QuakeWang opened a new pull request, #8272: URL: https://github.com/apache/paimon/pull/8272
### Purpose When a nested-key was configured together with a count limit, `agg` short-circuited with `if (acc.size() >= countLimit) return accumulator;`. This early return was shared with the no-key path, so once the nested array reached the limit, updates to existing keys (and `nested-sequence-field` updates) were silently dropped — the limit was meant to bound the number of distinct keys, not block in-place updates. This PR splits the two paths: the no-key path keeps the count-limit truncation, while the keyed path merges by key so existing keys are always updated and the limit only caps the number of new keys. ### Tests - `mvn test -pl paimon-core -Dtest=FieldAggregatorTest` -- This is an automated message from the Apache Git Service.
