> Key: BEAM-7513
> URL: https://issues.apache.org/jira/browse/BEAM-7513
> Project: Beam
> Issue Type: New Feature
> Components: dsl-sql, io-java-gcp
> Reporter: Alireza Samadianzakaria
> Assignee: Alireza Samadianzakaria
> Priority: Major
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> Calcite tables (org.apache.calcite.schema.Table) should implement the method
> org.apache.calcite.schema.Statistic getStatistic(). The Statistic instance
> returned by this method is used for the Volcano optimizer in Calcite.
> Currently, org.apache.beam.sdk.extensions.sql.impl.BeamCalciteTable has not
> implemented getStatistic() which means it uses the implementation in
> org.apache.calcite.schema.impl.AbstractTable and that implementation just
> returns Statistics.UNKNOWN for all sources.
>
> Things needed to be implemented:
> 1- Implementing getStatistic in BeamCalciteTable such that it calls a row
> count estimation method from BeamSqlTable and adding this method to
> BeamSqlTable.
> 2- Implementing the row count estimation method for BigQueryTable.
