hi all,
we use elasticsearch with storm, continuously making percolation request.
as you see above, percolator throughput decreases as time passes.
but we are not seeing any other problematic statistics, except that CPU
usage also decreases as throughput decreases.
can you guess any reason for this? we are using es v1.1.0
sincerely,

Do the amount of registered percolate queries also increase?
