Claim 7:
8. A data stream processing environment, the data stream processing environment comprising:
a data lake data store storing records of a data stream;
a data filter configured to receive the data stream, and filter the data stream to produce a filtered output;
a streaming data filter configuration tool coupled to the data lake data store and to the data filter, wherein the streaming data filter configuration tool is configured to:
generate a representative sample of the data stream, the representative sample including:
a first set of sample elements comprising real-time sample elements directly sampled from the data stream; and
a second set of sample elements comprising previously stored sample elements of the data stream, sampled from the data lake data store;

input one or more filter parameters for the data filter from a workstation user interface;
compute one or more filter statistics estimates that represent applying the one or more filter parameters to the data stream, based on applying the one or more filter parameters to the representative sample;
output to the workstation user interface the one or more filter statistics estimates for the one or more filter parameters; and
configure the data filter to apply the one or more filter parameters to the data stream in response to an instruction from the workstation user interface.
