batchSize
You can use batchsize in both GET and POST calls for different purposes.
GET calls. When you use
batchsize, you define the number of records to include for a data object or a conceptual object in the
OneData response. Use any positive integer value for
batchsize, for example,
batchSize=25. When used with
pageNum in a GET call, you control the number of records on each page of the response. For more details on how to use
batchsize and
pageNum together, see
pageNum.
POST calls. batchsize indicates the number of records for
OneData to process as a batch. The default value is 100, and is specified in the property
onedata.interchangeexecution.batchsize in the onedata.properties file. For more details on
onedata.interchangeexecution.batchsize, see
Administering webMethods OneData.
Use this parameter only in XML REST APIs. JSON payload handles a small set of records, which would generally be part of a single batch. Therefore, OneData ignores this parameter during JSON payload processing. Additionally, during JSON in-memory processing, OneData does not support concurrent processing.
Tip: The batch size you choose must depend on the amount of memory available for processing on the server. Conceptual objects use more memory. You should decrease batchSize for conceptual objects because they use more memory and increase it for data objects. For large conceptual objects, try configuring different values for batchSize to find the size that offers the best response time without generating an OutOfMemoryException error.
