# 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

### 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

* 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().
