auto_unload
option in
recommend
mode. See
Section 2.7.3, “HeatWave Autopilot Advisor Syntax”.
Use the exclude_list
option to define a
list of schemas and tables to exclude from Unload Advisor.
Use the last_queried_hours
option to only
recommend unloading tables that were not queried during this
past number of hours. The default is 24
hours.
Set memory_gain_ascending
to
true
to rank the unload table suggestions
in ascending order based on the table size. The default is
false
.
Use the limit_tables
option to limit the
number of unload table suggestions, based on the order
imposed by memory_gain_ascending
. The
default is 10
.
