Struct ArrowImportOptions 

pub struct ArrowImportOptions {
    pub schema: Option<String>,
    pub columns: Option<Vec<String>>,
    pub batch_size: usize,
    pub csv_options: CsvWriterOptions,
    pub use_encryption: bool,
    pub host: String,
    pub port: u16,
}

Options for Arrow import operations.

Fields

schema: Option<String>

Target schema name (optional)

columns: Option<Vec<String>>

Columns to import (optional, imports all if None)

batch_size: usize

Batch size for chunked processing (default: 10000)

csv_options: CsvWriterOptions

CSV writer options

use_encryption: bool

Implementations

impl ArrowImportOptions

pub fn new() -> Self

Create new options with default values.

pub fn schema(self, schema: impl Into<String>) -> Self

pub fn columns(self, columns: Vec<String>) -> Self

pub fn batch_size(self, size: usize) -> Self

pub fn null_value(self, value: impl Into<String>) -> Self

pub fn column_separator(self, sep: char) -> Self

pub fn column_delimiter(self, delim: char) -> Self

pub fn with_encryption(self) -> Self

pub fn exasol_host(self, host: impl Into<String>) -> Self

Set the Exasol host for HTTP transport connection.

This should be the same host as used for the WebSocket connection.

pub fn exasol_port(self, port: u16) -> Self

Set the Exasol port for HTTP transport connection.

This should be the same port as used for the WebSocket connection.
