// Package nrsnowflake instruments github.com/snowflakedb/gosnowflake
//
// Use this package to instrument your Snowflake calls without having to manually
// create DatastoreSegments. This is done in a two step process:
//
// 1. Use this package's driver in place of the snowflake driver.
//
// If your code is using sql.Open like this:
//
// import (
// _ "github.com/snowflakedb/gosnowflake"
// )
//
// func main() {
// db, err := sql.Open("snowflake", "user@unix(/path/to/socket)/dbname")
// }
//
// Then change the side-effect import to this package, and open "nrsnowflake" instead:
//
// import (
// _ "github.com/newrelic/go-agent/v3/integrations/nrsnowflake"
// )
//
// func main() {
// db, err := sql.Open("nrsnowflake", "user@unix(/path/to/socket)/dbname")
// }
//
// 2. Provide a context containing a newrelic.Transaction to all exec and query
// methods on sql.DB, sql.Conn, sql.Tx, and sql.Stmt. This requires using the
// context methods ExecContext, QueryContext, and QueryRowContext in place of
// Exec, Query, and QueryRow respectively. For example, instead of the
// following:
//
// row := db.QueryRow("SELECT count(*) from tables")
//
// Do this:
//
// ctx := newrelic.NewContext(context.Background(), txn)
// row := db.QueryRowContext(ctx, "SELECT count(*) from tables")
//
// A working example is shown here:
// https://github.com/newrelic/go-agent/tree/master/v3/integrations/nrsnowflake/example/main.go
