CAVEAT: when using with transactions destructor of TTempTable should be called before commiting transaction.

Constructor & Destructor Documentation

TTempTable()

NYT::TTempTable::TTempTable ( IClientBasePtr client, const TString & prefix = {}, const TYPath & directory = {}, const TCreateOptions & options = {} )

explicit

Constructor creates temporary table.

Parameters

client	– YT client or transaction object.
prefix	– table name prefix
directory	– path to directory where temporary table will be created.
options	– options to be passed for table creation (might be useful if we want to set table attributes)

Member Function Documentation

CreateAutoremovingTable()

TTempTable NYT::TTempTable::CreateAutoremovingTable ( IClientBasePtr client, TYPath path, const TCreateOptions & options )

static

Create table with given path that will be autoremoved in RAII manner.

In contrast to TTempTable constructor this function uses provided path to table and don't modify it in any manner. It's user responsibility to provide unique path.
