Is there any Negative Impact on increasing semaphore count?

What is the negative impact on increasing semaphore count while implementing HystixObservable command. hystrix.command.default.execution.isolation.semaphore.maxConcurrentRequests = 1000?

we are using netflix hystrix for fault tolerance in our application and we need to provide semaphore count in order to avoid "Caused by: java.lang.RuntimeException: could not acquire a semaphore for execution"

Default count of semaphore is 10 and we increased to 1000 and application is working as expected but I wanted to see if there is any negative impact if we increase the semaphore ?

execution: isolation: semaphore: maxConcurrentRequests : 1000
