spEnrichedFilterContext
spEnrichedFilterContext
: Specific to Snowplow data. Filters messages based on a regex match against a field in a context.
This transformation is for use on fileds from contexts.
Note that if the same context is present in the data more than once, one instance of a match is enough for the regex condition to be considered a match โ and the message to be kept.
The full parsed context name must be provided, in camel case, in the format returned by the Snowplow analytics SDK: contexts_{vendor}_{name}_{major version}
โ for example contexts_nl_basjes_yauaa_context_1
.
The path to the field to be matched must then be provided as a jsonpath (dot notation and square braces only) โ for example test1.test2[0].test3
.
Filters can be used in one of two ways, which is determined by the filter_action
option. filter_action
determines the behavior of the app when the regex provided evaluates to true
. If it's set to "keep"
, the app will complete the remaining transformations and send the message to the destination (unless a subsequent filter determines otherwise). If it's set to "drop"
, the message will be acked and discarded, without continuing to the next transformation or target.
The below example keeps messages which contain prod
in the environment
field of the contexts_com_acme_env_context_1
context. Note that the contexts_com_acme_env_context_1
context is attached more than once, if any of the values at dev
don't match environment
, the message will be kept.
