Chunk Size (Magic xpa 4.x)
The chunk size task property determines how many records are fetched from the server to the client cache. Setting the correct chunk size reduces redundant data transmission and server interaction.
In most cases of simple line mode view of the data, the required chunk size may vary according to the size of each record and the estimated amount of records that will be scrolled through by the end-user. If the task data view is designed to be scrolled through frequently and through a large amount of records, it is preferable to increase the chunk size. On the other hand, if the record size is large, it is preferable to reduce the chunk size, which reduces the amount of data transmitted for each data chunk. When no expression is defined for the property of such a task, the default chunk size is 30. The maximum size is 999, a larger value will be considered as 999.
A task that has no main source does not require fetching a set amount of records. It is sufficient to provide only one record, the virtual record. Such a task should have its chunk size property set to 1. If you set the chunk size to be greater than 1, it brings When no expression is defined for the property of such a task, the default chunk size is 1.
