Hi, community I was investigating lattice recently and encountered some problems: 1. Lattice requires the estimated number of rows of cuboids (tiles) for optimization. I've found the method: `TileSuggester.StatisticsProviderImpl # getRowCount`, `LatticeStatisticProvider # cardinality`, but I found that they were not used finally, can anyone tell where the code I should dig.
2. Are there any designs on how to automatically recommend the lattice (how to make the initial recommendation, how to adjust the existing lattices based on the query frequency / existing lattice), I can not find them included in JIRA or doc(https://calcite.apache.org/docs/lattice.html) Looking forward to hearing from you. -- Regards!
