TigerBeetle: High-Performance Financial Database for OLTP Workloads

March 10, 2026

What is TigerBeetle?

TigerBeetle is a purpose-built financial accounting database designed specifically for Online Transaction Processing (OLTP) workloads. Unlike general-purpose databases like PostgreSQL or MySQL, TigerBeetle is architected from the ground up to handle the unique challenges of financial transactions at scale.

Built in Zig for maximum performance, TigerBeetle uses a debit-credit accounting model and provides strong consistency guarantees through distributed consensus. It's designed to process up to 1 million transactions per second while maintaining strict safety and durability requirements.

The Debit-Credit Model: Centuries of Proven Accounting

TigerBeetle uses double-entry bookkeeping model that captures the "who, what, when, where, why, and how much" of every transaction.

Core Principles

Understanding Financial Account Types

TigerBeetle implements the five fundamental account types from classical accounting. Understanding these types is crucial for proper data modeling.

The Five Account Types

1. Asset Accounts

Definition: What you own that could produce income or be sold.

Examples:

Balance calculation: balance = debits - credits

TigerBeetle flag: credits_must_not_exceed_debits (prevents negative balances)

2. Liability Accounts

Definition: What you owe to other people or entities.

Examples:

Balance calculation: balance = credits - debits

TigerBeetle flag: debits_must_not_exceed_credits (prevents negative balances)

3. Equity Accounts

Definition: The residual value owned by shareholders after deducting liabilities.

Examples:

Balance calculation: balance = credits - debits

4. Income Accounts

Definition: Increases in assets or decreases in liabilities that increase equity.

Examples:

Balance calculation: balance = credits - debits

5. Expense Accounts

Definition: Decreases in assets or increases in liabilities that decrease equity.

Examples:

Balance calculation: balance = debits - credits

The Accounting Equation

All five account types maintain this fundamental equation:

Assets - Liabilities = Equity + Income - Expenses

Every transaction involves at least one debit and one credit, ensuring both sides of the equation remain balanced.

Debits and Credits Explained

Unlike intuitive "positive/negative" systems, accounting uses debits and credits based on account type:

Account Type Debit Effect Credit Effect
Asset Increases balance Decreases balance
Liability Decreases balance Increases balance
Equity Decreases balance Increases balance
Income Decreases balance Increases balance
Expense Increases balance Decreases balance

Real-World Example: User Makes a Purchase

When a user pays $100 to a merchant:

Transfer 1:
  debit_account_id: user_cash_account (Asset)      # Decreases user's cash
  credit_account_id: merchant_cash_account (Asset) # Increases merchant's cash
  amount: 10000 # $100.00 in cents

Transfer 2 (merchant records revenue):
  debit_account_id: merchant_cash_account (Asset)  # Cash received
  credit_account_id: merchant_revenue (Income)     # Records income
  amount: 10000

Perspective Matters

The same financial instrument appears as different account types depending on perspective:

TigerBeetle's Data Model

TigerBeetle enforces the debit-credit schema natively with each transfer capturing:

Handling Fractional Amounts

TigerBeetle stores amounts as unsigned 128-bit integers. To represent fractional currencies, map the smallest useful unit to 1.

Asset scale expresses this as a power of 10:

Important: Asset scales cannot be changed after account creation due to immutability constraints.

Compound Transfers: Multi-Party Transactions

While TigerBeetle's core transfer model supports single debit/single credit for maximum performance, real-world scenarios often require multi-party transactions. TigerBeetle provides patterns for implementing these using linked events.

Linked Events for Atomicity

The flags.linked property creates chains of transfers that succeed or fail together as an atomic unit. When a transfer has the linked flag set, it connects to the next transfer in the request. If any transfer in the chain fails, all transfers in that chain fail.

// Example: Three linked transfers (A, B, C)
// All three succeed together or all three fail together
Transfer A: { ..., flags: [:linked] }
Transfer B: { ..., flags: [:linked] }
Transfer C: { ..., flags: [] } // Last one terminates the chain

Pattern 1: One-to-Many Transfers

Scenario: Split a single payment across multiple recipients (e.g., splitting tips, revenue sharing).

defmodule PaymentSystem.CompoundTransfers do
  # Split $100 from user to three recipients ($50, $30, $20)
  def split_payment(user_account, recipients_and_amounts) do
    transfers = recipients_and_amounts
    |> Enum.with_index()
    |> Enum.map(fn {{recipient_account, amount}, index} ->
      is_last = index == length(recipients_and_amounts) - 1

      %{
        id: generate_transfer_id(),
        debit_account_id: user_account,
        credit_account_id: recipient_account,
        amount: amount,
        ledger: @ledger_usd,
        code: @code_split_payment,
        flags: if(is_last, do: [], else: [:linked])
      }
    end)

    TigerBeetle.create_transfers(transfers)
  end
end

# Usage
split_payment(user_wallet, [
  {recipient_1, 5000}, # $50.00
  {recipient_2, 3000}, # $30.00
  {recipient_3, 2000}  # $20.00
])

Pattern 2: Many-to-One Transfers

Scenario: Collect funds from multiple sources into one account (e.g., collecting fees, pooling funds).

# Collect $10 fee from 5 different users into platform account
def collect_fees(user_accounts, platform_account, fee_amount) do
  transfers = user_accounts
  |> Enum.with_index()
  |> Enum.map(fn {user_account, index} ->
    is_last = index == length(user_accounts) - 1

    %{
      id: generate_transfer_id(),
      debit_account_id: user_account,
      credit_account_id: platform_account,
      amount: fee_amount,
      ledger: @ledger_usd,
      code: @code_platform_fee,
      flags: if(is_last, do: [], else: [:linked])
    }
  end)

  TigerBeetle.create_transfers(transfers)
end

Pattern 3: Many-to-Many with Control Account

For complex scenarios with multiple debits and multiple credits, use an intermediary control account:

# Transfer funds from 3 users to 2 merchants (e.g., group purchase)
def group_purchase(buyer_accounts, seller_accounts, control_account) do
  # Phase 1: Debit all buyers to control account (linked)
  buyer_transfers = buyer_accounts
  |> Enum.with_index()
  |> Enum.map(fn {{account, amount}, index} ->
    %{
      id: generate_transfer_id(),
      debit_account_id: account,
      credit_account_id: control_account,
      amount: amount,
      ledger: @ledger_usd,
      code: @code_group_purchase,
      flags: [:linked] # All buyer transfers are linked
    }
  end)

  # Phase 2: Credit all sellers from control account (linked)
  seller_transfers = seller_accounts
  |> Enum.with_index()
  |> Enum.map(fn {{account, amount}, index} ->
    is_last = index == length(seller_accounts) - 1

    %{
      id: generate_transfer_id(),
      debit_account_id: control_account,
      credit_account_id: account,
      amount: amount,
      ledger: @ledger_usd,
      code: @code_group_purchase,
      flags: if(is_last, do: [], else: [:linked])
    }
  end)

  all_transfers = buyer_transfers ++ seller_transfers
  TigerBeetle.create_transfers(all_transfers)
end

Balancing Transfers

TigerBeetle provides special flags for conditional transfers based on available balance:

# Drain all available funds from an account
%{
  id: generate_transfer_id(),
  debit_account_id: source_account,
  credit_account_id: destination_account,
  amount: 0, # Will be calculated based on available balance
  ledger: @ledger_usd,
  code: @code_account_closure,
  flags: [:balancing_debit]
}

Performance: Built for Speed

TigerBeetle achieves exceptional performance through multiple design decisions:

1. Interface Designed for OLTP

Unlike traditional databases where business logic lives in the application, TigerBeetle embeds the accounting logic inside the database. Applications speak debit-credit directly without translating to SQL. This eliminates expensive network locks and round trips.

2. Pervasive Batching

TigerBeetle processes batches of up to 8,190 transfers per request. The cost of replication through consensus is paid once per batch, making it nearly as fast as an in-memory hash map while providing extreme durability.

Under light load, batches automatically shrink to trade unnecessary throughput for better latency.

3. Extreme Engineering

Why Single-Threaded?

Financial databases are notoriously difficult to shard because:

TigerBeetle provides strong consistency without row locks, sidestepping contention issues entirely. The single-core design with extreme optimizations delivers higher throughput than multi-threaded approaches.

Safety and Reliability

TigerBeetle provides enterprise-grade safety guarantees essential for financial systems:

Distributed Consensus

TigerBeetle uses a consensus algorithm to replicate data across multiple nodes. This provides:

Immutability

Unlike SQL databases with UPDATE and DELETE, TigerBeetle enforces append-only immutability. Transfers cannot be modified or deleted, ensuring:

Real-World Example: Payment Processing System with Elixir

Let's build a practical payment processing system that handles user wallets, merchant payments, and platform fees using TigerBeetle and Elixir.

Designing the Account Structure

Before coding, let's design our account structure using the five account types. This is a critical step in any TigerBeetle implementation.

For a Payment Platform (e.g., Stripe-like service)

Account Type Flag Purpose
User Wallet Asset credits_must_not_exceed_debits User's cash balance (what they own)
Merchant Account Asset credits_must_not_exceed_debits Merchant's receivable funds
Platform Revenue Income debits_must_not_exceed_credits Platform's fee income
User Liability (Bank View) Liability debits_must_not_exceed_credits What platform owes to users (bank perspective)
Operating Expenses Expense credits_must_not_exceed_debits Platform operational costs

Example Transaction Flow

When a user pays $100 to a merchant with a $2.50 platform fee:

# Step 1: Debit user wallet (Asset decreases)
Transfer 1:
  debit_account_id: user_wallet (Asset)
  credit_account_id: merchant_account (Asset)
  amount: 9750 # $97.50 to merchant

# Step 2: Collect platform fee (Income increases)
Transfer 2:
  debit_account_id: user_wallet (Asset)
  credit_account_id: platform_revenue (Income)
  amount: 250 # $2.50 fee

# These can be linked for atomicity
transfers = [
  %{..., flags: [:linked]},  # Merchant payment
  %{..., flags: []}          # Platform fee
]

Two-Phase Transfers: Authorization and Settlement

TigerBeetle implements two-phase transfers, inspired by the two-phase commit protocol used in distributed transactions. This pattern separates fund reservation (authorization) from fund movement (settlement).

How Two-Phase Transfers Work

Phase 1: Reserve Funds (Pending Transfer)

Create a transfer with flags.pending. This reserves the amount in the accounts' debits_pending and credits_pending fields without affecting the posted balance.

pending_transfer = %{
  id: transfer_id,
  debit_account_id: user_wallet,
  credit_account_id: merchant_account,
  amount: 10000, # $100.00
  ledger: @ledger_usd,
  code: @code_payment,
  flags: [:pending],
  timeout: 3600 # Optional: auto-void after 1 hour
}

Phase 2: Resolve Funds (Post, Void, or Expire)

You have three options to resolve a pending transfer:

1. Post (Capture): Move funds to destination

post_transfer = %{
  id: new_transfer_id,
  pending_id: transfer_id, # Reference to pending transfer
  amount: 10000, # Can post partial amount or full amount
  flags: [:post_pending_transfer]
  # Other fields can be 0 or match the pending transfer
}

2. Void (Cancel): Return funds to original account

void_transfer = %{
  id: new_transfer_id,
  pending_id: transfer_id,
  flags: [:void_pending_transfer]
  # Amount and accounts are ignored
}

3. Expire (Automatic): If timeout is set and elapses, funds automatically return
