Clear BgExecutor queue by job name

bge_clear_queue.rb

bgkey =  ::BgExecutor::Configuration[:redis][:namespace] + ':bg_executor:jobs_queue'
job_name = 'worker:mail' # 'map_coord'

# Test:
result = []

($redis.llen bgkey).times { |idx| p idx if idx % 100 == 0; val = ($redis.lindex bgkey, idx).to_s; result << val if val.include?(job_name) }
# And Run:
# result.each { |val| $redis.lrem bgkey, 0, val }
# NOT ($redis.llen bgkey).times { |idx| val = ($redis.lindex bgkey, idx); $redis.lrem bgkey, 0, val if val.include?(job_name) }
