TiStrategy

case class TiStrategy(getOrCreateTiContext: (SparkSession) ⇒ TiContext)(sparkSession: SparkSession) extends Strategy with Logging with Product with Serializable

CHECK Spark org.apache.spark.sql.Strategy

TODO: Too many hacks here since we hijack the planning but we don't have full control over planning stage We cannot pass context around during planning so a re-extract needed for push-down since a plan tree might contain Join which causes a single tree have multiple plans to push-down
