Using functions in the filter function on variable length data failed¶

What is new - 25.1¶

The filter function did not work correctly with variable-length text fields. Specifically, filtering on empty customer comments (e.g., len(comments) = 0 or trim(comments) = '') fails.

With this change in v25.1, it will work, but since functions cannot be off-loaded to the database server, it may have a significant impact on performance as all data needs to be read during filtering. Previous versions skipped reading the data.
