TL;DR

Elastisch is a battle tested, small but feature rich and well documented Clojure client for ElasticSearch. It supports virtually every Elastic Search feature and has solid documentation.

2.1.0 is feature release.

Changes between Elastisch 2.0.x and 2.1.0

Clojure 1.4 Support Dropped

Elastisch no longer officially supports Clojure 1.4. Most of the functionality still works well on that version but please don’t file bugs specific to that version.

Allow :index key in update-aliases (native)

clojurewerkz.elastisch.native.index/update-aliases expects indices to be added to be specified in the :indices key while the respective REST function uses :index. This can have unexpected results, namely the creation of the respective alias for all indices. It is now possible to supply either :index or :indices to the function.

GH issue: #108.

Update with Partial Document via native API

clojurewerkz.elastisch.native.document/update-with-partial-doc is a new function in the Native Client (existed before in the REST API) that performs partial updates:

1
2
3

(require '[clojurewerkz.elastisch.native.document :as doc])

(doc/update-with-partial-doc conn "people" "person" "1" {:country "Sweden"})

Note that the REST API should now be called without wrapping the document in a :doc key. I.e. change {:doc {:field-to-update "Update"}} to {:field-to-update "Update"}.

Contributed by Sandeep Jagtap and Henrik Lundahl.

Ability to Specify Aliases In index.create-template

clojurewerkz.elastisch.rest.index.create-template now supports the :aliases option:

1
2
3

(require '[clojurewerkz.elastisch.rest.index :as idx])

(idx/create-template conn "accounts" {:template "account*" :settings {:index {:refresh_interval "60s"}} :aliases {:account-alias {}}})

Contributed by Jeffrey Erikson.

clj-http Update

clj-http dependency has been upgraded to version 1.0.x.

Allow Retry On Conflict Option

Updates and upserts now allow the retry-on-conflict option to be set. This helps to work around Elasticsearch version conflicts.

GH issue: #119.

REST API Bulk Indexing Filters Out Operation Keys

clojurewerkz.elastisch.rest.bulk/bulk-index now filters out all operation/option keys so that they don’t get stored in the document body.

GH issue: #116.

Contributed by Michael Nussbaum (Braintree).

New Line in Multi-Search REST API

ElasticSearch Multi Search REST API endpoint is sensitive to the trailing new line. When it is missing, the response contains one result too few.

Elastisch now makes sure to append a new line to Multi Search request bodies.

Correct async-put in Native Client

Native client’s document/async-put no longer fails with an exception.

Contributed by Nikita Burtsev.

ElasticSearch Native Client Upgrade

Elastisch now depends on ElasticSearch native client version 1.4.x.

Single-Bucket Aggregation Fix in the Native Client

Child aggregations in single-bucket aggregations (i.e. “global”) are no longer silently dropped.

Contributed by Yannick Scherer (StyleFruits).

Aggregations Support in the Native Client

Native client now has support for aggregations.

The API is the same as in the REST client.

Note that ElasticSearch 1.2 has 26 aggregations. Currently only the most commonly used ones are supported but support for more types will be added eventually. The supported types are:

• Avg
• Max
• Min
• Sum
• Stats
• Extended stats
• Cardinality, value count
• Percentiles
• Histogram
• Date Histogram
• Range
• Date Range
• Terms
• Missing
• Global

Multi-Search Support in the Native Client

Native client now has support for multi-search.

The API is the same as in the REST client except that the functions are in the clojurewerkz.elastisch.native.multi.

Extra Options on Upserts

clojurewerkz.elastisch.native.document/upsert now accepts a map of extra options, e.g. parent document ID:

1

(doc/upsert conn index-name index-type id doc {:parent parent-id})

Terms Query Helper

clojurewerkz.elastisch.query/terms is a newly added alias for clojurewerkz.elastisch.query/term when used with a collection.

Contributed by Martin Klepsch.

Remove Alias Now Works in Native Client

Bug fixed in native client for removing aliases from indices and improved inline documentation. See aliases in the guide.

(doc/search conn index type
            {:query (q/query-string :query "software" :default_field "summary")
             :highlight {:fields {:summary {}}}})

Per Connection clj-http Options in REST Client

It is now possible to specify clj-http options for REST API connections, e.g. to specify a timeout:

1
2

(esr/connect "http://127.0.0.1:9200/" {:conn-timeout 1000
                                       :basic-auth ["username" "pa$$w0rd"]})

Source Filtering Support in Native Client

Native client now supports source filtering just like the REST API client:

1
2
3
4

(doc/search conn index-name mapping-type
            :query   (q/match-all)
            :sort    {"first-name" "asc"}
            :_source ["first-name" "age"])

                                 "planet" "biography"
                                 "last-name" "username"]})

GH issue: #73.

Search Can Return Fields and Source

Previously a search would return either the source document, or specific fields and not both. There are certain circumstances where having both are beneficial, for example when searching for a child document and you want to include the parent ID:

1
2
3

(require '[clojurewerkz.elastisch.native.document :as esd])

(esd/search conn "index" "child-type" :query (q/match-all) :fields ["_parent"])

The above would return the parent document ID in the :_parent field of each hit, but would not return the document itself. You can now have both by:

1

(esd/search conn "index" "child-type" :query (q/match-all) :fields ["_parent" "_source"])

Now the parent ID is in the :_parent field of each hit, and the matching document will be in :_source as per a normal search.

TL;DR

Cassaforte is a Clojure client for Apache Cassandra. It is built around CQL 3 and focuses on ease of use. You will likely find that using Cassandra from Clojure has never been so easy.

2.0.0-rc2 is a release candidate for 2.0.

Changes between 2.0.0-rc1 and 2.0.0-rc2

Fixes Race Condition in Async Operations

Hayt Upgraded to 2.0

Hayt was upgraded to 2.0.

clojurewerkz.cassandra.cql/iterate-table Now Terminates

clojurewerkz.cassandra.cql/iterate-table no longer produces an infinite sequence.

URI Connections

It is now possible to connect to a node and switch to a namespace using a URI string:

1
2
3
4
5

(ns cassaforte.docs
  (:require [clojurewerkz.cassaforte.client :as cc]))

;; connects to node 127.0.0.1:9042 and uses "new_cql_keyspace" as keyspace
(cc/connect-with-uri "cql://127.0.0.1:9042/new_cql_keyspace")

Cassandra 2.1 Compatibility

Cassaforte 2.0 is compatible with Cassandra 2.1.

Prepared Statement Cache Removed

Prepared statement cache was affecting client correctness in some cases and was removed.

Policy Namespace

Policy-related functions from clojurewerkz.cassaforte.client were extracted into clojurewerkz.cassaforte.policies:

1
2
3

(require '[clojurewerkz.cassaforte.policies :as cp])

(cp/exponential-reconnection-policy 100 1000)

  (cp/token-aware-policy p))

DataStax Java Driver Update

DataStax Java driver has been updated to 2.1.x.

Cassandra Sessions Compatible with with-open

Session#shutdown was renamed to Session#close in cassandra-driver-core. Cassaforte needs to be adapted to that.

Contributed by Jarkko Mönkkönen.

TLS and Kerberos Support

Cassaforte now supports TLS connections and Kerberos authentication via DataStax CQL extensions.

The :ssl connection option now can be a map with two keys:

• :keystore-path
• :keystore-password

which provide a path and password to a JDK KeyStore on disk, created with keytool.

Optionally, an instance of SSLOptions can be provided via the :ssl-options connection option.

Contributed by Max Barnash.

Clojure 1.4 and 1.5 Support Dropped

Cassaforte now requires Clojure 1.6.0.

Collections Converted to Clojure Data Structures

Cassandra maps, sets and lists are now automatically converted to their immutable Clojure counterparts.

Atomic Batches Support

Atomic batches are now easier to use with Cassaforte:

1
2
3
4
5
6
7

(require '[clojurewerkz.cassaforte.client :as client])
(require '[clojurewerkz.cassaforte.cql :as cql :refer :all])
(require '[clojurewerkz.cassaforte.query :refer :all])
(require '[qbits.hayt.dsl.statement :as hs])

(let [s (client/connect ["127.0.0.1"])]
  (cql/atomic-batch s (queries
                         (hs/insert :users (values {:name "Alex" :city "Munich" :age (int 19)}))
                         (hs/insert :users (values {:name "Fritz" :city "Hamburg" :age (int 28)})))))

Query DSL Taken From Hayt 2.0

Cassaforte no longer tries to support query condition DSLs for both Hayt 1.x and Hayt 2.0. Hayt 2.0 is the only supported flavour now and is the future.

Some examples of the changes:

;; before
(where :name "Alex" :city "Munich")

;; after
(where [[= :name "Alex"]
        [= :city "Munich"]])
(where {:name "Alex" :city "Munich"})


;; before
(where :name "Alex" :age [> 25])

;; after
(where [[= :name "Alex"]
        [> :age  25]])

;; before
(where :name "Alex" :city [:in ["Munich" "Frankfurt"]])

;; after
(where [[= :name "Alex"]
        [:in :city ["Munich" "Frankfurt"]]])

As it’s easy to see, the new condition style closer resembles Clojure itself and thus was a reasonable decision on behalf of Hayt developers.

Keyspace as Option

It is now possible to choose keyspace via an option:

1
2
3
4
5

(ns cassaforte.docs
  (:require [clojurewerkz.cassaforte.client :as cc]))

(let [conn (cc/connect {:hosts ["127.0.0.1"] :keyspace "a-keyspace"})]
  )

Contributed by Max Barnash (DataStax).

Clojure 1.7.0-alpha2+ Compatibility

Cassaforte is now compatible with Clojure 1.7.0-alpha2 and later versions.

GH issue: #60.

Support for overriding default SSL cipher suites

Providing a :cipher-suites key in the :ssl connection option allows to specify cipher suites that are enabled when connecting to a cluster with SSL. The value of this key is a Seq of Strings (e.g. a vector) where each item specifies a cipher suite:

1
2
3
4
5
6

(ns cassaforte.docs
  (:require [clojurewerkz.cassaforte.client :as cc]))

(cc/build-cluster {:ssl {:keystore-path "path/to/keystore"
                         :keystore-password "password"}})]
                         :cipher-suites ["TLS_RSA_WITH_AES_128_CBC_SHA"]}}

The :cipher-suites key is optional and may be omitted, in which case Datastax Java driver’s default cipher suites (com.datastax.driver.core.SSLOptions/DEFAULT_SSL_CIPHER_SUITES) are enabled.

This can be used to work around the need to install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files required by the default set of cipher suites. TLS_RSA_WITH_AES_128_CBC_SHA is a suite in the default set that works with the standard JCE. E.g. by specifying just that one, as in the code example, the standard JCE is enough.

GH issue: #61.

Money is a Clojure library that deals with monetary amounts and currencies, built on top of Joda Money.

1.7.0 is a minor release.

Changes between 1.6.0 and 1.7.0

ZMK Currency Removed

In accordance with a Joda Money 0.10.0 change, ZMK is no longer on the list of known currencies (use ZMW instead).

Joda Money 0.10

Joda Money was upgraded to 0.10.0.

Changes between 1.5.0 and 1.6.0

Clojure 1.6 By Default

The project now depends on org.clojure/clojure version 1.6.0. It is still compatible with Clojure 1.4 and if your project.clj depends on a different version, it will be used, but 1.6 is the default now.

We encourage all users to upgrade to 1.6, it is a drop-in replacement for the majority of projects out there.

Changes between 1.4.0 and 1.5.0

<, >, <=, >= now return a boolean on the 1-arg arity, as per docstring.
