Build Status codecov


A Query builder with support for Cassandra, using the original Laravel API. This library extends the original Laravel classes, so it uses exactly the same methods.

  • Examples


Make sure you have the DataStax PHP Driver for Apache Cassandra installed. You can find installation instructions at datastax repo.

Note: datastax php-driver works with php version 5.6.*, 7.0.* and 7.1.* only

Installation using composer

composer require shso/laravel-cassandra

And add the service provider in config/app.php:

# config/app.php
providers: [


Change your default database connection name in config/database.php:

# config/database.php
'default' => env('DB_CONNECTION', 'cassandra'),

And add a new cassandra connection:

# config/database.php
'cassandra' => [
    'driver' => 'cassandra',
    'host' => env('DB_HOST', ''),
    'port' => env('DB_PORT', 9042),
    'keyspace' => env('DB_DATABASE', 'cassandra_db'),
    'username' => env('DB_USERNAME', ''),
    'password' => env('DB_PASSWORD', ''),
    'page_size' => '5000',
    'consistency' => 'local_one',
    'timeout' => null,
    'connect_timeout' => 5.0,
    'request_timeout' => 12.0,

Note: you can enter all of your nodes like:

# .env

Note: you can choose one of the consistency levels below:

any three local_qourum local_one
one qourum each_qourum serial
two all local_serial

Query Builder

The database driver plugs right into the original query builder. When using cassandra connections, you will be able to build fluent queries to perform database operations.

$emp = DB::table('emp')->get();
$emp = DB::table('emp')->where('emp_name', 'Christy')->first();

If you did not change your default database connection, you will need to specify it on each query.

$emp = DB::connection('cassandra')->table('emp')->get();


Retrieving All Records

$emp = DB::table('emp')->all();

Indexing columns

CREATE INDEX creates a new index on the given table for the named column.


Selecting columns

$emp = DB::table('emp')->where('emp_no', '>', 50)->select('emp_name', 'emp_no')->get();
$emp = DB::table('emp')->where('emp_no', '>', 50)->get(['emp_name', 'emp_no']);


The WHERE clause specifies which rows to query. In the WHERE clause, refer to a column using the actual name, not an alias. Columns in the WHERE clause need to meet one of these requirements:

  • The partition key definition includes the column.

  • A column that is indexed using CREATE INDEX.

$emp = DB::table('emp')->where('emp_no', '>', 50)->take(10)->get();

And Statements

$emp = DB::table('emp')->where('emp_no', '>', 50)->where('emp_name', '=', 'Christy')->get();

Using Where In With An Array

$emp = DB::table('emp')->whereIn('emp_no', [12, 17, 21])->get();

Order By

ORDER BY clauses can select a single column only. Ordering can be done in ascending or descending order, default ascending, and specified with the ASC or DESC keywords. In the ORDER BY clause, refer to a column using the actual name, not the aliases.

$emp = DB::table('emp')->where('emp_name', 'Christy')->orderBy('emp_no', 'desc')->get();


We can use limit() and take() for limiting the query.

$emp = DB::table('emp')->where('emp_no', '>', 50)->take(10)->get();
$emp = DB::table('emp')->where('emp_no', '>', 50)->limit(10)->get();


Distinct requires a primary key field for which to return the distinct values.

$emp = DB::table('emp')->distinct()->get(['emp_id']);

Distinct can be combined with where:

$emp = DB::table('emp')->where('emp_sal', 45000)->distinct()->get(['emp_name']);


$number = DB::table('emp')->count();

Count can be combined with where:

$sal = DB::table('emp')->where('emp_sal', 45000)->count();


$sal = DB::table('emp')->truncate();

Filtering a collection set, list, or map

You can index the collection column, and then use the CONTAINS condition in the WHERE clause to filter the data for a particular value in the collection.

$emp = DB::table('emp')->where('emp_name', 'contains', 'Christy')->get();

After indexing the collection keys in the venues map, you can filter on map keys.

$emp = DB::table('emp')->where('todo', 'contains key', '2014-10-02 06:30:00+0000')->get();

Raw Query

The CQL expressions can be injected directly into the query.

$emp = DB::raw('select * from emp');

Inserts, updates and deletes

Inserting, updating and deleting records works just like the original QB.


    ->insertCollection('set', 'phn', [123, 1234, 12345])
    ->insertCollection('map', 'friends', [['John', 'Male'], ['Eli', 'Female']])
        'emp_id' => 11,
        'emp_name' => 'Christy',
        'emp_phone' => 12345676890,
        'emp_sal' => 500


To update a model, you may retrieve it, change an attribute, and use the update method.

    ->where('emp_id', 11)
        'emp_city' => 'kochi',
        'emp_name' => 'Christy jos',
        'emp_phone' =>  123456789

Updating a collection set, list, and map

Update collections in a row. The method will be like

updateCollection(collection_type, column_name, operator, value);

Collection_type is any of set, list or map.

Column_name is the name of column to be updated.

Operator is + or -, + for adding the values to collection and - to remove the value from collection.

Value can be associative array for map type and array of string/number for list and set types.

DB::table('users')->where('id', 1)
    ->updateCollection('set', 'phn', '+', [123, 1234,12345])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('set', 'phn', '-', [123])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('list', 'hobbies', '+', ['reading', 'cooking', 'cycling'])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('set', 'phn', '+', [123, 1234,12345])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('set', 'phn', '-', [123])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('list', 'hobbies', '+', ['reading', 'cooking', 'cycling'])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('list', 'hobbies', '-', ['cooking'])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('map', 'friends', '+', [['John', 'Male'], ['Rex', 'Male']])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('map', 'friends', '-', ['John'])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('map', 'friends', '+', [['John', 'Male'], ['Rex', 'Male']])->update();

DB::table('users')->where('id', 1)
    ->updateCollection('map', 'friends', '-', ['John'])->update();


To delete a model, simply call the delete method on the instance. We can delete the rows in a table by using deleteRow method:

$emp = DB::table('emp')->where('emp_city', 'Kochi')->deleteRow();

We can also perform delete by the column in a table using deleteColumn method:

$emp = DB::table('emp')->where('emp_id', 3)->deleteColumn();


I have created a docker container which has php7.0 and cassandra php driver installed. It is prefered to use docker for testing purposes.

Also there is a run executable which is there to ease use of docker container. It checks everything and makes sure all dependancies and the cassandra server are up and running and then passes your command to the container.
