The following scripts performs the following:

• Create the schema (keyspace, table and secondary indexes)
• Emulate 10K sensors, each sensor emitting 2000 data points, while using prepared statements

Pre-requisites

• python 2.7
• Cassandra driver: pip install cassandra-driver
• Scylla cluster up and running
• experimental: true enabled in scylla.yaml file (needed for secondary indexes in v2.1)

How to run

1. Download the file
2. Run: python [file_name].py -c [scylla nodes IP, comma separated] &
   • Example: python 1_insert_ts_direct_new.py -c 172.16.0.62,172.16.0.204,172.16.0.67 &
3. If you need to emulate more sensors, just clone the script and change start_range1 to the start of the next range.
