### Properties Added
```javascript

For capacity-enabled buckets, contains the following data:
```javascript

# Delimiter
The Delimiter class handles raw listings from the database with an
optional delimiter, and fills in a curated listing with "Contents" and
"CommonPrefixes" as a result.
## Expected Behavior
- only lists keys belonging to the given **prefix** (if provided)
- groups listed keys that have a common prefix ending with a delimiter
inside CommonPrefixes
- can take a **marker** or **continuationToken** to list from a specific key
- can take a **maxKeys** parameter to limit how many keys can be returned
## State Chart
- States with grey background are *Idle* states, which are waiting for
a new listing key
- States with blue background are *Processing* states, which are
actively processing a new listing key passed by the filter()
function

# DelimiterMaster
The DelimiterMaster class handles raw listings from the database of a
versioned or non-versioned bucket with an optional delimiter, and
fills in a curated listing with "Contents" and "CommonPrefixes" as a
result.
## Expected Behavior
- only lists latest versions of versioned buckets
- only lists keys belonging to the given **prefix** (if provided)
- does not list latest versions that are delete markers
- groups listed keys that have a common prefix ending with a delimiter
inside CommonPrefixes
- can take a **marker** or **continuationToken** to list from a specific key
- can take a **maxKeys** parameter to limit how many keys can be returned
- reconciles internal PHD keys with the next version (those are
created when a specific version that is the latest version is
deleted)
- skips internal keys like replay keys
## State Chart
- States with grey background are *Idle* states, which are waiting for
a new listing key
- States with blue background are *Processing* states, which are
actively processing a new listing key passed by the filter()
function
### Bucket Vformat=v0
![DelimiterMaster State Chart for v0 format](./pics/delimiterMasterV0StateChart.svg)
### Bucket Vformat=v1
For buckets in versioning key format **v1**, the algorithm used is the
one from [Delimiter](delimiter.md).

# DelimiterVersions
The DelimiterVersions class handles raw listings from the database of a
versioned or non-versioned bucket with an optional delimiter, and
fills in a curated listing with "Versions" and "CommonPrefixes" as a
result.
## Expected Behavior
- lists individual distinct versions of versioned buckets
- only lists keys belonging to the given **prefix** (if provided)
- groups listed keys that have a common prefix ending with a delimiter
inside CommonPrefixes
- can take a **keyMarker** and optionally a **versionIdMarker** to
list from a specific key or version
- can take a **maxKeys** parameter to limit how many keys can be returned
- skips internal keys like replay keys
## State Chart
- States with grey background are *Idle* states, which are waiting for
a new listing key

/**
* Cache of listing "gaps" i.e. ranges of keys that can be skipped
* over during listing (because they only contain delete markers as
* latest versions).
*
* Typically, a single GapCache instance would be attached to a raft session.
*
* The API usage is as follows:
*
* - Initialize a GapCache instance by calling start() (this starts an internal timer)
*
* - Insert a gap or update an existing one via setGap()
*
* - Lookup existing gaps via lookupGap()
*
* - Invalidate gaps that overlap a specific set of keys via removeOverlappingGaps()
*
* - Shut down a GapCache instance by calling stop() (this stops the internal timer)
*
* Gaps inserted via setGap() are not exposed immediately to lookupGap(), but only:
*
* - after a certain delay always larger than 'exposureDelayMs' and usually shorter
* than twice this value (but might be slightly longer in rare cases)
*
* - and only if they haven't been invalidated by a recent call to removeOverlappingGaps()
*
* This ensures atomicity between gap creation and invalidation from updates under
* the condition that a gap is created from first key to last key within the time defined
* by 'exposureDelayMs'.
*
* The implementation is based on two extra temporary "update sets" on top of the main
* exposed gap set, one called "staging" and the other "frozen", each containing a
* temporary updated gap set and a list of updated keys to invalidate gaps with (coming
* from calls to removeOverlappingGaps()). Every "exposureDelayMs" milliseconds, the frozen
* gaps are invalidated by all key updates coming from either of the "staging" or "frozen"
* update set, then merged into the exposed gaps set, after which the staging updates become
* the frozen updates and won't receive any new gap until the next cycle.

/**
* Remote procedure calls support between cluster workers.
*
* When using the cluster module, new processes are forked and are
* dispatched workloads, usually HTTP requests. The ClusterRPC module
* implements a RPC system to send commands to all cluster worker
* processes at once from any particular worker, and retrieve their
* individual command results, like a distributed map operation.
*
* The existing nodejs cluster IPC channel is setup from the primary
* to each worker, but not between workers, so there has to be a hop
* by the primary.
*
* How a command is treated:
*
* - a worker sends a command message to the primary
*
* - the primary then forwards that command to each existing worker
* (including the requestor)
*
* - each worker then executes the command and returns a result or an
* error
*
* - the primary gathers all workers results into an array
*
* - finally, the primary dispatches the results array to the original
* requesting worker
*
*
* Limitations:
*
* - The command payload must be serializable, which means that:
* - it should not contain circular references
* - it should be of a reasonable size to be sent in a single RPC message
*
* - The "toWorkers" parameter of value "*" targets the set of workers
* that are available at the time the command is dispatched. Any new
* worker spawned after the command has been dispatched for
* processing, but before the command completes, don't execute
* the command and hence are not part of the results array.
*
*
* To set it up:
*
* - On the primary:
* if (cluster.isPrimary) {
* setupRPCPrimary();
* }
*
* - On the workers:
* if (!cluster.isPrimary) {
* setupRPCWorker({
* handler1: (payload: object, uids: string, callback: HandlerCallback) => void,
* handler2: ...
* });
* }
* Handler functions will be passed the command payload, request
* serialized uids, and must call the callback when the worker is done
* processing the command:
* callback(error: Error | null | undefined, result?: any)
*
* When this setup is done, any worker can start sending commands by calling
* the async function sendWorkerCommand().

To avoid race conditions we always (try to) generate a new UUID and we
condition the insertion to the non-existence of the document.
#### Oplog Events
The oplog (operations log) is a special capped collection that keeps a
rolling record of all operations that modify the data stored in the database.
The oplog is read and used by multiple backbeat extensions such as replication
and bucket notification to react to database changes.
oplog events have different types such as insertion, update and deletion.
Within an oplog event we find the changes that occured at object level or
collection level.
At object level if an object was inserted for example we'll find all of the object's
data in the event. Update events contain the change that occured to an object, and
delete events don't contain anything (only the object's _id).
To keep the latest object's metadata before it got deleted in the oplog, we update
the full object setting a deletion flag before deleting the object. This adds an
update event containing all of the object's metadata.
Note: updating the object with itself without change creates a no-op event that gets
ignored.
**Special Cases:**
When deleting the last version of an object in a versioned bucket, the master object
goes into a PHD state (temporary non updated state) that gets resolved later. There
is one case where a master can be non existent, it's where the last version is a
delete marker. In this case the created PHD master is empty only containing the
isPHD flag and the versionId.
When versioning is enabled in a bucket, only version events should be processed as
they already contain all of the information needed.
In non versioned buckets, master object events are the ones to be processed.
In versioning suspended buckets, both master and version events should be processed,
as the master object itself is considered a null version. No special case is present
here as the master object is always present.
