Repeatable in Memory Stream

Field Type Description Default Value Required

Initial Buffer Size

Number

The amount of memory that is allocated to consume the stream and provide random access to it. If the stream contains more data than buffer capacity, then it is expanded according to the bufferSizeIncrement attribute, with an upper limit of maxInMemorySize.

Buffer Size Increment

Number

How much buffer size expands if it exceeds its initial size. A value of zero or lower specifies that the buffer doesn’t expand. When the buffer is full, a STREAM_MAXIMUM_SIZE_EXCEEDED error occurs.

Max Buffer Size

Number

The maximum amount of memory used. If more is used, a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised. A value lower or equal to zero means no limit.

Buffer Unit

Enumeration, one of:

  • BYTE

  • KB

  • MB

  • GB

These attributes are expressed in this unit.

Repeatable File Store Stream

Field Type Description Default Value Required

In Memory Size

Number

Defines the maximum memory that the stream uses to keep data in memory. If it consumes more, the stream buffers the content on disk.

Buffer Unit

Enumeration, one of:

  • BYTE

  • KB

  • MB

  • GB

The unit for expressing maxInMemorySize

Redelivery Policy

Field Type Description Default Value Required

Max Redelivery Count

Number

The maximum number of times a message can be redelivered and processed unsuccessfully before triggering a "Process failed" message.

Message Digest Algorithm

String

The secure hashing algorithm to use. If not set, the default is SHA-256.

Message Identifier

The strategy to use to identify the messages

Object Store

ObjectStore

The object store where the redelivery counter for each message is stored

Redelivery Policy Message Identifier

Field Type Description Default Value Required

Use Secure Hash

Boolean

Whether to use a secure hash algorithm to identify a redelivered message

Id Expression

String

Expressions to use to determine when a message has been redelivered. You can only set this property if useSecureHash is false.
