lazy update
Method for creating or updating non-unique secondary table keys in
internal tables. Non-unique
secondary tables keys are not updated straight after insert operations using
INSERT or APPEND,
or after a block operation that fills the whole table body at once, or after an operation using MODIFY, or using
field symbols or
data references. The keys are updated the next time they are used explicitly. See also
direct update and delayed update.
