v1.4.0 Release Note

Add matrixDB Support
By Ruohang Feng（@Vonng） |

v1.4.0

Architecture

  • Decouple system into 4 major categories: INFRA, NODES, PGSQL, REDIS, which makes pigsty far more clear and more extensible.
  • Single Node Deployment = INFRA + NODES + PGSQL
  • Deploy pgsql clusters = NODES + PGSQL
  • Deploy redis clusters = NODES + REDIS
  • Deploy other databases = NODES + xxx (e.g MONGO, KAFKA, … TBD)

Accessibility

  • CDN for mainland China.
  • Get the latest source with bash -c "$(curl -fsSL http://download.pigsty.cc/get)"
  • Download & Extract packages with new download script.

Monitor Enhancement

  • Split monitoring system into 5 major categories: INFRA, NODES, REDIS, PGSQL, APP
  • Logging enabled by default
    • now loki and promtail are enabled by default. with prebuilt loki-rpm
  • Models & Labels
    • A hidden ds prometheus datasource variable is added for all dashboards, so you can easily switch different datasource simply by select a new one rather than modifying Grafana Datasources & Dashboards
    • An ip label is added for all metrics, and will be used as join key between database metrics & nodes metrics
  • INFRA Monitoring
    • Home dashboard for infra: INFRA Overview
    • Add logging Dashboards : Logs Instance
    • PGLOG Analysis & PGLOG Session now treated as an example Pigsty APP.
  • NODES Monitoring Application
    • If you don’t care database at all, Pigsty now can be used as host monitoring software alone!
    • Consist of 4 core dashboards: Nodes Overview & Nodes Cluster & Nodes Instance & Nodes Alert
    • Introduce new identity variables for nodes: node_cluster and nodename
    • Variable pg_hostname now means set hostname same as postgres instance name to keep backward-compatible
    • Variable nodename_overwrite control whether overwrite node’s hostname with nodename
    • Variable nodename_exchange will write nodename to each other’s /etc/hosts
    • All nodes metrics reference are overhauled, join by ip
    • Nodes monitoring targets are managed alone under /etc/prometheus/targets/nodes
  • PGSQL Monitoring Enhancement
    • Complete new PGSQL Cluster which simplify and focus on important stuff among cluster.
    • New Dashboard PGSQL Databases which is cluster level object monitoring. Such as tables & queries among the entire cluster rather than single instance.
    • PGSQL Alert dashboard now only focus on pgsql alerts.
    • PGSQL Shard are added to PGSQL
  • Redis Monitoring Enhancement
    • Add nodes monitoring for all redis dashboards.

MatrixDB Support

  • MatrixDB (Greenplum 7) can be deployed via pigsty-matrix.yml playbook
  • MatrixDB Monitor Dashboards : PGSQL MatrixDB
  • Example configuration added: pigsty-mxdb.yml

Provisioning Enhancement

Now pigsty work flow works as this:

 infra.yml ---> install pigsty on single meta node
      |          then add more nodes under pigsty's management
      |
 nodes.yml ---> prepare nodes for pigsty (node setup, dcs, node_exporter, promtail)
      |          then choose one playbook to deploy database clusters on those nodes
      |
      ^--> pgsql.yml   install postgres on prepared nodes
      ^--> redis.yml   install redis on prepared nodes

infra-demo.yml = 
           infra.yml -l meta     +
           nodes.yml -l pg-test  +
           pgsql.yml -l pg-test +
           infra-loki.yml + infra-jupyter.yml + infra-pgweb.yml
  • nodes.yml to setup & prepare nodes for pigsty
    • setup node, node_exporter, consul agent on nodes

How to upgrade from v1.1.1

There’s no API change in 1.2.0 You can still use old pigsty.yml configuration files (PG13).

For the infrastructure part. Re-execution of repo will do most of the parts

As for the database. You can still use the existing PG13 instances. In-place upgrade is quite tricky especially when involving extensions such as PostGIS & Timescale. I would highly recommend performing a database migration with logical replication.

The new playbook pgsql-migration.yml will make this a lot easier. It will create a series of scripts which will help you to migrate your cluster with near-zero downtime.

Database

Add additional locale support: lc_ctype and lc_collate.

It’s mainly because of pg_trgm ’s weird behavior on i18n characters.

pg_databases:
  - name: meta                      # name is the only required field for a database

  - name: meta
    schemas: [meta]                 # create extra schema named 'meta'

    parameters:                     # overwrite database meta's default search_path
      search_path: public, monitor

New Schema

pg_databases:
  - name: meta                      # name is the only required field for a database
    owner: postgres                 # optional, database owner
    template: template1             # optional, template1 by default

Changes

  • Add new options: template , encoding, locale, allowconn, tablespace, connlimit
  • Add new option revokeconn, which revoke connect privileges from public for this database
  • Add comment field for database

Apply Changes

You can create new database on running postgres clusters with pgsql-createdb.yml playbook.

  1. Define your new database in config files
  2. Pass new database.name with option pg_database to playbook.
./pgsql-createdb.yml -e pg_database=<your_new_database_name>

User Definition

User provisioning interface enhancement #34

Old Schema

pg_users:

    comment: default test user for production usage
    pgbouncer: true                 # add to pgbouncer

New Schema

pg_users:
  # complete example of user/role definition for production user
  - name: dbuser_meta               # example production user have read-write access
    password: DBUser.Meta           # example user's password, can be encrypted
    login: true                     # can login, true by default (should be false for role)
    superuser: false                # is superuser? false by default
    createdb: false                 # can create database? false by default

    parameters:                     # user's default search path
      search_path: public
    comment: test user

Changes

  • username field rename to name
  • groups field rename to roles
  • options now split into separated configration entries: login, superuser, createdb, createrole, inherit, replication,bypassrls,connlimit
  • expire_at and expire_in options
  • pgbouncer option for user is now false by default

Apply Changes

You can create new users on running postgres clusters with pgsql-createuser.yml playbook.

  1. Define your new users in config files (pg_users)
  2. Pass new user.name with option pg_user to playbook.
./pgsql-createuser.yml -e pg_user=<your_new_user_name>

  • Download newly created offline installation packages: pkg.tgz (v0.5)

Database Provision Template

Now you can customize your database content with pigsty !

pg_users:
  - username: test
    password: test
    comment: default test user
    groups: [ dbrole_readwrite ]    # dborole_admin|dbrole_readwrite|dbrole_readonly
pg_databases:                       # create a business database 'test'
  - name: test
    extensions: [{name: postgis}]   # create extra extension postgis
    parameters:                     # overwrite database meta's default search_path
      search_path: public,monitor

pg-init-template.sql wil be used as default template1 database init script pg-init-business.sql will be used as default business database init script

you can customize default role system, schemas, extensions, privileges with variables now:

# - system roles - #
pg_replication_username: replicator           # system replication user
pg_replication_password: DBUser.Replicator    # system replication password
