Function check_error

The SQL_STATEMENT_NOT_YET_COMPLETE error will surface if we query a view in Materialize before data exists for that view. It is common to hit this error just after creating a view, particularly in testing or demo code. Since this error is likely transient, we should retry reading from the view instead of failing.

(e: Error)

/// Since this error is likely transient, we should retry reading from the view
/// instead of failing.
fn check_error(e: Error) -> Result<()> {
    if e.code() == Some(&SqlState::SQL_STATEMENT_NOT_YET_COMPLETE) {
        info!("Error querying, will try again... {}", e.to_string());
        Ok(())
    } else {
        Err(anyhow::Error::from(e))
    }
}
