# Tikv Client

+ `grpc-connection-count` 
  + Set the number of grpc connections between TiDB and each TiKV. When a large number of concurrent request are sent to one grpc connection, a single gRPC connection sends request serially, may become a bottleneck. When the GPRC connection becomes the bottleneck, setting a larger number of gRPC connections can improve performance, but at the cost of consuming more system resources.
