leventov opened a new issue #8887: Make Transformer single-threaded and get rid of `rowSupplierForValueMatcher` ThreadLocal
URL: https://github.com/apache/incubator-druid/issues/8887
 
 
   `Transformer`'s `ThreadLocal rowSupplierForValueMatcher` doesn't need to be an instance field for the same reasons as `IncrementalIndex`'s `ThreadLocal in` field (see #8886). In the case of `Transformer`, it would be actually better to make it a single-threaded class right away and remove a `ThreadLocal` from inside `Transformer`, forcing users of the class to produce copies of `Transformer` per-task (worker, firehose, etc), if they need it.
