Partition points mark the points in the pipeline where the Integration Service can redistribute data across partitions. By default Integration Service will keep partition at various transformations. Partition points marks the boundaries that divide the pipeline into stages. Set the partition points in the mapping.The integration service will run the partition threads concurrently. Mapping will be subdivided into many pipelines are called stage pipeline.Īfter enabling partitioning in stage pipeline when we run the integration service it runs faster and we can expect more performance. Pipeline partitioning a mapping in Informatica means to partition the pipeline inside the mapping.Ī pipeline will contain the source, transformation and targets. Explain the pipeline partition with real time example? Assignment: To assign values work-let or work flow variablesģ.Timer: To halt the process for specific time.Decission: Condition to be evaluated for controlling flow or process.Event raise: To raise active User_Defined Event.Event wait: For Pre_Defined or Post_Defined Events.How many types of sessions are there in Informatica? Then it can be better use sorted joiner, which throws data to output as reads them on input.Ģ. If database responses slowly or big amount of data are processed, lookup cache initialization can be really slow. In case of database, lookup can be effective if he database can return sorted data fast and the amount of data is small, because lookup can create whole cache in memory.If the file is not sorted, it can be comparable. In case of Flat file, generally, sorted joiner is more effective than lookup, because sorted joiner uses join conditions and caches less rows.Sometimes joiner gives more performance and sometimes lookups. Can’t compare lookup and joiner since each has its own functions.
Which one is better performance wise joiner or look up?
