Advanced Properties

Advanced Properties

The Developer tool displays the advanced properties for HBase targets in the
Advanced
view.
The following table describes the advanced properties that you can configure for an HBase data object in a streaming mapping:
Property
Description
Operation Type
The type of data object operation.
This is a read-only property.
Date Time Format
Format of the columns of the date data type.
Specify the date and time formats by using any of the Java date and time pattern strings.
Auto Flush
Optional. Indicates whether you want to enable Auto Flush.
You can set auto flush to the following values:
  • Enable
    Auto Flush
    to set the value to true. The Data Integration Service runs each Put operation immediately as it receives them. The service does not buffer or delay the Put operations. Operations are not retried on failure. When you enable auto flush, the operations are slow as you cannot run operations in bulk. However, you do not lose data as the Data Integration Service writes the data immediately.
  • Disable
    Auto Flush
    to set the auto flush value to false. When you disable auto flush, the Data Integration Service accepts multiple Put operations before making a remote procedure call to perform the write operations. If the Data integration Service stops working before it flushes any pending data writes to HBase, that data is lost. Disable auto flush if you need to optimize performance.
Default is disabled.
