pred column also needs to be filtered by expr, exclude delete condition column, delete condition column not need to be filtered, query engine does not need it, after _output_column_by_sel_idx, delete condition materialize column will be erase at the end of the block.
Eg:
delete from table where a = 10;
select b from table;
a column only effective in segment iterator, the block from query engine only contain the b column, so no need to filter a column by expr.
Sample analyzing need to get row count by using table.getRowCount(). This method is not updated in real time, which may cause the sample task to scan whole table.
This pr is to fix this. Set the flag that indicate the analyze job is for an empty table and skip scan the table. Meanwhile, don't reset updatedRows in this case.
Set hugeTableAutoAnalyzeIntervalInMillis = 0 because all default huge table size has been set to 0.
Before this PR, Paimon has created the schema of `VectorTable` by accessing meta information. However, once the schema of `VectorTable` in java is not same as `Block` in c++, BE will crashed, and there is no good way to troubleshoot errors.
Use id as where predicate to load column statistic cache. This could improve performance, because id is the first order key in column statistics table.
