Creating ScanBuilder¶

ScanBuilder newScanBuilder(
  CaseInsensitiveStringMap options)

Creates a ScanBuilder

Used when:

• DataSourceV2Relation logical operator is requested to computeStats
• GroupBasedRowLevelOperationScanPlanning logical optimization is executed
• V2ScanRelationPushDown logical optimization is executed
• MicroBatchExecution (Spark Structured Streaming) is requested for a logical query plan
• ContinuousExecution (Spark Structured Streaming) is created (and initializes a logical query plan)

Implementations¶

• FileTable
• JDBCTable
• KafkaTable
• MemoryStreamTable (Spark Structured Streaming)
• RatePerMicroBatchTable (Spark Structured Streaming)
• RateStreamTable (Spark Structured Streaming)
• RowLevelOperationTable
• TextSocketTable (Spark Structured Streaming)
