# Context
Rewards payout is processed today in a single block and limited to
`MaxNominatorRewardedPerValidator`. This number is currently 512 on both
Kusama and Polkadot.
This PR tries to scale the nominators payout to an unlimited count in a
multi-block fashion. Exposures are stored in pages, with each page
capped to a certain number (`MaxExposurePageSize`). Starting out, this
number would be the same as `MaxNominatorRewardedPerValidator`, but
eventually, this number can be lowered through new runtime upgrades to
limit the rewardeable nominators per dispatched call instruction.
The changes in the PR are backward compatible.
## How payouts would work like after this change
Staking exposes two calls, 1) the existing `payout_stakers` and 2)
`payout_stakers_by_page`.
### payout_stakers
This remains backward compatible with no signature change. If for a
given era a validator has multiple pages, they can call `payout_stakers`
multiple times. The pages are executed in an ascending sequence and the
runtime takes care of preventing double claims.
### payout_stakers_by_page
Very similar to `payout_stakers` but also accepts an extra param
`page_index`. An account can choose to payout rewards only for an
explicitly passed `page_index`.
**Lets look at an example scenario**
Given an active validator on Kusama had 1100 nominators,
`MaxExposurePageSize` set to 512 for Era e. In order to pay out rewards
to all nominators, the caller would need to call `payout_stakers` 3
times.
- `payout_stakers(origin, stash, e)` => will pay the first 512
nominators.
- `payout_stakers(origin, stash, e)` => will pay the second set of 512
nominators.
- `payout_stakers(origin, stash, e)` => will pay the last set of 76
nominators.
...
- `payout_stakers(origin, stash, e)` => calling it the 4th time would
return an error `InvalidPage`.
The above calls can also be replaced by `payout_stakers_by_page` and
passing a `page_index` explicitly.
## Commission note
Validator commission is paid out in chunks across all the pages where
each commission chunk is proportional to the total stake of the current
page. This implies higher the total stake of a page, higher will be the
commission. If all the pages of a validator's single era are paid out,
the sum of commission paid to the validator across all pages should be
equal to what the commission would have been if we had a non-paged
exposure.
### Migration Note
Strictly speaking, we did not need to bump our storage version since
there is no migration of storage in this PR. But it is still useful to
mark a storage upgrade for the following reasons:
- New storage items are introduced in this PR while some older storage
items are deprecated.
- For the next `HistoryDepth` eras, the exposure would be incrementally
migrated to its corresponding paged storage item.
- Runtimes using staking pallet would strictly need to wait at least
`HistoryDepth` eras with current upgraded version (14) for the migration
to complete. At some era `E` such that `E >
era_at_which_V14_gets_into_effect + HistoryDepth`, we will upgrade to
version X which will remove the deprecated storage items.
In other words, it is a strict requirement that E<sub>x</sub> -
E<sub>14</sub> > `HistoryDepth`, where
E<sub>x</sub> = Era at which deprecated storages are removed from
runtime,
E<sub>14</sub> = Era at which runtime is upgraded to version 14.
- For Polkadot and Kusama, there is a [tracker
ticket](https://github.com/paritytech/polkadot-sdk/issues/433) to clean
up the deprecated storage items.
### Storage Changes
#### Added
- ErasStakersOverview
- ClaimedRewards
- ErasStakersPaged
#### Deprecated
The following can be cleaned up after 84 eras which is tracked
[here](https://github.com/paritytech/polkadot-sdk/issues/433).
- ErasStakers.
- ErasStakersClipped.
- StakingLedger.claimed_rewards, renamed to
StakingLedger.legacy_claimed_rewards.
### Config Changes
- Renamed MaxNominatorRewardedPerValidator to MaxExposurePageSize.
### TODO
- [x] Tracker ticket for cleaning up the old code after 84 eras.
- [x] Add companion.
- [x] Redo benchmarks before merge.
- [x] Add Changelog for pallet_staking.
- [x] Pallet should be configurable to enable/disable paged rewards.
- [x] Commission payouts are distributed across pages.
- [x] Review documentation thoroughly.
- [x] Rename `MaxNominatorRewardedPerValidator` ->
`MaxExposurePageSize`.
- [x] NMap for `ErasStakersPaged`.
- [x] Deprecate ErasStakers.
- [x] Integrity tests.

## Breaking Changes
This PR introduces a new item to `pallet_balances::Config`:
```diff
trait Config {
++ type RuntimeFreezeReasons;
}
```
This value is only used to check it against `type MaxFreeze`. A similar
check has been added for `MaxHolds` against `RuntimeHoldReasons`, which
is already given to `pallet_balances`.
In all contexts, you should pass the real `RuntimeFreezeReasons`
generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing
`()` would also work, but it would imply that the runtime uses no
freezes at all.

* HoldReason: Improve usage
`HoldReason` was switched recently to use the `composite_enum` attribute that will merge the enums
from all pallets in the runtime to `RuntimeHoldReason`. `pallet-nis` was still requiring that the
variant was passed as constant to call `hold`. The proper implementation is to use the `HoldReason`
from inside the pallet directly when calling `hold`. This is done by adding a `RuntimeHoldReason` as
type to the `Config` trait and requiring that `Currency` is using the same reason. Besides that the
pr changes the name `HoldIdentifier` in `pallet_balances::Config` to `RuntimeHoldReason`.

* pallet-offences-benchmarking: Box events in verify
Events in frame are represented by an enum in the pallet and the runtime. The size of an enum in
Rust depends on the size of biggest variant. This means we always need to allocate memory for the
biggest variant when allocating memory for an event. The offences benchmarking is verifying the
benchmarking results by checking the events. To check the events it is generating all the expected
events. With the recent changes in Polkadot the events are too big and lead to issues when running
this verify functions. The solution is to box each event, as the vector holding all the events will
then only need to hold fat pointers * expected events, instead of size_of(event) * expected events.
This issue isn't a problem in production, as we never read the events on chain. When we are reading
the events, it is done in an offchain context and they are only decoded one by one.
Besides that this also enables the benchmarking verification for everyone running these benchmarks.
