MBrace Types in Overview

MBrace.Core

Cloud Type
`Cloud<T>`	Represents a distributed cloud computation
`LocalCloud<T>`	Represents a machine-constrained cloud computation. The computation runs to completion as a locally executing in-memory computation. The computation may access concurrent shared memory and unserializable resources.

Cloud Type	Underlying	Gives	Persist	Caching	Partition	Indexed	Mutable	Description
`CloudFile`	Blob store	byte[]/lines/text	yes	no	via seek	via seek	no	Files named by string
`CloudValue<T>`	`CloudFile` + deserializer for `T`	`T`	yes	on default	single file	no	no	A distributed value that has been cached by the MBrace runtime
`CloudArray<T>`	`CloudFile` + deserializer for `T`	`T[]`	yes	no	no	no	no	A distributed, immutable array that has been cached by the MBrace runtime
`CloudAtom<T>`	Table store	`T`	no	no	no	no	yes	A distributed. atomically updatable value reference
`CloudDictionary<T>`	Table store	`string -> T`	yes	no	yes, one per key	yes	yes	A distributed key-value collection
`CloudQueue<T>`	Service Bus	`T` values	N/A	N/A	no	N/A	yes	A distributed queue

Cloud Type	Description	Mechanism
`CloudFlow<T>`	Represents a distributed stream of values	The stream iterated via a distributable evaluators that transform the ultimate input using a multi-core, distributed pipeline

CloudFlow Producer	Source	Partition	Description
`CloudFlow.OfArray`	Serialized array	divide by #workers + #cores
`CloudFlow.OfCloudArrays`	`CloudArray<T>`	by #arrays
`CloudFlow.OfCloudCollection`	`ICloadCollection<T>`	divide by #workers + #cores
`CloudFlow.OfCloudDirectory`	Cloud file system	by file (?)	Constructs a CloudFlow from all files in provided directory using the given reader
`CloudFlow.OfCloudDirectoryByLine`	Cloud file system	by file + chunks (?)	Constructs a text CloudFlow by line from all files in supplied CloudDirectory
`CloudFlow.OfCloudFileByLine`	Cloud file system	by chunks (?)	Constructs a CloudFlow of lines from a single large text file.
`CloudFlow.OfCloudFilesByLine`	Cloud file system	by files + chunks (?)	Constructs a CloudFlow of lines from a collection of text files.
`CloudFlow.OfCloudFiles`	Cloud file system	by files
`CloudFlow.OfCloudQueue`	Cloud queue	by provided count	Creates a CloudFlow from the ReceivePort of a CloudQueue
`CloudFlow.OfHttpFileByLine`	Network	by #workers + #cores depending on request	Constructs a CloudFlow of lines from a single HTTP text file.
`CloudFlow.OfHttpFilesByLine`	Network	by #requests + #workers + #cores depending on request	Constructs a CloudFlow of lines from a collection of HTTP text files.
`CloudFlow.OfSeqs`	Serialized IEnumerables	by #collections	Creates a CloudFlow instance from a finite collection of serializable enumerations

CloudFlow Sink	Writes To	Partitioned Write	Description
`CloudFlow.toArray`	Serialized array	yes	Creates an array from the given CloudFlow.
`CloudFlow.toCloudQueue`	Cloud queue	yes (?)	Sends the values of CloudFlow to the SendPort of a CloudQueue
`CloudFlow.toTextCloudFiles`	Cloud file system	yes	Creates line separated CloudFiles from the given CloudFlow of strings
`CloudFlow.cache`	Cloud temp storage on workers	yes	Creates a PersistedCloudFlow from the given CloudFlow
`CloudFlow.persist`	Cloud bloc storage or temp storage on workers	yes (?)	Creates a PersistedCloudFlow from the given CloudFlow, with its partitions cached to a specified storage level.
