```
    Returns whether to look for the result in the query cache
  - getFlattenResults
```
@Nullable
public abstract Boolean getFlattenResults()
```
    Returns whether nested and repeated fields should be flattened. If set to false ConnectionSettings.Builder.setAllowLargeResults(Boolean) must be true.
    
    See Also:
    
    Flatten
  - getClustering
```
@Nullable
public abstract Clustering getClustering()
```
    Returns the clustering specification for the destination table.
  - getCreateDisposition
```
@Nullable
public abstract JobInfo.CreateDisposition getCreateDisposition()
```
    Returns whether the job is allowed to create new tables.
    
    See Also:
    
    Create Disposition
  - getDestinationEncryptionConfiguration
```
@Nullable
public abstract EncryptionConfiguration getDestinationEncryptionConfiguration()
```
    Returns the custom encryption configuration (e.g., Cloud KMS keys)
  - getDestinationTable

  - getAllowLargeResults
```
@Nullable
public abstract Boolean getAllowLargeResults()
```
    Returns whether the job is enabled to create arbitrarily large results. If true the query is allowed to create large results at a slight cost in performance. the query is allowed to create large results at a slight cost in performance.
    
    See Also:
    
    Returning Large Query Results
  - getCreateSession

  - getSchemaUpdateOptions
```
@Nullable
public abstract List<JobInfo.SchemaUpdateOption> getSchemaUpdateOptions()
```
    [Experimental] Returns options allowing the schema of the destination table to be updated as a side effect of the query job. Schema update options are supported in two cases: when writeDisposition is WRITE_APPEND; when writeDisposition is WRITE_TRUNCATE and the destination table is a partition of a table, specified by partition decorators. For normal tables, WRITE_TRUNCATE will always overwrite the schema.
  - getTableDefinitions
```
@Nullable
public abstract Map<String,ExternalTableDefinition> getTableDefinitions()
```
    Returns the external tables definitions. If querying external data sources outside of BigQuery, this value describes the data format, location and other properties of the data sources. By defining these properties, the data sources can be queried as if they were standard BigQuery tables.
  - getTimePartitioning
```

public abstract TimePartitioning getTimePartitioning()
```
    Returns the time partitioning specification for the destination table.
  - getUserDefinedFunctions
```
@Nullable
public abstract List<UserDefinedFunction> getUserDefinedFunctions()
```
    Returns user defined function resources that can be used by this query. Function resources can either be defined inline (UserDefinedFunction.Type.INLINE) or loaded from a Google Cloud Storage URI (UserDefinedFunction.Type.FROM_URI.
  - getWriteDisposition
```
@Nullable
public abstract JobInfo.WriteDisposition getWriteDisposition()
```
    Returns the action that should occur if the destination table already exists.
    
    See Also:
    
    Write Disposition
  - toBuilder
```
public abstract ConnectionSettings.Builder toBuilder()
```

  - newBuilder
```
public static ConnectionSettings.Builder newBuilder()
```
    Returns a builder for a ConnectionSettings object.
