2.6.0 (2024-05-28)

  • Add support for switch from mmap to pread for message reads due to bad interaction with mmap on certain filesystems.
  • Correct issue where bulk message reads did not work with compression enabled.
  • Fix issue where short writes could happen due to failing to check the return value of pwritev.

2.5.4 (2022-09-20)

  • No longer perform an unneeded ownership check on the parent directory. This silences an erroneous/misleading jlogctl error message.

  • Correct issue where writing to pre-commit buffer could cause jlog to advance with a zero-sized log segment.
  • Make jlogctl alter -p work.
  • Make jlogctl repair maintain all pre-existing valid meta fields.
  • jlog_ctx_read_interval now will automatically advance past more than one missing data files.

2.5.2 (2020-06-11)

  • Add an ownership check after jlogctl runs to alert operators to potentially unusable file ownership problems.

2.5.1 (2020-06-08)

  • Add a 'meta' subcommand to assist metastore inspection.
