Field Type Description Default Value Required

Initial Buffer Size

Number

Initial amount of memory to allocate to the data stream. If the streamed data exceeds this value, the buffer expands by Buffer Size Increment, with an upper limit of Max In Memory Size value.

Buffer Size Increment

Number

This is by how much the buffer size expands if it exceeds its initial size. Setting a value of zero or lower means that the buffer should not expand, meaning that a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised when the buffer gets full.

Max Buffer Size

Number

Maximum size of the buffer. If the buffer size exceeds this value, Mule raises a STREAM_MAXIMUM_SIZE_EXCEEDED error. A value of less than or equal to 0 means no limit.

Unit for the Initial Buffer Size, Buffer Size Increment, and Buffer Unit fields.

Repeatable File Store Stream

Configures the repeatable file-store streaming strategy by which Mule keeps a portion of the stream content in memory. If the stream content is larger than the configured buffer size, Mule backs up the buffer’s content to disk and then clears the memory.

Field Type Description Default Value Required

In Memory Size

Number

Maximum amount of memory that the stream can use for data. If the amount of memory exceeds this value, Mule buffers the content to disk. To optimize performance:

  • Configure a larger buffer size to avoid the number of times Mule needs to write the buffer on disk. This increases performance, but it also limits the number of concurrent requests your application can process, because it requires additional memory.

  • Configure a smaller buffer size to decrease memory load at the expense of response time.

Buffer Unit

Enumeration, one of:

  • BYTE

  • KB

  • MB

  • GB

Unit for the In Memory Size field.

Use Secure Hash

Boolean

If true, Mule uses a secure hash algorithm to identify a redelivered message.

Message Digest Algorithm

Secure hashing algorithm to use if the Use Secure Hash field is true. If the payload of the message is a Java object, Mule ignores this value and returns the value that the payload’s hashCode() returned.

Id Expression

String

One or more expressions that determine when a message was redelivered. You can set this property only if the Use Secure Hash field is false.

Object Store
