  • Version 2.4.1 (2021-09-02)

Noteworthy Changes:

  • Add a config flag to enable splitting queries across the rollup and
    raw data tables. Another config determines when to split the queries.

    a filter.
  • Collect stats from meta cache plugins.

    instead of the multi-port TSD script.

Bug Fixes:

  • Fix the "--sync" flag for FSCK to wait for repairs to execute against
    storage before proceeding.
  • Fix expression queries to allow metric only and filterless queries.
  • Fix an NPE in /api/query/last when appends are enabled.
  • Fix races in the salt scanner and multigets on the storage maps.
  • Fix rollup queries that need sum and count for downsampling instead of
    group bys.
  • Fix fuzzy row filters for later versions of HBase by using filter pairs.
    And allow it to be combined with a regex filter.
  • Fix stats from the individual salt scanners and overall query stats
    concurrency issues.
  • Rename the stat "maxScannerUidtoStringTime" to
    "maxScannerUidToStringTime"

OpenTSDB 2.4.0 RC2

Pre-release
Pre-release
  • Version 2.4.0 RC2 (2017-10-08)

Noteworthy Changes:

  • Modify the RPC handler plugin system so that it parses only the first part of
    the URI instead of the entire path. Now plugins can implement sub-paths.
  • Return the HTML 5 doctype for built-in UI pages
  • Add an optional byte and/or data point limit to the amount of data fetched
    from storage. This allows admins to prevent OOMing TSDs due to massive queries.
  • Allow a start time via config when enabling the date tiered compaction in HBase
  • Provide the option of using an LRU for caching UIDs to avoid OOMing writers and
    readers with too many strings
  • Optionally avoid writing to the forward or reverse UID maps when a specific TSD
    operational mode is enabled to avoid wasting memory on maps that will never be
    used.

Bug Fixes:

  • Roll back UTF8 issue with UIDs in RC1 wherein the stored bytes weren't converting
    properly and vice-versa. We'll have to work on full UTF8 support in 3.x
  • Fix a build issue for Javacc
  • Add Kryo as a dependency to the fat jar
  • Javadoc fixes
  • Fix an issue with calendar aligned downsampling by seeking to the start time of
    the query when the zone-aligned timestamp may be earlier than the query start time
  • Add the missing QueryLimitOverride to the makefile
  • Fix compatibility with Bigtable for 2.4
  • Enable standard read-only APIs when the TSD is in write only mode

  • Version 2.2.2 (2016-12-29)

Bug Fixes:

  • Fix an issue with writing metadata where using custom tags could cause the compare-
    and-set to fail due to variable ordering in Java's heap. Now tags are sorted so the
    custom tag ordering will be consistent.
  • Fix millisecond queries that would miss data the top of the final hour if the end
    time was set to 1 second or less than the top of that final hour.
  • Fix a concurrent modification issue where salt scanners were not synchronized on the
    annotation map and could cause spinning threads.

  • Version 2.2.1 (2016-10-08)

Noteworthy Changes

  • Generate an incrementing TSMeta request only if both enable_tsuid_incrementing and
    tsd.core.meta.enable_realtime_ts are enabled. Previously, increments would run

    incrementing is disabled then a get and optional put is executed each time without
    modifying the meta counter field.
  • Improve metadata storage performance by removing an extra getFromStorage() call.
