Every step is either a <em>map</em>-step (transforming the objects in the stream), a <em>filter</em>-step (removing objects - from the stream), or a <em>sideEffect</em>-step (computing statistics about the stream).

<br/> - Gremlin was designed according to the "write once, run anywhere"-philosophy. This means that not only can all TinkerPop-enabled - graph systems execute Gremlin traversals, but also, every Gremlin traversal can be evaluated as either a real-time database query - or as a batch analytics query. The former is known as an <em>online transactional process</em> (<a href="https://en.wikipedia.org/wiki/Online_transaction_processing";>OLTP</a>) and the latter as an <em>online analytics - process</em> (<a href="https://en.wikipedia.org/wiki/Online_analytical_processing";>OLAP</a>). This universality is made possible by the Gremlin traversal machine. This distributed, graph-based <a href="https://en.wikipedia.org/wiki/Virtual_machine#Abstract_virtual_machine_techniques";>virtual machine</a> - understands how to coordinate the execution of a multi-machine graph traversal. Moreover, not only can the execution either be OLTP or - OLAP, it is also possible for certain subsets of a traversal to execute OLTP while others via OLAP. The benefit is that the user does - not need to learn both a database query language and a domain-specific BigData analytics language (e.g. Spark DSL, MapReduce, etc.). - Gremlin is all that is required to build a graph-based application because the Gremlin traversal machine will handle the rest. - <br/><br/> - <center><img src="images/oltp-and-olap.png" style="width:80%;" class="img-responsive"></center> - </div> - <br/> - <div class="container"> - <a name="imperative-and-declarative-traversals"></a> - <h3>Imperative and Declarative Traversals</h3> - <br/> - <div class="row"> - <div class="col-sm-7 col-md-8"> - A Gremlin traversal can be written in either an <em>imperative</em> (<a href="https://en.wikipedia.org/wiki/Imperative_programming";>procedural</a>) manner, a <em>declarative</em> (<a href="https://en.wikipedia.org/wiki/Declarative_programming";>descriptive</a>) manner, - or in a hybrid manner containing both imperative and declarative aspects. An imperative Gremlin traversal tells the traversers how to proceed at each step in the traversal. For instance, - the imperative traversal on the right first places a traverser at the vertex denoting Gremlin. That traverser then splits itself across all of Gremlin's collaborators that are not Gremlin - himself. Next, the traversers walk to the managers of those collaborators to ultimately be grouped into a manager name count distribution. This traversal is imperative in that it tells the - traversers to "go here and then go there" in an explicit, procedural manner. - </div> - <div class="col-sm-5 col-md-4"> - <pre style="padding:10px;"> -<code class="language-gremlin">g.V().has("name","gremlin").as("a"). -out("created").in("created"). -where(neq("a")). -in("manages"). -groupCount().by("name")</code> -</pre> - </div> - </div> - <p/> - <div class="row"> - <div class="col-sm-5 col-md-4"> - <pre style="padding:10px;"> -<code class="language-gremlin">g.V().match( -as("a").has("name","gremlin"), -as("a").out("created").as("b"), -as("b").in("created").as("c"), -as("c").in("manages").as("d"), -where("a",neq("c"))). -select("d"). -groupCount().by("name")</code> -</pre> - </div> - <div class="col-sm-7 col-md-8"> - A declarative Gremlin traversal does not tell the traversers the order in which to execute their walk, but instead, allows each traverser to select a pattern to execute from a collection - of (potentially nested) patterns. The <a href="http://tinkerpop.apache.org/docs/current/reference/#match-step";>declarative traversal</a> on the left yields the same result as the imperative traversal above. However, the declarative traversal has the added benefit - that it leverages not only a compile-time query planner (like imperative traversals), but also a runtime query planner that chooses which traversal pattern to execute next based on the - historic statistics of each pattern -- favoring those patterns which tend to reduce/filter the most data. - </div> - </div> - <br/> - The user can write their traversals in any way they choose. However, ultimately when their traversal is compiled, and depending on the underlying execution engine - (i.e. an OLTP graph database or an OLAP graph processor), the user's traversal is rewritten by a set of <em><a href="http://tinkerpop.apache.org/docs/current/reference/#traversalstrategy";>traversal strategies</a></em> which do their best to determine the most optimal execution - plan based on an understanding of graph data access costs as well as the underlying data systems's unique capabilities (e.g. fetch the Gremlin vertex from the graph database's "name"-index). - Gremlin has been designed to give users flexibility in how they express their queries and graph system providers flexibility in how to efficiently evaluate traversals against their TinkerPop-enabled data system. - </div> - <br/> - <div class="container"> - <a name="host-language-embedding"></a> - <h3>Host Language Embedding</h3> - <br/> - <div class="row"> - <div class="col-sm-5 col-md-4"> - <img src="images/gremlin-language-variants.png" class="img-responsive"> - </div> - <div class="col-sm-7 col-md-8"> - Classic database query languages, like <a href="https://en.wikipedia.org/wiki/SQL";>SQL</a>, were conceived as being fundamentally different from the programming languages that would - ultimately use them in a production setting. For this reason, classical databases require the developer to code both in their native programming - language as well as in the database's respective query language. An argument can be made that the difference between "query languages" and - "programming languages" are not as great as we are taught to believe. Gremlin unifies this divide because traversals can be written in any - programming language that supports function <a href="https://en.wikipedia.org/wiki/Function_composition";>composition</a> and <a href="https://en.wikipedia.org/wiki/Nested_function";>nesting</a> (which every major programming language supports). In this way, the user's - Gremlin traversals are written along side their application code and benefit from the advantages afforded by the host language and its tooling - (e.g. type checking, syntax highlighting, dot completion, etc.). Various <a href="http://tinkerpop.apache.org/docs/current/tutorials/gremlin-language-variants/";>Gremlin language variants</a> exist including: Gremlin-Java, Gremlin-Groovy, <a href="http://tinkerpop.apache.org/docs/current/reference/#gremlin-python";>Gremlin-Python</a>, - <a href="https://github.com/mpollmeier/gremlin-scala";>Gremlin-Scala</a>, etc. - </div> - <div class="col-md-12"> - <p><br/>The first example below shows a simple Java class. Note that the Gremlin traversal is expressed in Gremlin-Java and thus, is part of the user's application code. There is no need for the - developer to create a <code>String</code> representation of their query in (yet) another language to ultimately pass that <code>String</code> to the graph computing system and be returned a result set. Instead, - traversals are embedded in the user's host programming language and are on equal footing with all other application code.

The traversal source definition determines where the traversal executes. Once a traversal source is - defined it can be used over and over again in a manner analogous to a database connection. The ultimate effect is that the user "feels" that their data and their traversals are all - co-located in their application and accessible via their application's native programming language.
