EmmyMiao87 opened a new pull request #3036: Support different keys type between mv and base table URL: https://github.com/apache/incubator-doris/pull/3036 Firstly, add materialized index meta in olap table The materialized index meta include index name, schema, schemahash, keystype etc. The information itself scattered in each map is encapsulated into MaterializedIndexMeta. Also the keys type of index meta maybe not same as keys type of base index after materialized view enabled. Secondly, support the deduplicate mv. If there is group by or aggregation function in create mv stmt, the keys type of mv is agg. At the same time, the keys type of base table is duplicate. For example Duplicate table (k1, k2, v1) MV (k1, k2) group by k1, k2 It should be aggregated during executing mv.
