You can then use this expansion + # just like any other: + # + # update reply { + # Filter-Id := "%{redundant_sql: ... }" + # } + # + # In this example, the expansion is done via module "sql1", + # and if that expansion fails, using module "sql2". + # + # For best results, configure the "pool" subsection of the + # module so that "retry_delay" is non-zero.
