# CRDTs in a Nutshell
|
||||
|
||||
## Motivations
|
||||
|
||||
+ **Eventual Consistency** for scalability
|
||||
|
||||
+ Improve theoretical grounding
|
||||
|
||||
+ Weaken coordination requirements
|
||||
|
||||
## Eventual Consistency
|
||||
|
||||
+ Updates are executed at replicas
|
||||
|
||||
+ Later, sent to all other replicas
|
||||
|
||||
+ Eventually, all replicas see all updates
|
||||
|
||||
+ They apply asynchronously and possibly in different orders
|
||||
|
||||
+ Concurrent updates may conflict and require *arbitration*
|
||||
|
||||
## Strong Eventual Consistency
|
||||
|
||||
+ Formal model of Eventual Consistency
|
||||
|
||||
+ No conflict-resolution or roll-back required; *Conflict-Freedom*
|
||||
|
||||
+ Extremely scalable and fault-tolerant
|
||||
|
||||
+ Based on mathematical properties
|
||||
|
||||
## Two Related Formulations
|
||||
|
||||
+ *Convergent* Replicated Data Types (CvRDT)
|
||||
|
||||
- State-based
|
||||
- Weak network requirements
|
||||
- Based on *monotonic join semilattices*
|
||||
|
||||
+ *Commutative* Replicated Data Types (CmRDT)
|
||||
|
||||
- Operation-based
|
||||
- Requires reliable broadcast with *delivery order*
|
||||
- Based on *commutativity of concurrent operations*
|
||||
|
||||
+ Both can always simulate one another
|
||||
|
||||
# System Model of CRDTs
|
||||
|
||||
## Distributed Systems
|
||||
|
||||
+ Processes interconnected by asynchronous network
|
||||
+ Network can partition and recover
|
||||
+ Nodes can operate disconnected for some time
|
||||
+ Processes may crash and recover, memory survives crashes
|
||||
+ Assumption of non-Byzantine behavior
|
||||
|
||||
## Atoms and Objects
|
||||
|
||||
+ Processes store **atoms** and **objects**
|
||||
+ Atoms are base immutable data; directly comparable values
|
||||
+ Objects are mutable, replicated data; collections of objects and atoms
|
||||
+ Objects with the same identity but different location are **replicas**
|
||||
+ Objects are independent; no transactions
|
||||
|
||||
## Operations
|
||||
|
||||
+ There are **clients** that query and modify objects via **operations**
|
||||
|
||||
+ A client acts on one replica, the **source** replica
|
||||
|
||||
+ The operation executes locally at the source and then remotely
|
||||
- *Phase 1*: Operation called at source; possibly some processing occurs
|
||||
- *Phase 2*: Update transmitted asynchronously to **downstream** replicas
|
||||
|
||||
## State-Based Replication
|
||||
|
||||
+ Update happens entirely at source replica via **update**
|
||||
+ Modified payload transmitted downstream
|
||||
+ Receivers use **merge** operation to update their payload
|
||||
+ Replicas can be compared via **compare** operation
|
||||
+ Operations guarded by **source pre-conditions**
|
||||
|
||||
## State-Based Causal History Model
|
||||
|
||||
+ Initially, set $C(x_i)$ of each replica $x_i$ is $\emptyset$
|
||||
+ After update $f$, $C(f(x_i))$ is $C(x_i) \cup \{f\}$
|
||||
+ After merge of $C(x_i)$ and $C(x_j)$, the state is $C(x_i) \cup C(x_j)$
|
||||
+ The "happens-before" relation $f \to g \Leftrightarrow C(f) \subset C(g)$
|
||||
|
||||
## State-Based Network Assumptions
|
||||
|
||||
+ States transmit between replicas at unspecified times
|
||||
|
||||
+ Transmissions occur infinitely often
|
||||
|
||||
+ Communication forms a connected graph
|
||||
|
||||
## Operation-Based Replication
|
||||
|
||||
+ Phase 1 of **update** is local to source replica
|
||||
- Precondition guard must be true
|
||||
- Executes immediately and atomically
|
||||
- No side-effects
|
||||
- May return results
|
||||
+ Phase 2 of **update** executes asynchronously on downstream replicas
|
||||
- Downstream precondition must be true
|
||||
- Can't return results
|
||||
- Updates downstream state
|
||||
- Arguments prepared by Phase 1
|
||||
- Executes atomically
|
||||
|
||||
## Operation-Based Causal History Model
|
||||
|
||||
+ Initially, set $C(x_i)$ of each replica $x_i$ is $\emptyset$
|
||||
+ After downstream phase, $f$, $C(f(x_i))$ is $C(x_i) \cup \{f\}$
|
||||
+ The "happens-before" relation $f \to g \Leftrightarrow C(f) \subset C(g)$
|
||||
+ **causal delivery** means that if $f \to g$, then $f$ is delivered before $g$
|
||||
|
||||
## Operation-Based Network Assumptions
|
||||
|
||||
+ Presence of a reliable broadcast mechanism
|
||||
+ Delivery of every update in a **delivery order**
|
||||
+ The delivery order maintains downstream preconditions
|
||||
+ A delivery order of causal delivery is always sufficient
|
||||
|
||||
## Definition of Convergence
|
||||
|
||||
+ Two replicas $x_i$ and $x_j$ of $x$ *converge eventually* if:
|
||||
|
||||
- Safety: $\forall{i,j}: C(x_i) = C(x_j)$ implies payloads of $i$ and $j$ are equivalent
|
||||
|
||||
- Liveness: $\forall{i,j}: f \in C(x_i)$ implies *eventually* $f \in C(x_j)$
|
||||
|
||||
+ States are equivalent when all **query** operations return the same values
|
||||
|
||||
## Convergent Replicated Data Type (CvRDT)
|
||||
|
||||
+ Based on concept of **join semilattice**
|
||||
|
||||
- A *set* of values equipped with
|
||||
- a *partial order* relation ($\leq$ or $\sqsubseteq$) on them
|
||||
- and a *least upper bound* (LUB or $\sqcup$) operation, aka *join*
|
||||
|
||||
+ LUB: if $m = x \sqcup y$ then $m$ is a LUB under $\leq$ **iff**
|
||||
|
||||
- $x \leq m \land y \leq m$
|
||||
- There is no $m' \leq m$ where $x \leq m' \land y \leq m'$
|
||||
- The "smallest" $m$ in the set that is "at least as big" as both $x$ and $y$
|
||||
- LUB is *commutative*, *idempotent*, and *associative*
|
||||
|
||||
+ An *ordered set* is a *join semilattice* if for all pairs, a LUB exists
|
||||
|
||||
+ For CvRDTs, **merge** is the LUB operation on the payloads
|
||||
|
||||
+ All operations are *non-decreasing* with respect to the ordering
|
||||
|
||||
## Example CvRDT
|
||||
|
||||
+ An integer counter; our set is $\mathbb{Z}$
|
||||
+ Our ordering is numeric $\leq$
|
||||
+ For merge, we use $max()$
|
||||
+ Our payload, `x`, is initialized to `0`
|
||||
+ Operation **value** returning an integer $j$ is `let j = x`
|
||||
+ Operation **compare(a,b)** is `a.x ` $\leq$ ` b.x`
|
||||
+ Operation **inc** is `x := x + 1`
|
||||
+ Operation **merge(a,b)** is `max(a,b)`
|
||||
|
||||
## Commutative Replicated Data Type (CmRDT)
|
||||
|
||||
+ Based on a reliable broadcast strong enough to guarantee **delivery order**
|
||||
+ **Delivery order**, $<$, is specified per CmRDT
|
||||
+ Some operations are not ordered; they are *concurrent*, $\|$
|
||||
+ $f \| g \Leftrightarrow f \nless g \land g \nless f$
|
||||
+ All replicas converge to the same state when:
|
||||
- all concurrent operations commute, so
|
||||
- all execution orders consistent with delivery order are equivalent
|
||||
+ Reliable causal delivery
|
||||
- doesn't require agreement
|
||||
- is immune to partitioning (connected subsets still make deliveries)
|
||||
- eventually delivers all updates to all nodes
|
||||
+ Delivery order is never stricter than causal delivery
|
||||
|
||||
## Relationship of CvRDT and CmRDT
|
||||
|
||||
+ State-based CvRDT are:
|
||||
- easy to reason about (relatively)
|
||||
- requires only weak network properties, no membership tracking
|
||||
- may be inefficient for large objects
|
||||
- used in NFS, AFS, Coda, Dynamo, Riak
|
||||
+ Operation-based CmRDT are:
|
||||
- harder to reason about; requires reasoning about history
|
||||
- have greater expressive power
|
||||
- require an underlying reliable broadcast protocol, need membership tracking
|
||||
- used in Bayou, Rover, IceCube, Telex
|
||||
+ They can always emulate one another (although not necessarily efficiently)
