Revision 48e7effa79d1ab165e83b2f96455f77ffd79cca3 authored by Siying Dong on 26 March 2019, 02:14:04 UTC, committed by Facebook Github Bot on 26 March 2019, 02:18:04 UTC
Summary: With https://github.com/facebook/rocksdb/pull/3009 we go through every CF to check whether a bottommost compaction is needed to be triggered. This is done within DB mutex. What we do within DB mutex may heavily influece the write throughput we can achieve, so we always want to minimize work there. Here we try to avoid this for-loop by first check a global threshold. In most of the time, the CF loop can be avoided.

README
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.
