Talek Server

Server code is divided between a 'Frontend', which receives requests from users, and relays them to the disparate trust domains, and 'Replica', which processes requests for an individual trust domain, by maintaining a copy of the database, which is updated and read by one or more 'Shard's.

Testing Shard Performance

Shard performance can be tested to understand read and write throughputs at different workloads and database sizes using the shard_test code.

An example is

go test -run 0 -bench BenchmarkShard -benchtime 1m

Workload / sizing parameters are controlled by the following environmental vars:

• PIR_SOCKET (default "pir.socket")
• READS_PER_WRITE (default 20)
• NUM_BUCKETS (default 512)
• BUCKET_DEPTH (default 4)
• DATA_SIZE (default 512)
• BATCH_SIZE (default 8)
