std::shared_ptr<DatasetCache> mindspore::dataset::CreateDatasetCacheCharIF(session_id_type id, uint64_t mem_sz, bool spill, const std::optional<std::vector<char>> &hostname = std::nullopt, const std::optional<int32_t> &port = std::nullopt, const std::optional<int32_t> &num_connections = std::nullopt, const std::optional<int32_t> &prefetch_sz = std::nullopt)
Function to create a cache to be attached to a dataset.
Note
The reason for providing this API is that std::string will be constrained by the compiler option ‘_GLIBCXX_USE_CXX11_ABI’ while char is free of this restriction. Check API
mindspore::dataset::CreateDatasetCache
and find more usage.- Parameters
id – [in] A user assigned session id for the current pipeline.
mem_sz – [in] Size of the memory set aside for the row caching (default=0 which means unlimited, note that it might bring in the risk of running out of memory on the machine).
spill – [in] Spill to disk if out of memory.
hostname – [in] optional host name (default=std::nullopt, means to use “127.0.0.1”).
port – [in] optional port (default=std::nullopt, means to use 50052).
num_connections – [in] optional number of connections (default=std::nullopt, means to use 12).
prefetch_sz – [in] optional prefetch size (default=std::nullopt, means to use 20).
- Returns
Shared pointer to DatasetCache. If error, nullptr is returned.
