)
Expand description
Continue the migration for the given limits
.
The dispatch origin of this call can be any signed account.
This transaction has NO MONETARY INCENTIVES. calling it will not reward anyone. Albeit, Upon successful execution, the transaction fee is returned.
The (potentially over-estimated) of the byte length of all the data read must be
provided for up-front fee-payment and weighing. In essence, the caller is guaranteeing
that executing the current MigrationTask
with the given limits
will not exceed
real_size_upper
bytes of read data.
The witness_task
is merely a helper to prevent the caller from being slashed or
generally trigger a migration that they do not intend. This parameter is just a message
from caller, saying that they believed witness_task
was the last state of the
migration, and they only wish for their transaction to do anything, if this assumption
holds. In case witness_task
does not match, the transaction fails.
Based on the documentation of MigrationTask::migrate_until_exhaustion
, the
recommended way of doing this is to pass a limit
that only bounds count
, as the
size
limit can always be overwritten.
