In many cases, the data that is supposed to be stored in MonetDB is created by a large-scale data aggregation process. Apache Pig is a popular tool for this task. There is a possibility of directly generating MonetDB binary column files using the MonetDB-Pig-Layer.
Inside a Pig script, this is used as follows:
STORE raw INTO './results/' USING nl.cwi.da.monetdb.loader.hadoop.MonetDBStoreFunc;
