## Documentation
[Minimum Viable Snippet][9]:
```clj
(ns com.example
  (:use [amazonica.aws.ec2]))

(describe-instances)

(create-snapshot :volume-id   "vol-8a4857fa"
                 :description "my_new_snapshot")
```

Amazonica reflectively delegates to the Java client library, as such it supports the complete set of remote service calls implemented by each of the service-specific AWS client classes (e.g. AmazonEC2Client, AmazonS3Client, etc.), the documentation for which can be found in the [AWS Javadocs][2]. [cljdoc function references][25] are also available.

Reflection is used to create idiomatically named Clojure Vars in the library namespaces corresponding to the AWS service. camelCase Java methods become lower-case, hyphenated Clojure functions. So for example, if you want to create a snapshot of a running EC2 instance, you'd simply
```clj
(create-snapshot :volume-id "vol-8a4857fa"
                 :description "my_new_snapshot")
```
which delegates to the [createSnapshot()][3] method of AmazonEC2Client. If the Java method on the Amazon\*Client takes a parameter, such as [CreateSnapshotRequest][4] in this case, the bean properties exposed via mutators of the form set\* can be supplied as key-value pairs passed as arguments to the Clojure function.

All of the AWS Java apis (except S3) follow this pattern, either having a single implementation method which takes an AWS Java bean as its only argument, or being overloaded and having a no-arg implementation. The corresponding Clojure function will either require key-value pairs as arguments, or be variadic and allow a no-arg invocation.

For example, AmazonEC2Client's [describeImages()][7] method is overloaded, and can be invoked either with no args, or with a [DescribeImagesRequest][8]. So the Clojure invocation would look like
```clj
(describe-images)
```
or
```clj
(describe-images :owners ["self"]
                 :image-ids ["ami-f00f9699" "ami-e0d30c89"])
```

### Conversion of Returned Types

`java.util.Collections` are converted to the corresponding Clojure collection type. `java.util.Maps` are converted to `clojure.lang.IPersistentMaps`, `java.util.Lists` are converted to `clojure.lang.IPersistentVectors`, etc.

`java.util.Dates` are automatically converted to Joda Time `DateTime` instances.

Amazon AWS object types are returned as Clojure maps, with conversion taking place recursively, so, "Clojure data all the way down."

For example, a call to
```clj
(describe-instances)
```
invokes a Java method on AmazonEC2Client which returns a `com.amazonaws.services.ec2.model.DescribeInstancesResult`. However, this is recursively converted to Clojure data, yielding a map of `Reservations`, like so:
```clj
{:owner-id "676820690883",
   :group-names ["cx"],
   :groups [{:group-name "cx", :group-id "sg-38f45150"}],
   :instances
   [{:instance-type "m1.large",
     :kernel-id "aki-825ea7eb",
     :hypervisor "xen",
     :state {:name "running", :code 16},
     :ebs-optimized false,
     :public-dns-name "ec2-154-73-176-213.compute-1.amazonaws.com",
     :root-device-name "/dev/sda1",
     :virtualization-type "paravirtual",
     :root-device-type "ebs",
     :block-device-mappings
     [{:device-name "/dev/sda1",
       :ebs
       {:status "attached",
        :volume-id "vol-b0e519c3",
        :attach-time #<DateTime 2013-03-21T22:00:56.000-07:00>,
        :delete-on-termination true}}],
     :network-interfaces [],
     :public-ip-address "164.73.176.213",
     :placement
     {:availability-zone "us-east-1a",
      :group-name "",
      :tenancy "default"},
     :private-ip-address "10.116.187.19",
     :security-groups [{:group-name "cx", :group-id "sg-38f45150"}],
     :state-transition-reason "",
     :private-dns-name "ip-10-116-187-19.ec2.internal",
     :instance-id "i-cefbe7a2",
     :key-name "cxci",
     :architecture "x86_64",
     :client-token "",
     :image-id "ami-baba68d3",
     :ami-launch-index 0,
     :monitoring {:state "disabled"},
     :product-codes [],
     :launch-time #<DateTime 2013-03-21T22:00:52.000-07:00>,
     :tags [{:value "CXCI_nightly", :key "Name"}]}],
   :reservation-id "r-8a23d6f7"}
```
If you look at the `Reservation` [Javadoc][10] you'll see that `getGroups()` returns a `java.util.List` of `GroupIdentifiers`, which is converted to a vector of maps containing keys `:group-name` and `:group-id`, under the `:groups` key. Ditto for :block-device-mappings and :tags, and so and so on...

Similar in concept to JSON unwrapping in Jackson, Amazonica supports root unwrapping of the returned data. So calling
```clj
; dynamodb
(list-tables)
```
by default would return
```clj
{:table-names ["TableOne" "TableTwo" "TableThree"]}
```
However, if you call
```clj
(set-root-unwrapping! true)
```
then single keyed top level maps will be "unwrapped" like so:
```clj
(list-tables)
=> ["TableOne" "TableTwo" "TableThree"]
```

The returned data can be "round tripped" as well. So the returned Clojure data structures can be supplied as arguments to function calls which delegate to Java methods taking the same object type as an argument. See the section below for more on this.

### Argument Coercion

Coercion of any types that are part of the java.lang wrapper classes happens transparently. So for example, Clojure's preferred longs are automatically converted to ints where required.

Clojure data structures automatically participate in the Java Collections abstractions, and so no explicit coercion is necessary. Typically when service calls take collections as parameter arguments, as in the case above, the values in the collections are most often instances of the Java wrapper classes.

When complex objects consisting of types outside of those in the `java.lang` package are required as argument parameters, smart conversions are attempted based on the argument types of the underlying Java method signature. Methods requiring a `java.util.Date` argument can take Joda Time `org.joda.time.base.AbstractInstants`, longs, or Strings (default pattern is "yyyy-MM-dd"), with conversion happening automatically.
```clj
(set-date-format! "MM-dd-yyyy")
```
can be used to set the pattern supplied to the underlying `java.text.SimpleDateFormat`.

In cases where collection arguments contain instances of AWS "model" classes, Clojure maps will be converted to the appropriate AWS Java bean instance. So for example, [describeAvailabilityZones()][5] can take a [DescribeAvailabilityZonesRequest][6] which itself has a `filters` property, which is a `java.util.List` of `com.amazonaws.services.ec2.model.Filters`. Passing the filters argument would look like:
```clj
(describe-availability-zones :filters [{:name   "environment"
                                        :values ["dev" "qa" "staging"]}])
```
and return the following Clojure collection:
```clj
{:availability-zones
 [{:state "available",
   :region-name "us-east-1",
   :zone-name "us-east-1a",
   :messages []}
  {:state "available",
   :region-name "us-east-1",
   :zone-name "us-east-1b",
   :messages []}
  {:state "available",
   :region-name "us-east-1",
   :zone-name "us-east-1c",
   :messages []}
  {:state "available",
   :region-name "us-east-1",
   :zone-name "us-east-1d",
   :messages []}
  {:state "available",
   :region-name "us-east-1",
   :zone-name "us-east-1e",
   :messages []}]}
```

### Extension points
Clojure apis built specifically to wrap a Java client, such as this one, often provide "conveniences" for the user of the api, to remove boilerplate. In Amazonica this is accomplished via the IMarshall protocol, which defines the contract for converting the returned Java result from the AWS service call to Clojure data, and the
```clj
(amazonica.core/register-coercions)
```
function, which takes a map of class/function pairs defining how a value should be coerced to a specific AWS Java bean. You can find a good example of this in the `amazonica.aws.dynamodb` namespace. Consider the following DynamoDB service call:
```clj
(get-item :table-name "MyTable"
          :key "foo")
```
The [GetItemRequest][11] takes a `com.amazonaws.services.dynamodb.model.Key` which is composed of a hash key of type `com.amazonaws.services.dynamodb.model.AttributeValue` and optional range key also of type `AttributeValue`. Without the coercions registered for `Key` and `AttributeValue` in `amazonica.aws.dynamodb` we would need to write:
```clj
(get-item :table-name "TestTable"
          :key {:hash-key-element {:s "foo"}})
```
Note that either form will work. This allows contributors to the library to incrementally evolve the api independently from the core of the library, as well as maintain backward compatibility of existing code written against prior versions of the library which didn't contain the conveniences.

### Authentication
The default authentication scheme is to use the [chained Provider class][15] from the AWS SDK, whereby authentication is attempted in the following order:
- Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
- Java System Properties - aws.accessKeyId and aws.secretKey
- Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
- Instance profile credentials delivered through the Amazon EC2 metadata service

Note that in order for the Instance Profile Metadata to be found, you must have launched the instance with a provided IAM role, and the same permissions as the IAM Role the instance was launched with will apply.

See the [AWS docs][14] for reference.

Additionally, all of the functions may take as their first argument an optional map of credentials:

```clj
(def cred {:access-key "aws-access-key"
           :secret-key "aws-secret-key"
           :endpoint   "us-west-1"})

(describe-instances cred)
```

The credentials map may contain zero or one of the following:

- `:access-key` and `:secret-key`, in which case an instance of [`BasicAWSCredentials`][20] will be created.
- `:session-token`, in which case an instance of [`BasicSessionCredentials`][21] will be created.
- `:profile`, in which case an instance of [`ProfileCredentialsProvider`][22] will be created.
- `:cred`, in which case the [`AWSCredentialsProvider`][23] instance provided will be used.
- Or rather than a Clojure map, the argument may be an actual instance or subclass of either [`AWSCredentialsProvider`][23] or [`AWSCredentials`][24].

In addition, the credentials map may contain an `:endpoint` entry. If the value of the `:endpoint` key is a lower case, hyphenated translation of one of the [Regions enums][16], [.withRegion][17] will be used to build the Client, otherwise [.withEndpointConfiguration][18] will be used.

**Note:** The first function called (for each distinct AWS service namespace, e.g. amazonica.aws.ec2) creates an Amazon*Client, which is effectively cached via memoization.  Therefore, if you explicitly pass different credentials maps to different functions, you will effectively have different Clients.

For example, to work with ec2 instances in different regions you might do something like:

```clj
(ec2/create-image {:endpoint "us-east-1"} :instance-id "i-1b9a9f71")

(ec2/create-image {:endpoint "us-west-2"} :instance-id "i-kj239d7d")
```

You will have created two AmazonEC2Clients, pointing to the two different regions. Likewise, if you omit the explicit credentials map then the DefaultAWSCredentialsProviderChain will be used. So in the following scenario you will again have two different Amazon*Clients:

```clj
(set-s3client-options :path-style-access true)

(create-bucket credentials "foo")
```

The call to `set-s3client-options` will use a DefaultAWSCredentialsProviderChain, while the `create-bucket` call will create a separate AmazonS3Client with BasicAWSCredentials.

As a convenience, users may call `(defcredential)` before invoking any service functions and passing in their AWS key pair and an optional endpoint:
```clj
(defcredential "aws-access-key" "aws-secret-key" "us-west-1")
```
All subsequent API calls will use the specified credential. If you need to execute a service call with alternate credentials, or against a different region than the one passed to `(defcredential)`, you can wrap these ad-hoc calls in the `(with-credential)` macro, which takes a vector of key pair credentials and an optional endpoint, like so:
```clj
(defcredential "account-1-aws-access-key" "aws-secret-key" "us-west-1")

(describe-instances)
; returns instances visible to account-1

(with-credential ["account-2-aws-access-key" "secret" "us-east-1"]
  (describe-instances))
; returns EC2 instances visible to account-2 running in US-East region

(describe-images :owners ["self"])
; returns images belonging to account-1
```

### Client configuration

You can supply a `:client-config` entry in the credentials map to configure the [ClientConfiguration](http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/ClientConfiguration.html) that the Amazon client uses. This is useful if you need to use a proxy.

```clj
(describe-images {:client-config {:proxy-host "proxy.address.com" :proxy-port 8080}})
```

#### localstack specific hints

When using localstack (or other AWS mocks) it may be necessary to pass some configuration to the client.

This cannot be done anymore via the `(set-s3client-options :path-style-access true)` which would lead to a `Client is immutable when created with the builder.` exception

This is particularly useful for S3, which in a typical localstack scenario needs path-style-access set to true

This is a working example, please note the config keys

```
(s3/list-buckets
  {:client-config {
    :path-style-access-enabled true
    :chunked-encoding-disabled false
    :accelerate-mode-enabled false
    :payload-signing-enabled true
    :dualstack-enabled true
    :force-global-bucket-access-enabled true}})
```

### Exception Handling
All functions throw `com.amazonaws.AmazonServiceExceptions`. If you wish to catch exceptions you can convert the AWS object to a Clojure map like so:
```clj
(try
  (create-snapshot :volume-id "vol-ahsg23h"
                   :description "daily backup")
  (catch Exception e
    (log (ex->map e))))

; {:error-code "InvalidParameterValue",
;  :error-type "Unknown",
;  :status-code 400,
;  :request-id "9ba69e16-ed63-41d4-ac02-1f6032cb64de",
;  :service-name "AmazonEC2",
;  :message
;  "Value (vol-ahsg23h) for parameter volumeId is invalid. Expected: 'vol-...'.",
;  :stack-trace "Status Code: 400, AWS Service: AmazonEC2, AWS Request ID: a5b0340a-8f37-4122-941c-ed8d5472b11d, AWS Error Code: InvalidParameterValue, AWS Error Message: Value (vol-ahsg23h) for parameter volumeId is invalid. Expected: 'vol-...'.
;  at com.amazonaws.http.AmazonHttpClient.handleErrorResponse(AmazonHttpClient.java:644)
;   at com.amazonaws.http.AmazonHttpClient.executeHelper(AmazonHttpClient.java:338)
;   at com.amazonaws.http.AmazonHttpClient.execute(AmazonHttpClient.java:190)
;   at com.amazonaws.services.ec2.AmazonEC2Client.invoke(AmazonEC2Client.java:6199)
;   at com.amazonaws.services.ec2.AmazonEC2Client.createSnapshot(AmazonEC2Client.java:1531)
;   .....
```

#### For the memory constrained
If you're especially concerned about the size of your uberjar, you can limit the transitive dependencies pulled in by the AWS Java SDK, which currently total 35mb. You'll need to exclude the entire AWS Java SDK, the Amazon Kinesis Client, and the DynamoDB streams kinesis adapter, and then add back only those services you'll be using (although core is always required). So for example, if you were only using S3, you could restrict the dependencies to only include the required jars like so:

```clj
:dependencies [[org.clojure/clojure "1.10.3"]
               [amazonica "0.3.156" :exclusions [com.amazonaws/aws-java-sdk
                                                 com.amazonaws/amazon-kinesis-client
                                                 com.amazonaws/dynamodb-streams-kinesis-adapter]]
               [com.amazonaws/aws-java-sdk-core "1.11.968"]
               [com.amazonaws/aws-java-sdk-s3 "1.11.968"]]
```

### Running the tests
As always, `lein test` will run all the tests. Note that some of the namespaces require the file `~/.aws/credentials` to be present and be of the same form as required by the official AWS tools:

```
[default]
aws_access_key_id = AKIAABCDEFGHIEJK
aws_secret_access_key = 6rqzvpAbcd1234++zyx987WUV654sRq
```

### Performance
Amazonica uses reflection extensively, to generate the public Vars, to set the bean properties passed as arguments to those functions, and to invoke the actual service method calls on the underlying AWS Client class. As such, one may wonder if such pervasive use of reflection will result in unacceptable performance. In general, this shouldn't be an issue, as the cost of reflection should be relatively minimal compared to the latency incurred by making a remote call across the network. Furthermore, typical AWS usage is not going to be terribly concerned with performance, except with specific services such as DynamoDB, RDS, SimpleDB, or SQS. But we have done some basic benchmarking against the excellent DynamoDB [rotary][13] library, which uses no explicit reflection. Results are shown below. Benchmarking code is available at [https://github.com/mcohen01/amazonica-benchmark][12]

### StepFunctions
```clj

(ns com.example
  (:use [amazonica.aws.stepfunctions]))

;this is to start the execution, then you need to run get-activity-task-result ultimately to monitor for pending requests from the state machine components
;to execute a worker task.
(start-state-machine "{\"test\":\"test\"}" "arn:aws:states:us-east-1:xxxxxxxxxx:stateMachine:test-sf")

;this will block until it returns a task in the queue from a state machine execution,
;so you need to run it in a while loop on the worker side of your app.
(let [tr (get-activity-task-result "arn:aws:states:us-east-1:xxxxxxxxx:activity:test-sf-activity")
      input (:input tr)
      token (:task-token tr)]
      (if (<validate input here....>)
        (mark-task-success "<json stuff to pipe back into the state machine....>" token)
        (mark-task-failure token))
      )
