The architecture retains reusable task specifications, data schemas, tool configurations, and output constraints while discarding session-specific reasoning traces. Shared workspaces support role-based collaborative reuse, and experiments report higher task completion than no memory or full-history persistence, along with zero-token data refresh and lower token costs. ### Source excerpt Agentic LLM systems that generate code through multi-turn tool use face a fundamental context problem: each session starts from zero, discarding the configuration choices, domain constraints, data schemas, and tool-use patterns that made previous sessions productive. Naively persisting entire conversation histories is both token-inefficient and counterproductive--irrelevant context degrades generation quality. We introduce shared selective persistent memory, a memory architecture for agentic systems that identifies and retains four categories of reusable context--task specifications, data... ## Introducing TIN: full-text search for Postgres DevFeed: [Introducing TIN: full-text search for Postgres]() Original publisher: [Read original article]() Author: Patrick Reynolds Published: 2026-09-16T00:00:00Z Content type: release Language: en Sources: [Blog -- PlanetScale]() Topics: [Databases](), [benchmarking]() Tags: [backups](), [benchmark](), [benchmarks](), [bm25](), [engineering](), [full-text-search](), [index](), [performance](), [postgres](), [reddit](), [replication](), [search](), [text](), [wikipedia]() ### AI overview PlanetScale announces TIN, a full-text search extension for Postgres and Neki databases.

It's how users sign in, access services, and engage with your applications. As your business scales across geographies, ensuring authentication is always available becomes a core architectural requirement. However, building multi-Region authentication has traditionally required complex custom replication solutions that [...] ## Replica-aware routing public beta DevFeed: [Replica-aware routing public beta]() Original publisher: [Read original article]() Author: Amy Chen; Jan Mensch Published: 2026-09-15T13:15:00Z Content type: release Language: en Sources: [ClickHouse Blog]() Topics: [clickhouse](), [Routing (disambiguation)](), [Replication](), [Caching]() Tags: [cache](), [clickhouse](), [consistency](), [replication](), [routing]() ### AI overview ClickHouse introduces replica-aware routing in Public Beta for Enterprise customers. The feature routes requests to the same replica, allowing continued access to temporary tables and named sessions and supporting read-after-write consistency over HTTP or the native protocol. ### Source excerpt Temporary tables and named sessions live on a single ClickHouse replica, so a follow-up query routed elsewhere can't see them. Replica-aware routing pins your requests to the same replica over HTTP or the native protocol -- and here's how we built it. ## Percona and HexaCluster: Faster, Safer Oracle Migration DevFeed: [Percona and HexaCluster: Faster, Safer Oracle Migration]() Original publisher: [Read original article]() Author: Percona Team Published: 2026-09-14T22:19:16Z Content type: article Language: en Sources: [Blog - Percona]() Topics: [Oracle Database](), [migration](), [Open Source](), [PostgreSQL](), [Database Migration](), [Replication](), [Tooling]() Tags: [database](), [database-migration](), [database-trends](), [engineering](), [insight-for-dbas](), [insight-for-developers](), [migration](), [open-source](), [oracle](), [partners](), [percona](), [postgresql](), [replication](), [schema](), [sql](), [tooling](), [validation]() ### AI overview Percona and HexaCluster describe a partnership for moving organizations from Oracle, SQL Server, DB2, and Sybase ASE to supported open source databases, primarily PostgreSQL.

Using Galera's socket.dynamic option, operators can perform two rolling restarts: first allowing encrypted and plaintext connections, then enforcing TLS-only communication. ### Source excerpt Starting with Percona XtraDB Cluster (PXC) 8.0, replication traffic encryption is enabled by default. That said, it's common to find clusters running without TLS that suddenly need it: a new compliance requirement, an audit finding, a network segment that is no longer considered trusted. PXC has a variable for exactly that case, pxc-encrypt-cluster-traffic, which handles ...

It compares byte lag with time lag, explains why idle systems can hide failures, and discusses replay delays caused by write bursts and long-running replica queries. ### Source excerpt Byte lag between primary and replica reads zero on an idle primary even when replication is completely stuck, so the metric that looks healthiest is the one that hides the failure. Time lag measured from the last replayed transaction is the signal that stays honest. Adding a read replica silently removes read-your-writes, which means any flow that writes and then reads back needs either primary routing or an explicit wait for the replica to reach that write's log position. ## Introducing Neon Labs DevFeed: [Introducing Neon Labs]() Original publisher: [Read original article]() Author: Savannah Longoria Published: 2026-08-26T12:00:00Z Content type: release Language: en Sources: [Blog -- Neon Docs]() Topics: [migration](), [Databases](), [Replication](), [Transactions](), [Availability]() Tags: [agent](), [availability](), [database](), [migration](), [playground](), [postgres](), [product](), [replication](), [tools](), [transactions]() ### AI overview Neon Labs is a new home for experimental tools built around Lakebase Postgres.
