Realtime Client Database: gRPC Bi-Directional Streams and ZIO Hub

6 minute read

, ,

Realtime push-based databases such as Google Firebase conveniently ensure clients are synchronized with the server. Data updates stream to clients immediately as they happen; and if a client disconnects, updates are immediately processed after reconnecting. gRPC server streaming and ZIO Hub can implement this functionality replicating an expensive paid Firebase service while allowing greater extensibility.

Realtime Client Database: External Datasource using ZIO ZLayer

2 minute read

, ,

Expanding on the realtime Firebase implementation in the previous article, this expands the functionality allowing the server to fetch data on-demand from an external datasource. Additionally, functionality to periodical refresh active data which is subscribed to by connected clients transforms this database into an efficient cache to evolving external data which can only be obtained by polling.

Job Queue Execution Management using ZIO Scopes

11 minute read

, ,

Job Queues are critical parts of Enterprise workloads. Complex queues use distributed nodes, state machines, and complex scheduling to trigger and track running jobs. But when simplicity allows the best approach is to create small idempotent jobs. The smaller the unit of work the easier progress can be tracked, jobs can be restarted or rerun with minimal waste, composability and reuse are increased, and logic is easier to reason about. These are the same arguments for Functional Programming and their Effect Systems, such as ZIO. Effect systems are congruent to the enterprise job queue, with ZIO fibers performing work and ZIO Resource Management forming the scheduling and supervision backbone. An efficient job queue can be written using ZIO constructs using surprisingly minimal amount of code.
