Release Notes

4.6.5

Bindings

4.6.4

Features

  • Added ability to use –io_trust_seconds in a warn-only mode, which logs a trace event rather than failing the process when a disk operation takes a long time. This is enabled with –io_trust_warn_only. <rdar://problem/32344389>

Fixes

  • Disk operation timeouts now cause the process to restart rather than hang indefinitely. <rdar://problem/31888796>

  • fdbdr switch did not start the DR in the opposite direction correctly, resulting in mutations being lost. <rdar://problem/32598128>

  • Lowered backup and DR batch sizes to avoid large packet warnings. <rdar://problem/30933203>

  • Remove partial pipelining of tlog commits.
