@mrpringle: Anyone setup CueObserve with Pinot; see they recently merged in pinot support?
@mrpringle: Some more things from my wishlist; 1. any example aggregation functions which can combine previous aggregates e.g. for different products to sum(LASTWITHTIME( sales, saleTime ) ) WHERE saleTime between x and y. So aggregate of an aggregate without having to do this in python. 2. grafana support

#troubleshooting
@elon.azoulay: If a table is taking a long time to delete (due to server crashes - this is staging) is it safe to delete from zk, remove the segment files from disk and deepstore. Should restart the controllers, brokers and servers that the segment was on?
@elon.azoulay: If it takes too long I will try this and update:)
@elon.azoulay: Ah, and remove from brokerResource
@mayanks: A table has multiple related entries in zk, which ones are you referring to (don’t forget the segment Zk metadata)

@mathieu.druart: Hi ! We are trying to use lookup join to get a multivalued String column from a small dimension table but we have this exception during request : ``` "message": "QueryExecutionError:\njava.lang.ClassCastException: class [Ljava.lang.Object; cannot be cast to class [Ljava.lang.String; ([Ljava.lang.Object; and [Ljava.lang.String; are in module java.base of loader 'bootstrap')\n\tat org.apache.pinot.core.operator.transform.function.LookupTransformFunction.transformToStringValuesMV(LookupTransformFunction.java:328)\n\tat org.apache.pinot.core.operator.docvalsets.TransformBlockValSet.getStringValuesMV(TransformBlockValSet.java:125)\n\tat org.apache.pinot.core.common.RowBasedBlockValueFetcher.createFetcher(RowBasedBlockValueFetcher.java:81)\n\tat org.apache.pinot.core.common.RowBasedBlockValueFetcher.<init>(RowBasedBlockValueFetcher.java:32)",``` If you have any idea, thank you !
@mayanks: What’s the query and what version of Pinot are you using?
