materialize_node: Create a materialize node.

In rquery: Relational Query Generator for Data Manipulation at Scale

Create a materialize node.

Description

Write results into a specified table. Result is transient, lives only for the duration of the pipeline calculation. This node is only used to break up or un-nest calculations, not for value sharing or re-use.

Usage

materialize_node(
  source,
  table_name = (wrapr::mk_tmp_name_source("rquerymn"))(),
  ...,
  qualifiers = NULL
)

Arguments

source	source to work from (relop node)
table_name	character, name of caching table
...	not used, force later argument to bind by name
qualifiers	optional named ordered vector of strings carrying additional db hierarchy terms, such as schema.

Details

Note this node can not be used in multiple paths in the same rel_op tree as it re-uses table names and re-computes each time called.

Value

relop materialize_node
