To my understanding, strong consistency can be achieved when Vr + Vw > V. Vr is the read quorum (Vr), Vw is the write quorum. Assume V = 3. When w ...
This is the pseudocode of A* from wiki (https://en.wikipedia.org/wiki/A*_search_algorithm): I was wondering if this algorithm is assuming that the ...
On Wikipedia, the construction of a Huffman tree is described as such: The simplest construction algorithm uses a priority queue where the node wi ...
having a simple ordinary model like this works for my case but as there's only up to 1 active order at the same time, keeping it consistent is a ch ...
Hi everyone, I'm a little bit lost with a problem thinking in ddd way. Imagine you have an application to sell concert ticket. So you have an entity ...
I am trying to improve my knowledge in distributed databases and the various levels of consistency that could be achieved. First, let me define some t ...
Hi everyone, I don't see why when we are talking about concurrency in DDD with aggregates, we don't force it with the incremental database feature (w ...
Many distributed systems (e.g. databases) say they can provide strong consistency. For example, assuming N replicas of the data, a requirement that W ...
The definition of cache coherence says that: A read must return the most recent write. Every write must eventually be accessible via a read. W ...
I am attempting to prevent usage of the default schema of "dbo" in my SQL Server databases. This is being applied to an existing long term project wit ...
I have a question regarding the WAL + memtable writes in Cassandra. By default until WAL and memtable are both updated, Cassandra doesn't mark the wri ...
I was reading through docs and encountered this part: Consistency Level Quorum Reads Quorum Writes ...
I am developing some concurrent algorithms which deal with Reference objects. I am using java 17. The thing is I don't know what's the memory semanti ...
Let's say there is a DynamoDB key with a value of 0, and there is a process that repeatably reads from this key using eventually consistent reads. Whi ...
We have a three-node Couchbase cluster with two replicas and durability level MAJORITY. This means that the mutation will be replicated to the active ...
Let's say I have this generic saga scenario (given three distinct microservices A, B, and C, communicating with messaging): It is my understanding ...
I have a spark dataframe with around 43 million records, which i'm trying to write to a Mongo Collection. When I write it to a unsharded collection, t ...
I'd like to express: "insertion of record with 'parent' value that is not included in 'rowid' AFTER INSERTION is forbidden." My intention is to keep ...
I've a question about x86 TSO memory consistency model. Starting from 'A primer on Memory Consistency and Cache Coherence' it seems to me that the 'gl ...
