=== {transform-cap} resources
|
|
|
|
{transform-cap} resources relate to the <<data-frame-apis>>.
|
|
|
|
For more information, see
|
|
{stack-ov}/ecommerce-dataframes.html[Transforming your data with {dataframes}].

==== {api-definitions-title}
|
|
|
|
`description`::
|
|
(string) A description of the {transform}.
|
|
|
|
`dest`::
|
|
(object) The destination for the {transform}. See
|
|
<<data-frame-transform-dest>>.
|
|
|
|
`frequency`::
|
|
(time units) The interval between checks for changes in the source indices
|
|
when the {transform} is running continuously. Also determines the
|
|
retry interval in the event of transient failures while the {transform} is
|
|
searching or indexing. The minimum value is `1s` and the maximum is `1h`. The
|
|
default value is `1m`.
|
|
|
|
`id`::
|
|
(string) A unique identifier for the {transform}.
|
|
|
|
`pivot`::
|
|
(object) The method for transforming the data. See
|
|
<<data-frame-transform-pivot>>.
|
|
|
|
`source`::
|
|
(object) The source of the data for the {transform}. See
|
|
<<data-frame-transform-source>>.
|
|
|
|
[[data-frame-transform-dest]]
|
|
==== Dest objects
|
|
|
|
{transform-cap} resources contain `dest` objects. For example, when
|
|
you create a {transform}, you must define its destination.

|
|
|
|
`index`::
|
|
(string) The _destination index_ for the {transform}.
|
|
|
|
`pipeline`::
|
|
(string) The unique identifier for a <<pipeline,pipeline>>.

|
|
==== Source objects
|
|
|
|
{transform-cap} resources contain `source` objects. For example, when
|
|
you create a {transform}, you must define its source.

|
===== {api-definitions-title}
|
|
|
|
`index`::
|
|
(string or array) The _source indices_ for the {transform}. It can
|
|
be a single index, an index pattern (for example, `"myindex*"`), or an array
|
|
of indices (for example, `["index1", "index2"]`).
|
|
|
|
`query`::
|
|
(object) A query clause that retrieves a subset of data from the source index.
|
|
See <<query-dsl>>.

|
|
|
[[data-frame-transform-pivot]]
|
|
==== Pivot objects
|
|
|
|
{transform-cap} resources contain `pivot` objects, which define the
|
|
pivot function `group by` fields and the aggregation to reduce the data.

|
`aggregations` or `aggs`::
|
|
(object) Defines how to aggregate the grouped data. The following composite
|
|
aggregations are supported:

per pivot. The following groupings are supported:

`max_page_search_size`::
|
|
(integer) Defines the initial page size to use for the composite aggregation

for each checkpoint. If circuit breaker exceptions occur, the page size is
|
|
dynamically adjusted to a lower value. The minimum value is `10` and the
|
|
maximum is `10,000`. The default value is `500`.
