Member Data Documentation

assorted::FixedString<60> foedus::memory::PagePoolControlBlock::debug_pool_name_

just for debugging/logging.

concise description of this pool instance. eg "VolatilePool-3".

Definition at line 58 of file page_pool_pimpl.hpp.

Referenced by foedus::memory::PagePoolPimpl::attach(), foedus::memory::PagePoolPimpl::get_debug_pool_name(), and foedus::memory::PagePoolPimpl::set_debug_pool_name().

uint64_t foedus::memory::PagePoolControlBlock::free_pool_count_

Number of free pages.

Definition at line 55 of file page_pool_pimpl.hpp.

Referenced by foedus::memory::PagePoolPimpl::decrease_free_pool_count(), foedus::memory::PagePoolPimpl::get_free_pool_count(), foedus::memory::PagePoolPimpl::increase_free_pool_count(), and foedus::memory::PagePoolPimpl::initialize_once().

uint64_t foedus::memory::PagePoolControlBlock::free_pool_head_

Inclusive head of the circular queue.

Be aware of wrapping around.

Definition at line 53 of file page_pool_pimpl.hpp.

Referenced by foedus::memory::PagePoolPimpl::free_pool_head(), and foedus::memory::PagePoolPimpl::initialize_once().

soc::SharedMutex foedus::memory::PagePoolControlBlock::lock_

grab()/release() are protected with this lock.

This lock is not contentious at all because we pack many pointers in a chunk.
