Is Neo4j eventually consistent?
Eventual Consistency Features. Eventual consistency is a consistency model that guarantees that, if no new updates are made to a given object, eventually all accesses to that object will return the last updated value. This section describes the mechanisms provided for eventual consistency in Neo4j.
Does Neo4j support ACID properties?
ACID properties − Neo4j supports full ACID (Atomicity, Consistency, Isolation, and Durability) rules. Scalability and reliability − You can scale the database by increasing the number of reads/writes, and the volume without effecting the query processing speed and data integrity.
Does database always require ACID compliance?
To have optimal transaction control, a database system must be ACID compliant, which stands for the following properties: Atomicity, Consistency, Isolation, Durability. The definitions of the ACID properties are: Atomicity: A transaction must be completed in its entirety or not at all.
Does MongoDB support ACID?
MongoDB, has always supported ACID transactions in a single document and, when leveraging the document model appropriately, many applications don’t need ACID guarantees across multiple documents. ACID guarantees across documents simplify application logic needed to satisfy complex applications.
Why is NoSQL not consistent?
To answer the actual question directly: “Why are nosql databases not acid compliant” is because they weren’t designed to be. ACID is a lot of work and requries lots of resources in the machine, but even Google are being forced to go back to ACID and SQL!
What does consistent mean in acid?
Consistency refers to maintaining data integrity constraints. A consistent transaction will not violate integrity constraints placed on the data by the database rules. This ensures changes are successful at maintaining data integrity or they are canceled completely.
Is eventual consistency part of acid?
Eventually-consistent services are often classified as providing BASE semantics (basically-available, soft-state, eventual consistency), in contrast to traditional ACID (atomicity, consistency, isolation, durability). In chemistry, a base is the opposite of an acid, which helps in remembering the acronym.
Why MongoDB is not ACID compliant?
This is because, unless you specifically made this a mongodb atomic operation, the operation is not guaranteed to have been atomic.
What is eventual consistency in MongoDB?

What configuration options are available for Neo4j streams?
Any configuration option that starts with kafka. will be passed to the underlying Kafka driver. Neo4j streams uses the official Confluent Kafka producer and consumer java clients. Configuration settings which are valid for those connectors will also work for Neo4j Streams.
What configuration settings should I use for Kafka In Neo4j?
For example, in the Kafka documentation linked below, the configuration setting named batch.size should be stated as kafka.batch.size in Neo4j Streams. The following are common configuration settings you may wish to use. This is not a complete list.
