Detailed Description
Options for NYT::IClient::CreateTableWriter.
Member Function Documentation
◆ AutoFinish()
| TSelf & NYT::TTableWriterOptions::AutoFinish | ( | bool | ) |
Wheter to call Finish automatically in writer destructor.
If set to true (default) Finish() is called automatically in the destructor of writer. It is convenient for simple usecases but might be error-prone if writing exception safe code (In case of exceptions it's common to abort writer and not commit partial data).
If set to false Finish() has to be called explicitly.
◆ BufferSize()
| TSelf & NYT::TTableWriterOptions::BufferSize | ( | size_t | ) |
Allows to change the size of locally buffered rows before flushing to yt.
Used only with NYT::TTableWriterOptions::SingleHttpRequest
◆ FormatHints()
| TSelf & NYT::TTableWriterOptions::FormatHints | ( | TFormatHints | ) |
Allows to fine tune format that is used for writing tables.
Has no effect when used with raw-writer.
◆ InferSchema()
| TSelf & NYT::TTableWriterOptions::InferSchema | ( | bool | ) |
Try to infer schema of inexistent table from the type of written rows.
- Note
- Default values for this option may differ depending on the row type. For protobuf it's currently false by default.
◆ SingleHttpRequest()
| TSelf & NYT::TTableWriterOptions::SingleHttpRequest | ( | bool | ) |
Enable or disable retryful writing.
If set to true no retry is made but we also make less requests to master. If set to false writer can make up to TConfig::RetryCount attempts to send each block of data.
- Note
- Writers' methods might throw strange exceptions that might look like network error when SingleHttpRequest == true and YT node encounters an error (due to limitations of HTTP protocol YT node have no chance to report error before it reads the whole input so it just drops the connection).
◆ WriterOptions()
| TSelf & NYT::TTableWriterOptions::WriterOptions | ( | TWriterOptions | ) |
Options to control how YT server side writes data.
