Jian Zhang updated HDFS-17545:
------------------------------
Description:
*Describe*
1. Mainly using AsyncUtil to implement {*}RouterAsyncRpcClient{*}, this classÂ
extends RouterRpcClient, enabling the {*}invoiceAll{*}, {*}invoiceMethod{*},
{*}invoiceSequential{*}, {*}invoiceConcurrent{*}, and *invoiceSingle* methods
to support asynchrony.
2. Use two thread pools, *asyncRouterHandler* and {*}asyncRouterResponder{*},
to handle asynchronous requests and responses, respectively.
3. Added {*}DFS_ROUTER_RPC_ENABLE_ASYNC{*},
{*}DFS_ROUTER_RPC_ASYNC_HANDLER_COUNT{*},
*DFS_ROUTER_RPC_ASYNC_RESPONDER_COUNT_DEFAULT* to configure whether to use
async router, as well as the number of asyncRouterHandlers and
asyncRouterResponders.
4. Using *ThreadLocalContext* to maintain thread local variables, ensuring that
thread local variables can be correctly passed between handler,
asyncRouterHandler, and asyncRouterResponder.
Note: For discussions on *AsyncUtil* and client {*}protocolPB{*}, please refer
to HDFS-17543 and HDFS-17544.
