Summary: IntegrationTestLoadSmallValues
Key: HBASE-26405
URL: https://issues.apache.org/jira/browse/HBASE-26405
Project: HBase
Issue Type: Test
Components: integration tests, test
Reporter: Andrew Kyle Purtell
Assignee: Andrew Kyle Purtell
Fix For: 2.5.0, 3.0.0-alpha-2
This integration test emulates a use case that stores a lot of small values
into a table that would likely be heavily indexed (ROW_INDEX_V1, small blocks,
etc.), an application that crowdsources weather (temperature) observation data.
This IT can be used to test and optimize compression settings for such cases.
It comes with a companion utility, HFileBlockExtracter, which extracts block
data from HFiles into a set of local files for use in training external
compression dictionaries, perhaps with ZStandard's 'zstd' utility.
See javadoc on class IntegrationTestLoadSmallValues for usage.
