Needs advice

Hello everyone, I am searching for the appropriate solution for a financial use case. I want to handle user balancing in a distributed way. I did a little research and have found YugabyteDB as a solution that offers distributed ACID. Although, I have also found that Scylla seems great in terms of TPS. So I wonder which solutions fit better, or maybe there is another great option I am not considering.

Please guys, what do you think?

At Pushnami we were using Redis for quite a long time, and still do for disposable caches. However as we continued to grow, we started to feel limitations of keeping data sets in memory, and only being able to use 1 CPU per server. We started to look around. Our requirements were pretty clear: - Very fast reads and writes (sub ms) - Ability to hold Terabytes of data - Ability to horizontally scale - Strong support for TTL and data eviction After looking at several alternatives we decided on Scylla , which had familiar Cassandra interface but claimed to be much faster. 2 years later - we run a cluster of 6 nodes that holds over 20 TB of data, and performs 150,000 operations per second. I would say pretty impressive! It was also easy to get started on AWS, as ScyllaDB provides prebuilt AMI with optimal configurations baked in.

ScyllaDB Alternatives & Comparisons

What are some alternatives to ScyllaDB?
Partitioning means that Cassandra can distribute your data across multiple machines in an application-transparent matter. Cassandra will automatically repartition as machines are added and removed from the cluster. Row store means that like relational databases, Cassandra organizes data by rows and columns. The Cassandra Query Language (CQL) is a close relative of SQL.
Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.
Aerospike is an open-source, modern database built from the ground up to push the limits of flash storage, processors and networks. It was designed to operate with predictable low latency at high throughput with uncompromising reliability – both high availability and ACID guarantees.
MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
It supports JPEG, PNG and GIF files. You can optimize your images in two ways - by providing an URL of the image you want to optimize or by uploading an image file directly to its API.
