org.apache.accumulo.core.client.admin.CompactionStrategyConfig
@Deprecated(since="2.1.0", forRemoval=true) public class CompactionStrategyConfig extends Object
Deprecated, for removal: This API element is subject to removal in a future version.
since 2.1.0 CompactionStrategies were deprecated for multiple reasons. First, they do not support the new compaction execution model. Second, they bind selection and output file configuration into a single entity when users need to configure these independently. Third, they use internal Accumulo types and ensuring their stability requires manual effort that may never happen. Fourth, writing a correct compaction strategy was exceedingly difficult as it required knowledge of internal tablet server synchronization in order to avoid causing scans to hang. Fifth although measure were taken to execute compaction strategies in the same manner as before, their execution in the new model has subtle differences that may result in suboptimal compactions. Please migrate to using CompactionConfig.setSelector(PluginConfig) and CompactionConfig.setConfigurer(PluginConfig) as soon as possible.
Configuration object which describes how a Compaction is run. Configuration objects are dependent upon the CompactionStrategy running insider the server. This class is used in conjunction with CompactionConfig.
Since:
1.7.0
