Changelog

4.0.2

• Changed dec-by to use remove-tail (counterfield = counterfield - x instead of counterfield = x - counterfield)

4.0.0-beta*

• Internals changes that should make query generation 2x 3x faster and more alloc friendly depending on the query

3.2.0

• Added DROP TYPE

3.1.0

• Add new cql functions

3.0.1

• add missing entry point for alter-type. Thanks @acron0 -> https://github.com/mpenet/hayt/pull/39

3.0.0

• auto-extend alia protocols if alia is detected

3.0.0-rc2

• allow any sequential in counter/collection ops

3.0.0-rc1

• upgrade to clj 1.7, removed/updated some dependencies

• Performance improvements (raw speed, mem, allocations)

• Remove prepared statements generation with values qbits.hayt/->prepared since it's used by nobody now. You can still use the ? placeholer and actually control what's happening ex: (select :foo (where {:id ?})).

2.1.0

• Add 2.1+ udt support, qbits.hayt/frozen see tests

2.0.0

Release 2.0.0 (check past logs for changes)

2.0.0-rc4

• nil queries are ignored in batch, see #30

2.0.0-rc3

• no longer depend on flatland/useful

2.0.0-rc1 - Cassandra 2.1 features

• Add qbits.hayt/create-type statement and qbits.hayt/user-type type marker for UDT values
• Slightly improved perf/ressource use
• Add tests for UDT litterals

2.0.0-beta4

• use clojure 1.6

• where1, using, set-columns, values, with now supports cassaforte like signatures (unspliced map (where1 :a 1 :b 2) or (where1 {:a 1 :b 2})}

2.0.0-beta3 - Breaking changes (backward compatible fns available)

• new where syntax, matches clojure style more closely (prefix notation), it now expects a seq of seq:

  (where [[= :a 1] [> :b 2]])
  

  It can still receive a map, but it will only assume =, a vector of 2 elements will assume =.

  (where {:a 1 :b 2})

• where' same as where but allows to skip passing the wrapping vector:

(where' [= :b 2] [> :c 3])

• where1 is the equivalent of the previous where syntax from v1 and early v2 betas. ex: (where1 {:a [> 2]}}

• Add support for paging on composite in where

(where [[= :a 1]
        [>= [:b :c :d] [1 2 3]]])

• qbits.hayt/distinct* is now variadic, thanks @pyr

(select :foo (columns (distinct* :foo :bar :baz)))

• Add support for secondary index on collections in where CASSANDRA-4511

(where [contains :l 1]}

(where [contains-key :m 2]}

• Add support for static columns in schemas

• Add sugar for operations on collections and counters

(update :foo
        (set-columns {:bar 1
                      :baz (inc-by 2)}))

(update :foo
        (set-columns {:bar 1
                      :baz (dec-by 2)}))

(update :foo
        (set-columns {:baz (prepend ["asdf"])})
        (where [[:foo "bar"]]))

(update :foo
        (set-columns {:baz (append ["asdf"])})
        (where [[:foo "bar"]]))

2.0.0-beta2

Add support for vectors in set-columns and values. Ex: (insert :foo (values [[:a 1] [:b 2]])) See Issue #19 for details.

2.0.0-beta1

Some changes require you to run against Cassandra 2.0+ !!

Breaking changes!

• Keywords as values are no longer encoded as strings and return a placeholder for a named prepared statement value. See #18

  The following

  (->raw (select :foo (where {:bar :baz})))
  

  used to generate this: "SELECT FROM foo WHERE bar = 'baz';" and now this: "SELECT FROM foo WHERE bar = :baz;"

• When using ->prepared the values for using and limit are now parameterized.

• The IN operator in where clauses when using ->prepared is now variadic (it returns the values as an array in the parameter list and uses a single ? placeholder). This is not backward compatible with C* 2.0-

(where {:foo [:in [1 2 3]]}) -> ["...WHERE foo IN ?;" [[1 2 3]]]

• apply-map has been removed from qbits.hayt.utils (it didn't make sense since we now have proper named prepared statement placeholders).

1.4.1

• fix IF NOT EXISTS clauses in create/drop statements
• add drop-columnfamily, alter-columnfamily
• Moved ? into utils.clj

1.4.0

• Added qbits.hayt.fns/? to be used as prepared statement value placeholder when using ->raw to generate prepared statements.

1.3.0

• Added create-trigger, drop-trigger
• Added keyspace qualified identifiers (ex: "select * from mykeyspace.mytable;")
• fix blob->X functions, they now accept bytebuffers and byte array as input and properly encode them

1.2.0

• Support up to cql 3.1.1 http://cassandra.apache.org/doc/old/CQL-3.0.html#a3.1.1 ** Added qbits.hayt.clause/if-exists ** Added qbits.hayt.fns/distinct* ** qbits.hayt.clause/if-not-exists is deprecated, use (qbits.hayt.clause/if-exists false) ** minor code cleanups in qbits.hayt.cql

1.1.4

• Preserve ns in when using namespaced keywords as values

1.1.3

• qbits.hayt.fns/token is now variadic, allowing composite token values

1.1.2

• Dropped dependency on clj 1.5

1.1.1

• Dropped dependency on cassandra-all, no api changes

1.1.0

• Add encoding support for byte array values

1.0.5

• Allow :primary-key :abc (value not wrapped in a vector)

1.0.4

• Minor perf. improvements

1.0.3

• ns change: qbits.hayt.dsl.verb becomes qbits.hayt.dsl.statement. This should be backward compatible as long as you don't use them directly, the aliases have been updated.

1.0.2

• Fix Collection types definitions (they were quoted)

• Fix DELETE * statement :emit (no * on delete, it now accepts nil column or :*)

1.0.1

• Internals change to accomodate cassaforte

1.0.0

• Exposed cql-raw and cql-fn, the former allows to pass arbitrary raw content as value, and the later allows to create function wrappers. These two could be usefull when/if we don't support a feature and/or you need lower level access to value/fn encoding.

• Added alias support

• Added ALTER DROP clause support

• tests, docstrings improvements

0.5.1

• Joda time support

• Moved cassandra-all in dev/test profiles

0.5.0

• CQL 3.0.3 support (create secondary index aka "CREATE CUSTOM INDEX")

• Added CAS support: if-not-exists only-if clauses https://issues.apache.org/jira/browse/CASSANDRA-5443

• Performance/ressource use improvements

• Added support for null values

• Added support for Date, blob (ByteBuffer instances), InetAddress literals

• Added noarg versions of bool clauses

• Completed/fixed coverage of blobAsX and XAsBlob functions

0.4.0-beta4

• Lift restriction on nil values (supported in C* 1.2.4+)

0.4.0-beta3

• Deprecate q->, since clauses/queries are just maps, use the usual merge/assoc/into. It will be removed in a future version likely 1.0.0

• Allow to use lowercased/dashed kw for permission, ex: :full-access or :FULL_ACCESS

• Fix :primary-key to allow composites

0.4.0-beta2

• Fix all permission queries, grant, revoke, list-permission (missing PERMISSION or PERMISSIONS)

• Renamed list-permission to list-perm

0.4.0-beta1

• cleaner AST and document (briefly) it's use in the readme
• renamed/updated the auth functions/clauses to match their cql counterpart more closely.

0.3.0

• Renamed add clause to add-column (breaking change)

• Fixed bug in batch clause (begin missing), and add missing arguments (UNLOGGED, COUNTER)

• Added rename-column grant-user, revoke-user, alter-user, create-user, drop-user, list-users, list-permissions

• Added the following clauses table, keyspace, column-family, logged, counter, resource, user, superuser, password, permission, recursive.
