> Enhancing IPC client throughput via multiple connections per user
> -----------------------------------------------------------------
>
> Key: HADOOP-13144
> URL: https://issues.apache.org/jira/browse/HADOOP-13144
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ipc
> Reporter: Jason Kace
> Assignee: Íñigo Goiri
> Priority: Minor
> Attachments: HADOOP-13144-branch-2.9.001.patch,
> HADOOP-13144-branch-2.9.002.patch, HADOOP-13144-performance.patch,
> HADOOP-13144.000.patch, HADOOP-13144.001.patch, HADOOP-13144.002.patch,
> HADOOP-13144.003.patch
>
>
> The generic IPC client ({{org.apache.hadoop.ipc.Client}}) utilizes a single
> connection thread for each {{ConnectionId}}. The {{ConnectionId}} is unique
> to the connection's remote address, ticket and protocol. Each ConnectionId
> is 1:1 mapped to a connection thread by the client via a map cache.
> The result is to serialize all IPC read/write activity through a single
> thread for a each user/ticket + address. If a single user makes repeated
> calls (1k-100k/sec) to the same destination, the IPC client becomes a
> bottleneck.
