- 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
