DataTable

The primary data structure used to store analytics data in Matomo (formerly Piwik).

The Basics

DataTables consist of rows and each row consists of columns. A column value can be a numeric, a string or an array.

Every row has an ID. The ID is either the index of the row or ID_SUMMARY_ROW.

DataTables are hierarchical data structures. Each row can also contain an additional nested sub-DataTable (commonly referred to as a 'subtable').

Both DataTables and DataTable rows can hold metadata. DataTable metadata is information regarding all the data, such as the site or period that the data is for. Row metadata is information regarding that row, such as a browser logo or website URL.

Finally, all DataTables contain a special summary row. This row, if it exists, is always at the end of the DataTable.

Populating DataTables

Data can be added to DataTables in three different ways. You can either:

  1. create rows one by one and add them through addRow() then truncate if desired,
  2. create an array of DataTable\Row instances or an array of arrays and add them using addRowsFromArray() or addRowsFromSimpleArray() then truncate if desired,
  3. or set the maximum number of allowed rows (with setMaximumAllowedRows()) and add rows one by one.

If you want to eventually truncate your data (standard practice for all Matomo plugins), the third method is the most memory efficient. It is, unfortunately, not always possible to use since it requires that the data be sorted before adding.

Manipulating DataTables

There are two ways to manipulate a DataTable. You can either:

  1. manually iterate through each row and manipulate the data,
  2. or you can use predefined filters.

A filter is a class that has a 'filter' method which will manipulate a DataTable in some way. There are several predefined Filters that allow you to do common things, such as,

  • add a new column to each row,
  • add new metadata to each row,
  • modify an existing column value for each row,
  • sort an entire DataTable,
  • and more.

Using these filters instead of writing your own code will increase code clarity and reduce code redundancy. Additionally, filters have the advantage that they can be applied to DataTable\Map instances. So you can visit every DataTable in a Map without having to write a recursive visiting function.

All predefined filters exist in the Piwik\DataTable\BaseFilter namespace.

Note: For convenience, anonymous functions can be used as DataTable filters.

Applying Filters

Filters can be applied now (via filter()), or they can be applied later (via queueFilter()).

Filters that sort rows or manipulate the number of rows should be applied right away. Non-essential, presentation filters should be queued.

Examples

Populating a DataTable

// adding one row at a time
$dataTable = new DataTable();
$dataTable->addRow(new Row(array(
    Row::COLUMNS => array('label' => 'thing1', 'nb_visits' => 1, 'nb_actions' => 1),
    Row::METADATA => array('url' => 'http://thing1.com')
)));
$dataTable->addRow(new Row(array(
    Row::COLUMNS => array('label' => 'thing2', 'nb_visits' => 2, 'nb_actions' => 2),
    Row::METADATA => array('url' => 'http://thing2.com')
)));

// using an array of rows
$dataTable = new DataTable();
$dataTable->addRowsFromArray(array(
    array(
        Row::COLUMNS => array('label' => 'thing1', 'nb_visits' => 1, 'nb_actions' => 1),
        Row::METADATA => array('url' => 'http://thing1.com')
    ),
    array(
        Row::COLUMNS => array('label' => 'thing2', 'nb_visits' => 2, 'nb_actions' => 2),
        Row::METADATA => array('url' => 'http://thing2.com')
    )
));

// using a "simple" array
$dataTable->addRowsFromSimpleArray(array(
    array('label' => 'thing1', 'nb_visits' => 1, 'nb_actions' => 1),
    array('label' => 'thing2', 'nb_visits' => 2, 'nb_actions' => 2)
));

Getting & setting metadata

$dataTable = \Piwik\Plugins\Referrers\API::getInstance()->getSearchEngines($idSite = 1, $period = 'day', $date = '2007-07-24');
$oldPeriod = $dataTable->metadata['period'];
$dataTable->metadata['period'] = Period\Factory::build('week', Date::factory('2013-10-18'));

Serializing & unserializing

$maxRowsInTable = Config::getInstance()->General['datatable_archiving_maximum_rows_standard'];j

$dataTable = // ... build by aggregating visits ...
$serializedData = $dataTable->getSerialized($maxRowsInTable, $maxRowsInSubtable = $maxRowsInTable,
                                            $columnToSortBy = Metrics::INDEX_NB_VISITS);

$serializedDataTable = $serializedData[0];
$serailizedSubTable = $serializedData[$idSubtable];

Filtering for an API method

public function getMyReport($idSite, $period, $date, $segment = false, $expanded = false)
{
    $dataTable = Archive::createDataTableFromArchive('MyPlugin_MyReport', $idSite, $period, $date, $segment, $expanded);
    $dataTable->filter('Sort', array(Metrics::INDEX_NB_VISITS, 'desc', $naturalSort = false, $expanded));
    $dataTable->queueFilter('ColumnCallbackAddMetadata', array('label', 'url', __NAMESPACE__ . '\getUrlFromLabelForMyReport'));
    return $dataTable;
}

Constants

This class defines the following constants:

COLUMN_AGGREGATION_OPS_METADATA_NAME

This metadata value must be an array that maps column names with valid operations. Valid aggregation operations are:

  • 'skip': do nothing
  • 'max': does max($column1, $column2)
  • 'min': does min($column1, $column2)
  • 'sum': does $column1 + $column2

See addDataTable() and Row::sumRow() for more information.

ID_ARCHIVED_METADATA_ROW

This allows us to save datatable metadata in archive data.

EXTRA_PROCESSED_METRICS_METADATA_NAME

These metrics will be added in addition to the ones specified in the table's associated Report class.

Methods

The class defines the following methods:

__construct()

Constructor. Creates an empty DataTable.

Signature

__destruct()

Destructor. Makes sure DataTable memory will be cleaned up.

Signature

  • It does not return anything or a mixed result.

enableRecursiveSort()

Enables recursive sorting. If this method is called sort() will also sort all subtables.

Signature

    • $parameters (array) — Array of extra parameters to pass to the filter.
  • It does not return anything or a mixed result.

multiFilter()

Invokes $filter with this table and every table in $otherTables. The result of $filter() is returned.

This method is used to iterate over multiple DataTable\Map's concurrently.

See Map::multiFilter() for more information.

Signature

queueFilterSubtables()

Adds a filter and a list of parameters to the list of queued filters of all subtables. These filters will be executed when applyQueuedFilters() is called.

Filters that prettify the column values or don't need the full set of rows should be queued. This way they will be run after the table is truncated which will result in better performance.

If the subtables for this table are loaded, they will be summed as well.

Rows are summed together by summing individual columns. By default columns are summed by adding one column value to another. Some columns cannot be aggregated this way. In these cases, the COLUMN_AGGREGATION_OPS_METADATA_NAME metadata can be used to specify a different type of operation.
