I'm looking for 3rdparty service in order to create/emulate something similar to a Postgres sequence database object.
I need this thread safe functionality in order to be able to ask it for next, unique
Longvalue. I'm going to use this value as a surrogate key for my Spring Boot/Neoj4 application entities.The main criterion is a speed. It should be pretty fast and durable(not only in memory but also persisted to HDD in order to survive after crashes and restarts)
Also, I don't want to go with
UUIDbecause I have to expose these IDs within my web application url parameters and in case ofUUIDmy urls look awful. I want to go with a plain Long values for IDs.Could you please suggest some database/service/technology that can be installed on my server and called for the unique IDs ?
UPDATED
Is it possible to implement fault-tolerant(persisted) AtomicLong sequence with Apache ZooKeeper or Hazelcast ? If so, is there any open source implementation of this solution that can be downloaded and used?
