Method Detail
- init
```
public void init(TableConfig tableConfig,
                 Schema schema,
                 TableDataManager tableDataManager,
                 org.apache.helix.HelixManager helixManager,
                 @Nullable
                 ExecutorService segmentPreloadExecutor)
```
  Specified by:
  
  init in interface TableUpsertMetadataManager
- initCustomVariables
```
protected void initCustomVariables()
```
  Can be overridden to initialize custom variables after other variables are set but before preload starts. This is needed because preload will load segments which might require these custom variables.
- onPreloadStart
```
protected boolean onPreloadStart()
```
  Can be overridden to perform operations before preload starts.
  
  Returns:
  
  whether to continue the preloading logic.
- onPreloadFinish
```
protected void onPreloadFinish()
```
  Can be overridden to perform operations after preload is done.
- isPreloading
```
public boolean isPreloading()
```
  Specified by:
  
  isPreloading in interface TableUpsertMetadataManager
- getUpsertMode
```
public UpsertConfig.Mode getUpsertMode()
```
  Specified by:
  
  getUpsertMode in interface TableUpsertMetadataManager
