The Impala query will power a dashboard which will be updated every few minutes. Do you have to do regularly "invalidate metadata". But that takes too long. Is there a faster way of doing this?</P> Fri, 16 Sep 2022 08:56:53 GMT yash.ranadive 2022-09-16T08:56:53Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Is-there-a-way-to-query-streaming-data-from-storm-in-impala/m-p/8562#M1518 <P>We want an architecture where streaming data from Storm is landed on to a table folder which can be picked up by Impala.

This will incrementally update the specified table's metadata rather than clearing all cached metadata, so it should be faster.
