shauryachats opened a new pull request, #16242:
URL: https://github.com/apache/pinot/pull/16242

   This PR introduces support for configuring the default hash function used by 
`KeySelector` during query planning and data shuffling. The broker can now 
specify the default via a new config:
   `pinot.broker.default.hash.function` (default: `absHashCode`).
   
   Key Changes:
   - Added defaultHashFunction to broker config and propagated it through 
`QueryEnvironment` to planning layers.
   - Updated `KeySelector` implementations (`SingleColumn`, `MultiColumn`, 
`Empty`) to support configurable hashing.
   - Introduced `HashFunctionSelector` utility for standardized hashing using 
algorithms like absHashCode, murmur2, murmur3, and cityhash.
   - Updated `ExchangeNode` and `MailboxSendNode` to carry the hash function.
   
   This enables better control over data distribution strategies in multistage 
query execution.
