TigerBeetle Virtual Threads Benchmark

This experiment measures how long it takes to execute 10,000 individual transfers between random accounts using TigerBeetle and Java virtual threads.

Overview

• Language: Java 21+ with Project Loom virtual threads
• Library: TigerBeetle Java client v0.16.x
• Testbed: Local TigerBeetle cluster (no replication), Docker or native install on laptop
• Machine: MacBook Pro i9, 32 GB RAM

What the code does

1. Establishes a connection to a single-node TigerBeetle cluster on port 3000.
2. Spawns a pool of 10000 virtual threads.
3. Submits 10,000 tasks, each task does:
   • Generate random IDs for debit account, credit account and transfer.
   • Create both accounts if they don’t exist.
   • Issue a transfer of amount = 10.
   • Lookup both account balances.
   • Verify debit and credit were applied correctly.
4. Shuts down the thread pool and waits for up to 10 s for all tasks to finish.
5. Prints elapsed time for the entire operation.

Results

• Total transfers: 10,000
• Elapsed time: 9 000 ms (≈ 9 s)
• Replication factor: 1 (no replication)

How to run

# 1. Download TigerBeetle:

curl -Lo tigerbeetle.zip https://mac.tigerbeetle.com && unzip tigerbeetle.zip ./tigerbeetle version

# 2. Set the config of the database like cluster, replica
./tigerbeetle format --cluster=0 --replica=0 --replica-count=1 --development ./0_0.tigerbeetle

# 3. Run TigerBeetle

./tigerbeetle start --addresses=3000 --development ./0_0.tigerbeetle

# 3. Execute the benchmark JAR:
java -jar target/DatabaseBenchmarks-1.0.0.jar
