What is Apache bRPC?

Apache bRPC keeps widening what it can talk to and what it can run on.

bRPC ships a feature release roughly every three months with a consistent shape: a handful of protocol or transport capabilities, a long bugfix list, and steady work on RDMA. Recent releases added native Redis Cluster channel support, a transport layer for protocol extensions, RDMA ECE, SingleIOBuf for FlatBuffers serialisation, RISC-V architecture support, Couchbase CRUD operations, and rate-limited backup request policies. Protobuf compatibility is refreshed almost every cycle, now through v34.

What is pgBackRest?

pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.

pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.

Apache bRPC vs pgBackRest: editorial side-by-side

A0.0

Apache bRPC keeps widening what it can talk to and what it can run on.

◆ Current state

bRPC ships a feature release roughly every three months with a consistent shape: a handful of protocol or transport capabilities, a long bugfix list, and steady work on RDMA. Recent releases added native Redis Cluster channel support, a transport layer for protocol extensions, RDMA ECE, SingleIOBuf for FlatBuffers serialisation, RISC-V architecture support, Couchbase CRUD operations, and rate-limited backup request policies. Protobuf compatibility is refreshed almost every cycle, now through v34.

◆ Where it's heading

Two directions run together. One is reach: more architectures, more backends, more wire protocols, so bRPC can be the single client library inside a heterogeneous fleet. The other is the low-latency path, where RDMA has received polling mode, dynamic block pool expansion and now ECE support across four consecutive releases. The debugging work — bthread naming, configurable stack trace signals, AddressSanitizer support — suggests the users pushing hardest are the ones running it at scale.

◆ Prediction

RDMA has drawn work in every recent release and is the most likely place for the next feature, alongside another Protobuf compatibility refresh.

P5.0

pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.

◆ Current state

pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.

◆ Where it's heading

Two currents continue. Support for the next PostgreSQL major arrives experimentally a full release before it is needed — 18 in 2.55.0, 19 in 2.59.0, and now tracking 19's betas point by point — so the backup tool is ready before the database ships. The second is a move away from ambient privilege and toward cloud-native identity: managed identities and pod identity in place of stored keys, and the root restriction narrowing what a compromised invocation can reach. The 2.59.1 fixes are the ordinary cost of that pace, including a packaging fault in the GitHub source archives.

◆ Prediction

Expect the beta-tracking patches to continue through PostgreSQL 19's release cycle, with the next feature release arriving after 19 goes final rather than before it.
