In traditional client-server designs, all requests are processed
\nat the server storing the state, thereby maintaining
\nstrict locality between computation and state. The adoption
\nof RDMA (Remote Direct Memory Access) makes
\nit practical to relax locality by letting clients fetch server
\nstate and process requests themselves. Such client-side
\nprocessing improves performance when the server CPU,
\ninstead of the network, is the bottleneck.We observe that
\ncombining server-side and client-side processing allows
\nsystems to balance and adapt to the available CPU and
\nnetwork resources with minimal configuration, and can
\nfree resources for other CPU-intensive work.
\nWe present Cell, a distributed B-tree store that combines
\nclient-side and server-side processing. Cell distributes
\na global B-tree of \u201cfat\u201d (64MB) nodes across
\nmachines for server-side searches. Within each fat node,
\nCell organizes keys as a local B-tree of RDMA-friendly
\nsmall nodes for client-side searches. Cell clients dynamically
\nselect whether to use client-side or server-side processing
\nin response to available resources and the current
\nworkload. Our evaluation on a large RDMA-capable
\ncluster show that Cell scales well and that its dynamic
\nselector effectively responds to resource availability and
\nworkload properties.<\/p>\n","protected":false},"excerpt":{"rendered":"
