<li> |
|||
<code>drill_threads</code>: Get information about threads</li> |
|||
<li> |
|||
<code>drill_uplift</code>: Turn a columnar query results into a type-converted tbl</li> |
|||
<li> |
|||
<code>drill_use</code>: Change to a particular schema.</li> |
|||
<li> |
|||
<code>drill_version</code>: Identify the version of Drill running</li> |
|||

<h1>Tools to Transform and Query Data with 'Apache' 'Drill'</h1> |
|||
</div> |
|||
|
|||
|
|||
<p>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:</p> |
|||
|
|||
|
|||
|
|||
<h2 class="hasAnchor" id="details"><a class="anchor" href="#details"></a>Details</h2> |
|||
|
|||
<ul> |
|||
<li><p>Schema-free JSON document model similar to MongoDB and Elasticsearch</p></li> |
|||
<li><p>Industry-standard APIs: ANSI SQL, ODBC/JDBC, RESTful APIs</p></li> |
|||
<li><p>Extremely user and developer friendly</p></li> |
|||
<li><p>Pluggable architecture enables connectivity to multiple datastores</p></li> |
|||
</ul> |
|||
<p>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.</p> |
|||
<p>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.</p> |
|||
<p>Methods are provided to work with Drill via the native JDBC & REST APIs along with R |
|||
<code>DBI</code> and <code>dplyr</code> interfaces.</p> |

\title{Tools to Transform and Query Data with 'Apache' 'Drill'} |
|||
\description{ |
|||
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: |
|||
} |
|||
\details{ |
|||
\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. |
