Base class for many options related to IO.

Member Function Documentation

Config()

template<class TDerived>

TSelf & NYT::TIOOptions< TDerived >::Config

(

TNode

)

Advanced options for reader/writer.

Readers/writers have many options not of all of them are supported by library. If you need such unsupported option, you might use Config option until option is supported.

Example:

TTableWriterOptions().Config(TNode()("max_row_weight", 64 << 20)))

Note

We encourage you to ask yt@ to add native C++ support of required options and use Config only as temporary solution while native support is not ready.

CreateTransaction()

template<class TDerived>

TSelf & NYT::TIOOptions< TDerived >::CreateTransaction

(

bool

)

Whether to create internal client transaction for reading / writing table.

This is advanced option.

If CreateTransaction is set to false reader/writer doesn't create internal transaction and doesn't lock table. This option is overridden (effectively false) for writers by NYT::TTableWriterOptions::SingleHttpRequest

WARNING: if CreateTransaction is false, read/write might become non-atomic. Change ONLY if you are sure what you are doing!
