Struct ArrowImportOptions 

Source
pub struct ArrowImportOptions {
    pub schema: Option<String>,
    pub columns: Option<Vec<String>>,

}
Expand description

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

Whether to use TLS encryption for transport

§host: String

Exasol host for HTTP transport connection. This is typically the same host as the WebSocket connection.

§port: u16

Exasol port for HTTP transport connection. This is typically the same port as the WebSocket connection.

Implementations§

Source§

impl ArrowImportOptions

Source

pub fn new() -> Self

Create new options with default values.

Source

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

Source

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

Source

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

Source

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

Source

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

Source

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

Source

pub fn with_encryption(self) -> Self

Source

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