Example
The data read from source is a table like this:
name | age | card |
---|---|---|
Joy Ding | 20 | 123 |
May Ding | 20 | 123 |
Kin Dom | 20 | 123 |
Joy Dom | 20 | 123 |
we want to keep the field named name
, card
, we can add a Filter
Transform like below:
transform {
Filter {
plugin_input = "fake"
plugin_output = "fake1"
include_fields = [name, card]
}
}
Or we can delete the field named age
by adding a Filter
Transform with exclude_fields
field set like below:
transform {
Filter {
plugin_input = "fake"
plugin_output = "fake1"
exclude_fields = [age]
}
}
It is useful when you want to delete a small number of fields from a large table with tons of fields.
Then the data in result table fake1
will like this
name | card |
---|---|
Joy Ding | 123 |
May Ding | 123 |
Kin Dom | 123 |
Joy Dom | 123 |
