Summary: This diff adds timeout_hint_us to WriteOptions. If it's non-zero, then 1) writes associated with this options MAY be aborted when it has been waiting for longer than the specified time. If an abortion happens, associated writes will return Status::TimeOut. 2) the stall time of the associated write caused by flush or compaction will be limited by timeout_hint_us. The default value of timeout_hint_us is 0 (i.e., OFF.) The statistics of timeout writes will be recorded in WRITE_TIMEDOUT. Test Plan: export ROCKSDB_TESTS=WriteTimeoutAndDelayTest make db_test ./db_test Reviewers: igor, ljin, haobo, sdong Reviewed By: sdong Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D18837
This directory contains interfaces and implementations that isolate the rest of the package from platform details. Code in the rest of the package includes "port.h" from this directory. "port.h" in turn includes a platform specific "port_<platform>.h" file that provides the platform specific implementation. See port_posix.h for an example of what must be provided in a platform specific header file.
