             Summary: Optimization whether to query Bootstrapped table using HoodieBootstrapRelation vs Sparks Parquet datasource
                 Key: HUDI-1157
                 URL: https://issues.apache.org/jira/browse/HUDI-1157
             Project: Apache Hudi
          Issue Type: Sub-task
          Components: bootstrap
            Reporter: Udit Mehrotra


This has been discussed in [https://github.com/apache/hudi/pull/1702#discussion_r466317612]

As of now, while querying using *DataSource* we are checking if the table has been bootstrapped by the present of *bootstrap base path* in *hoodie.properties* file, and based on that query the table using *HoodieBootstrapRelation*  vs *Spark Parquet Data Source*. However, there could be a scenario where all the files in the originally bootstrapped table have wither been *upserted/deleted* and thus have been fully bootstrapped and their data has been moved over to the target hoodie table. For such tables, we can start querying them using *Spark Parquet Data Source* which will be faster with all of spark's optimizations.

So, basically we a need a way to check if all of the files have been fully bootstrapped and moved over to the target location.
