Splinter is a new cloud in-memory key-value store that combats data movement between disaggregated storage and compute nodes with untrusted tenant extensions that are pushed to it at runtime. Splinter’s key insight is that storage extensions can use language-level isolation to eliminate hardware isolation overheads that cannot be avoided today: not with virtual machines, containers, nor serverless Lambdas. Splinter also eliminates copying data for safety, so extensions benefit from low-level hardware functionality like zero-copy network transmission.
