The runtime filter of Apache Doriz supports In/Min/Max/Bloom Filter. The query optimizer of Apache Doris is a combination of CBO and RBO. RBO supports constant folding, subquery rewriting, and predicate pushdown while CBO supports join reorder. The Apache Doris CBO is under continuous ...
specific indexes, join methods, join ordering, and so on, when creating the plan for a query. This may be useful in situations where the optimizer is not able to come up with the preferred plan, due to lack of optimizer statistics, high level of skew in data, data correlations, and ...
After we define our model, let’s start to train them. It is required to compile the network first with the loss function and optimizer function. This will allow the network to change weights and minimized the loss. model.compile(loss='mean_squared_error', optimizer='adam') Now to start ...
