jackjlli opened a new pull request #5826: URL: https://github.com/apache/incubator-pinot/pull/5826
## Description Currently there are some existing use cases who use map structure for columns in the raw data during segment creation, while map structure support isn't completely done yet. Thus, these use cases happen to use the undefined behavior in Pinot and thus need to be identified. And there is no monitoring/alerting system during segment creation. This PR introduces a way to detect whether the input data are converted from a map to an array. The info is saved in the segment metadata, so that pinot-server can emits a metric to detect this behavior once the segment is downloaded. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
