Hardware Sizing

Zingg has been built to scale. Performance is dependent on

  • The number of records to be matched.

  • The number of fields to be compared against each other.

  • The actual number of duplicates.

Here are some performance numbers you can use to determine the appropriate hardware for your data.

  • 120k records of examples/febrl120k/test.csv take 5 minutes to run on a 4 core, 10 GB RAM local Spark cluster.

  • 5m records of North Carolina Voters take ~4 hours on a 4 core, 10 GB RAM local Spark cluster.

  • 9m records with 3 fields - first name, last name, email take 45 minutes to run on AWS m5.24xlarge instance with 96 cores, 384 gb RAM

If you have upto a few million records, it may be easier to run Zingg on a single machine in Spark local mode.
