Jackie-Jiang opened a new issue #5577: URL: https://github.com/apache/incubator-pinot/issues/5577
For historic reason, BrokerRequest does not support expressions natively. In order to support expressions (transform), the current solution is to store the expressions as strings and compile them when constructing the operators. The problem with this approach is that the same compilation is performed multiple times on EACH segment. This could cause performance degradation when the server is hosting lots of segments. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
