IPA Biweekly Meeting Agenda Request - IPA Sharding with Sensitivity Bounds #53

Closed eriktaubeneck closed 1 year ago

Agenda+: IPA Sharding with Sensitivity Bounds

In order to support the higher end of query sizes outlined in patcg/private-measurement: issue #21, it's almost certain that we will need a solution that horizontally scales. This presents some challenges in the IPA setting, as we would want to avoid a helper party learning which events land on which shard. Preventing this information leakage includes limiting information about the sizes of the shards, as well.

Issue #35 explores this in detail.

Time

This will take at least 30 min, potentially all 60.
