Create tables in ClickHouse: https://github.com/alexey-milovidov/ssb-clickhouse/blob/cc8fd4d9b99859d12a6aaf46b5f1195c7a1034f9/create.sql
For single-node setup, create just MergeTree tables.
For Distributed setup, you must configure cluster `perftest_3shards_1replicas` in configuration file.
Then create MergeTree tables on each node and then create Distributed tables.
Load data (change customer to customerd in case of distributed setup):
```
cat customer.tbl | sed 's/$/2000-01-01/' | clickhouse-client --query "INSERT INTO customer FORMAT CSV"
```
