-The LDBC SNB Data Generator (Datagen) is responsible for providing the datasets used by the [LDBC Social Network Benchmark's workloads](https://ldbcouncil.org/benchmarks/snb/). The generator is designed to produce directed labelled graphs that mimic the characteristics of those graphs of real data. A detailed description of the schema produced by Datagen, as well as the format of the output files, can be found in the latest version of official [LDBC SNB specification document](https://github.com/ldbc/ldbc_snb_docs).

 :warning: There are two different versions of the Datagen:
 
-* The [Hadoop-based Datagen](https://github.com/ldbc/ldbc_snb_datagen_hadoop/) generates the Interactive SF1-1000 data sets.
+* The [Hadoop-based Datagen](https://github.com/ldbc/ldbc_snb_datagen_hadoop/) generates the Interactive workload's SF1-1000 data sets.
 * For the BI workload, use the Spark-based Datagen (in this repository).
 * For the Interactive workloads's larger data sets, there is no out-of-the-box solution (see [this issue](https://github.com/ldbc/ldbc_snb_interactive/issues/173)).
