--------------------------------
Summary: Explore reducing number of data blocks by tuning existing
parameters
Key: KUDU-1971
URL: https://issues.apache.org/jira/browse/KUDU-1971
Project: Kudu
Issue Type: Sub-task
Components: tablet
Affects Versions: 1.4.0
Reporter: Adar Dembo
One way to scale to larger on-disk data sets is to reduce the ratio between
data blocks and data; that is, to make data blocks larger. Two existing
parameters control for this:
* budgeted_compaction_target_rowset_size: within a given flush or compaction
operation, stipulates the size of each rowset. Currently 32M.
* tablet_compaction_budget_mb: stipulates the amount of data that should be
included in any given compaction. Currently 128M.
It might be interesting to explore raising these.
