What it does
Session relational database persistence.
Unverified — not yet verified
Session relational database persistence. Not yet verified — install and test it yourself.
“Unverified” means our automated CI has not yet installed this plugin. Feature descriptions and version compatibility are the author’s claims. This is not a security audit and not an endorsement of third-party code.
README
@morlay/session-persistence-rdb
RDB(SQLite / PostgreSQL)持久会话后端(ctx.sessionPersistence):通过 drizzle
实现 PersistenceBackend<number>,复用上游 PersistenceCoordinator 与契约测试套件,
支持配置选择 SQLite 或 PostgreSQL 后端。设计细节(表结构、delta 过滤、并发写、
方言差异、仓库结构)见 docs/design.md。
安装
包发布在 GitHub Packages,按包名安装到 dsh profile(示例:web;dsh plugin add 把参数原样转发给 pnpm,版本号按发布版本调整)。registry 必须限定在@morlay scope(--config.@morlay:registry=…),不要用全局 --registry,
否则依赖(@deepseek-ai/* 等)也会被指到 GitHub Packages 而解析失败:
dsh plugin --profile=web add "@morlay/session-persistence-rdb@^0.0.1" --config.@morlay:registry=https://npm.pkg.github.com/
GitHub Packages 的 registry 要求认证(公开包也一样):profile 的 .npmrc
需为 npm.pkg.github.com 配置访问 token(如//npm.pkg.github.com/:_authToken=<token>),详见
GitHub 文档。
配置
配置写在 ${DSH_HOME}/settings.yaml,settings namespace 为插件短名session-persistence-rdb(与 cordis 插件 name 一致):
session-persistence-rdb:
type: sqlite
# path 省略时回落 cordis.patch.yml 的默认($DSH_HOME/sessions/sessions.sqlite,
# 由 bundle patch 的 !!js 表达式求值);自定义路径请用绝对路径字符串。
path: /absolute/path/to/sessions.sqlite
journalMode: wal
busyTimeout: 5000
settings.yaml 是纯 YAML(settings-local 用
yaml库解析),不支持!!js
JS 表达式——!!js dshHomePath(...)会被当作字面字符串。!!js只在cordis.patch.yml(bundle patch 层,loader 求值)有效。
字段即 Config 判别联合(见下);未写出的字段回落到 bundle patch / cordis.yml 的
config 默认值。PostgreSQL:
session-persistence-rdb:
type: postgres
connectionString: postgres://user:pass@localhost:5432/sessions
Config 类型:
type Config =
| {
type: "sqlite";
/** SQLite 数据库文件路径;`:memory:` 用于测试。 */
path: string;
/** journal_mode:`wal`(默认)/ `delete` / `truncate` / `persist`。 */
journalMode?: "wal" | "delete" | "truncate" | "persist";
/** 写锁竞争等待毫秒数(默认 5000)。 */
busyTimeout?: number;
}
| {
type: "postgres";
/** node-postgres 连接串;首次打开自动建表并写入 store 身份。 */
connectionString: string;
};
Install
Install the catalog once, then DeepSeek Harness can find and install any plugin from this site automatically:
dsh plugin add dshbase-catalog Then say "install session-persistence-rdb for me" — your agent finds it in the directory and installs it. Docs: dshbase-catalog · verified packs.
This plugin is GitHub source (not published to npm) — install it straight from the repo:
Web profile:
dsh plugin --profile web add github:morlay/session-persistence-rdb Headless (CLI) profile:
dsh plugin --profile headless add github:morlay/session-persistence-rdb Test report

When to use it
Let the agent crunch data — parse, transform, or analyze — so it works with real datasets, not just prose.
Who it's for
Users whose tasks involve tables, files, or numbers that need processing or analysis.
For developers — extending it
Data sources and transformation tools are the seams — add formats, aggregations, or visualization outputs.
