writeToCopy

fun writeToCopy(data: ByteArray, offset: Int = 0, length: Int = data.size)

Writes a chunk of data to the server.

Each call is one protocol message and one flush, so chunks want to be substantial rather than row-sized. Nothing is validated against the target table here; the server checks the data when it parses it, and a malformed chunk surfaces from endCopy rather than from this call.

Parameters

data

The bytes to send.

offset

Where to start in data.

length

How many bytes to send.

Throws

InvalidOperationException

RESOURCE_CLOSED if the operation has already finished.
