+ <h1>Drill Overview</h1>
+ <p>
+ Apache Drill provides low latency ad-hoc queries to many
different data sources, including nested data. Inspired by Google's Dremel,
Drill is designed to scale to 10,000 servers and query petabytes of data in
seconds.
+ </p>
+ </div>
+
+ <div class="int_text">
+
+ <h2>High Level Concept<h2>
+
+ <p>There is a strong need in the market for low-latency
interactive analysis of large-scale datasets, including nested data (eg, JSON,
Avro, Protocol Buffers). This need was identified by Google and addressed
internally with a system called Dremel.</p>
+
+ <p>In recent years open source systems have emerged to address the
need for scalable batch processing (Apache Hadoop) and stream processing
(Storm, Apache S4). Apache Hadoop, originally inspired by Google's internal
MapReduce system, is used by thousands of organizations processing large-scale
datasets. Apache Hadoop is designed to achieve very high throughput, but is not
designed to achieve the sub-second latency needed for interactive data analysis
and exploration. Drill, inspired by Google's internal Dremel system, is
intended to address this need.</p>
+
+ <p>It is worth noting that, as explained by Google in the original
paper, Dremel complements MapReduce-based computing. Dremel is not intended as
a replacement for MapReduce and is often used in conjunction with it to analyze
outputs of MapReduce pipelines or rapidly prototype larger computations.
Indeed, Dremel and MapReduce are both used by thousands of Google employees.</p>
+
+ <p>Like Dremel, Drill supports a nested data model with data
encoded in a number of formats such as JSON, Avro or Protocol Buffers. In many
organizations nested data is the standard, so supporting a nested data model
eliminates the need to normalize the data. With that said, flat data formats,
such as CSV files, are naturally supported as a special case of nested data.</p>

+ <h1>Architecture</h1>
+ <p>
+ Apache Drill is a low latency distributed query engine for
large-scale datasets, including structured and semi-structured/nested data.
Inspired by Google's Dremel, Drill is designed to scale to several thousands of
nodes and query petabytes of data at interactive speeds that BI/Analytics
environments require.
+ </p>
+ </div>
+
+ <div class="int_text">
+
+ <h2>High-Level Architecture<h2>
+
+ <p>Drill includes a distributed execution environment, purpose
built for large-scale data processing. At the core of Apache 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>A Drillbit service can be installed and run on all of the
required nodes in a Hadoop cluster to form a distributed cluster environment.
When a Drillbit runs on each data node in the 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>Note that though Drill works in a Hadoop cluster environment, Drill is not
tied to Hadoop and can run in any distributed cluster environment. The only
pre-requisite for Drill is Zookeeper.</p>
+
+ <h2>Query Flow in Drill</h2>
+
+ <p>
+
+ The following image represents the flow of a Drill query:
+ <img src="images/arc-1.jpg" alt="The flow of a Drill query"
width="550">
+
+ The flow of a Drill query typically involves the following
steps:
+
+ </p>
+ <ul class="num">
+ <li>The Drill client issues a query. A Drill client is a JDBC,
ODBC, command line interface or a REST API. Any Drillbit in the cluster can
accept queries from the clients. There is no master-slave concept.</li>
+ <li>The Drillbit then parses the query, optimizes it, and
generates a distributed query plan that is optimized for fast and efficient
execution.</li>
+ <li>The Drillbit that accepts the query becomes the driving
Drillbit node for the request. It gets a list of available Drillbit nodes in
the cluster from ZooKeeper. The driving Drillbit determines the appropriate
nodes to execute various query plan fragments to maximize data locality.</li>
+ <li> The Drillbit schedules the execution of query fragments
on individual nodes according to the execution plan.</li>
+ <li>The individual nodes finish their execution and return
data to the driving Drillbit.</li>
+ <li>The driving Drillbit streams results back to the
client.</li>
+ </ul>
+
+ <h2>Core Modules within a Drillbit</h2>
+ <p>The following image represents Drillbit components:</p>
+
+ <img src="images/arc-2.jpg" alt="Drillbit components"
width="525">
+
+ <p>⢠RPC end point: Drill exposes a low overhead protobuf-based
RPC protocol to communicate with the clients. Additionally, a C++ and Java API
layers are also available for the client applications to interact with Drill.
Clients can communicate to a specific Drillbit directly or go through a
ZooKeeper quorum to discover the available Drillbits before submitting queries.
It is recommended that the clients always go through ZooKeeper to shield
clients from the intricacies of cluster management, such as the addition or
removal of nodes.</p>
+ <p>⢠SQL parser: Drill uses Optiq, the open source framework, to
parse incoming queries. The output of the parser component is a language
agnostic, computer-friendly logical plan that represents the query.</p>
+ <p>⢠Optimizer: Drill uses various standard database
optimizations such as rule based/cost based, as well as data locality and other
optimization rules exposed by the storage engine to re-write and split the
query. The output of the optimizer is a distributed physical query plan that
represents the most efficient and fastest way to execute the query across
different nodes in the cluster.</p>
+ <p>⢠Execution engine: Drill provides a MPP execution engine
built to perform distributed query processing across the various nodes in the
cluster. </p>
+ <p>⢠Storage plugin interfaces: Drill serves as a query layer on
top of several data sources. Storage plugins in Drill represent the
abstractions that Drill uses to interact with the data sources. Storage plugins
provide Drill with the following information:</p>
+
+ <p class="l1">
+ ⢠Metadata available in the source<br>
+ ⢠Interfaces for Drill to read from and write to data
sources<br>
+ ⢠Location of data and a set of optimization rules to help
with efficient and faster execution of Drill queries on a specific data source
+ </p>
+ <p>
+ In the context of Hadoop, Drill provides storage plugins for
files and HBase/M7. Drill also integrates with Hive as a storage plugin since
Hive provides a metadata abstraction layer on top of files, HBase/M7, and
provides libraries to read data and operate on these sources (SerDes and UDFs).
+ </p>
+
+ <p>When users query files and HBase/M7 with Drill, they can do it
directly or go through Hive if they have metadata defined there. Drill
integration with Hive is only for metadata. Drill does not invoke the Hive
execution engine for any requests. </p>
+
+ <p>⢠Distributed cache: Drill uses a distributed
cache to manage metadata (not the data) and configuration information across
various nodes. Sample metadata information that is stored in the cache includes
query plan fragments, intermediate state of the query execution, and
statistics. Drill uses Infinispan as its cache technology.</p>
+
+ <h2>Architectural Highlights</h2>
+
+ <p>
+ The goal for Drill is to bring the SQL ecosystem and performance of
the relational systems to Hadoop scale data WITHOUT compromising on the
flexibility of Hadoop/NoSQL systems. There are several core architectural
elements in Apache Drill that make it a highly flexible and efficient query
engine.
+ </p>
+
+ <h3>Flexibility</h3>
+ <ul>
+ <li><p><strong>Dynamic schema
discovery</strong>: Drill does not require schema or type specification for the
data in order to start the query execution process. Instead, Drill starts
processing the data in units called record-batches and discovers the schema on
the fly during processing. Self-describing data formats such as Parquet, JSON,
AVRO and NoSQL databases have schema specified as part of the data itself,
which will be leveraged by Drill dynamically at the query time. Schema can
change over the course of a Drill query, so all of the Drill operators are
designed to reconfigure themselves when such schema changing events occur.
+ </p>
+<li><p><strong>Flexible data model</strong>: Drill is purpose-built from
ground up for complex/multi-structured data commonly seen in Hadoop/NoSQL
applications such as social/mobile, clickstream, logs and sensor equipped IOT.
From a user point of view, Drill allows access to nested data attributes, just
like SQL columns, and provides intuitive extensions to easily operate on them.
From an architecture point of view, Drill provides a flexible hierarchical
columnar data model that can represent complex, highly dynamic and evolving
data models and allows efficient processing of it without need to flatten or
materialize it either design time or at execution time. Relational data in
Drill is treated as a special or simplified case of complex/multi-structured
data.
+ </p>
+<li><p><strong>Decentralized metadata</strong>: Unlike other SQL-on-Hadoop
technologies or any traditional relational database, Drill does not have a
centralized metadata requirement. In order to query data through Drill, users
do not need to create and manage tables/views in a metadata repository, or rely
on a database administrator group for such a function. <br><br>
+Drill metadata is derived from the storage plugins that correspond to data
sources. Drill supports a varied set of storage plugins that provide a spectrum
of metadata ranging from full metadata such as for Hive, partial metadata such
as for HBase, or no central metadata such as for files. <br><br>
+De-centralized metadata also means that Drill is NOT tied to a single Hive
repository either. Users can query from multiple Hive repositories in a single
query and then combine data with information from HBase tables or a file in the
distributed file system. <br><br>
+Users also have the ability to create metadata (tables/views/databases) within
Drill using the SQL DDL syntax. De-centralized metadata is applicable during
metadata creation. Drill allows persisting metadata in one of the underlying
data sources. <br><br>
+From a client access perspective, Drill metadata is organized just like a
traditional DB <br>(Databases->Tables/Views->Columns). The metadata is
accessible through the ANSI standard INFORMATION_SCHEMA database.
+ </p>
+<li><p><strong>Extensibility</strong>: Drill provides an extensible
architecture at all layers, including storage plugin layer, query layer, query
optimization/execution, and client APIs. You can customize any layer for the
specific needs of an organization or you can extend the layer to a broader
array of use cases. <br><br>
+Drill provides a built in classpath scanning and plugin concept to add
additional storage plugins, functions, and operators with minimal
configuration.
+<br><br>
+The following list provides a few examples of Drill's extensible architectural
capabilities:
+<ul>
+<li>A high performance Java API to implement custom UDFs/UDAFs
+<li>Ability to go beyond Hadoop by implementing custom storage plugins to
other data sources such as Oracle/MySQL or NoSQL stores, such as Mongo or
Cassandra
+<li>An API to implement custom operators
+<li>Support for direct execution of strongly specified JSON based logical and
physical plans to help with the simplification of testing, and to enable
integration of alternative query languages other than SQL.
+ </p>
+</ul>
+
+</ul>
+
+<h3>Performance</h3>
+
+<p>Drill is designed from the ground up for high performance on large
datasets. Few core elements of Drill processing that help Drill achieve its
performance include:</p>
+<ul>
+<li><p><strong>Distributed engine</strong>: Drill provides a powerful
distributed execution engine for processing queries. Users can submit requests
to any node in the cluster. You can simply add new nodes to the cluster to
scale for larger volumes of data, support more users or to improve performance.
+ </p>
+<li><p><strong>Columnar execution</strong>: Drill optimizes for both columnar
storage and execution by using an in-memory data model that is hierarchical and
columnar. When working with data stored in columnar formats such as Parquet,
Drill avoids disk access for columns that are not involved in an analytic
query. Drill also provides an execution layer that performs SQL processing
directly on columnar data without row materialization. The combination of
optimizations for columnar storage and direct columnar execution significantly
lowers memory footprints and provides faster execution of BI/Analytic type of
workloads.
+ </p>
+<li><p><strong>Vectorization</strong>: Rather than operating on single values
from a single table record at one time, vectorization in Drill allows the CPU
to operate on vectors, referred to as a Record Batches. Record Batches are
arrays of values from many different records. The technical basis for
efficiency of vectorized processing is modern chip technology with
deep-pipelined CPU designs. Keeping all pipelines full to achieve efficiency
near peak performance is something impossible to achieve in traditional
database engines, primarily due to code complexity.
+ </p>
+<li><p><strong>Runtime compilation</strong>:
+Runtime compilation is faster compared to the interpreted execution. Drill
generates highly efficient custom code for every single query for every single
operator. Here is a quick overview of the Drill compilation/code generation
process at a glance.
+<br><img src="images/drillcompiler.png" width="500">
+ </p>
+<li><p><strong>Optimistic and pipelined query execution</strong>: Drill adopts
an optimistic execution model to process queries. Drill assumes that failures
are infrequent within the short span of a query and therefore does not spend
time creating boundaries or checkpoints to minimize recovery time. Failures at
node level are handled gracefully. In the instance of a single query failure,
the query is rerun. Drill execution uses a pipeline model where all tasks are
scheduled at once. The query execution happens in-memory as much as possible to
move data through task pipelines, persisting to disk only if there is memory
overflow.
+ </p>
+</ul>
