4.  def alignInsertAssignments(attrs: Seq[Attribute], assignments: Seq[Assignment]): Seq[Assignment]

   Aligns insert assignments to match table columns.

   Aligns insert assignments to match table columns.

   This method processes and reorders given assignments so that each target column gets an expression it should be set to. There must be exactly one assignment for each top-level attribute and its value must be compatible.

   Insert assignments cannot refer to nested columns.

   attrs

   table attributes

   assignments

   insert assignments to align

   returns

   aligned insert assignments that match table attributes

5.  def alignUpdateAssignments(attrs: Seq[Attribute], assignments: Seq[Assignment]): Seq[Assignment]

   Aligns update assignments to match table columns.

   Aligns update assignments to match table columns.

   This method processes and reorders given assignments so that each target column gets an expression it should be set to. If a column does not have a matching assignment, it will be set to its current value. For example, if one passes table attributes c1, c2 and an assignment c2 = 1, this method will return c1 = c1, c2 = 1. This allows Spark to construct an updated version of a row.

   This method also handles updates to nested columns. If there is an assignment to a particular nested field, this method will construct a new struct with one field updated preserving other fields that have not been modified. For example, if one passes table attributes c1, c2 where c2 is a struct with fields n1 and n2 and an assignment c2.n2 = 1, this method will return c1 = c1, c2 = struct(c2.n1, 1).

6.  def aligned(attrs: Seq[Attribute], assignments: Seq[Assignment]): Boolean

   Checks whether assignments are aligned and compatible with table columns.

   Checks whether assignments are aligned and compatible with table columns.
