You can then delete the fields you don't want to retrieveДЄll fields of this step support metadata injection. Lookups are done via a binary tree search.)ДЄutomatically fills in the names of all the available fields on the source side (A) you can then delete all the fields you don't want to use for lookup.ДЄutomatically inserts the names of all the available fields on the lookup side (B). (Technical background: the lookup data is put into a tuple and stored in a sorted list. Cannot be combined with the 'Key and value are exactly one integer field' option. Note: Works only when 'Preserve memory' is checked. It just takes a hashcode of the long.)Д®nable to store values using a sorted list this provides better memory usage when working with data sets containing wide row. (Technical background: The lookup data is stored in a custom storage object that is similar to the byte array hashmap, but it doesn't have to convert to raw bytes. Let IT Central Station and our comparison database help you with your research. Cannot be combined with the 'Use sorted list' option. Delphix vs Pentaho Data Integration: Which is better We compared these products and thousands more to help professionals like you find the perfect solution for your business. In the example below, the transformation adds information coming from a text-file (B) to data coming from a database table (A): Information from B is used to perform the lookups as indicated by the Source step option shown below. Note: Works only when 'Preserve memory' is checked. The data coming from the Source step is first read into memory and is then used to look up data from the main stream. Preserves memory while executing a sort by. Key and value are exactly one integer field More CPU cost related to calculating the hashcode, less memory needed.) (Technical background: Kettle will store the lookup data as raw bytes in a custom storage object that uses a hashcode of the bytes as the key. It does not convert the original type of the field.Д®ncodes rows of data to preserve memory while sorting. Note: The Type of the Default value does only provide the data type for the conversion of the Default value. You can specify the names of the fields to retrieve here, as well as the default value in case the value was not found or a new field name in case you didn't like the old one. Values are always searched using the 'equal' comparison The step name where the lookup data is coming fromДЄllows you to specify the names of the fields that are used to look up values. Name of the step this name has to be unique in a single transformation
