Sample config ​

yaml
skippr:
  workspace: mssql_to_clickhouse
pipelines:
  mssql_to_clickhouse:
    data_source: data_sources.source
    data_sink: data_sinks.warehouse
data_sources:
  source:
    Mssql:
      connection_string: "${MSSQL_CONNECTION_STRING}"
data_sinks:
  warehouse:
    Clickhouse:
      url: "http://localhost:8123"
      database: default
      user: default

Environment ​

bash
export CLICKHOUSE_URL="http://localhost:8123"
export CLICKHOUSE_USER="default"
export CLICKHOUSE_PASSWORD="mypassword"
export MSSQL_CONNECTION_STRING="server=tcp:127.0.0.1,1433;database=testdb;user id=sa;password=YourPass;TrustServerCertificate=true"

Source connector: mssql. Destination connector: clickhouse-warehouse.
