TimescaleDB

Some hyperfunctions are included by default in Timescale. For additionalhyperfunctions, you need to install the TimescaleDB Toolkit PostgreSQLextension.If you're using Timescale, the Toolkit is already installed.On Managed Service for TimescaleDB, run this command on each database youwant to use the Toolkit with:CREATE EXTENSION timescaledb_toolkit;Update an installed version of the Toolkit using this command:ALTER EXTENSION timescaledb_toolkit UPDATE;If you're hosting your own TimescaleDB database, you can install Toolkit by:Using the TimescaleDB high-availability Docker imageUsing a package manager such as yum, apt, or brew on platforms wherepre-built binaries are availableBuilding from sourceInstall Docker imageThe recommended way to install the Toolkit is to use theTimescaleDB Docker image.To get Toolkit, use the high availability image, timescaledb-ha:docker pull timescale/timescaledb-ha:pg17For more information on running TimescaleDB using Docker, see the section onpre-built containers.Install Toolkit on CentOS 7 and other Red Hat-based systemsThese instructions use the yum package manager.

Edition.Install TimescaleDBTo use timescaleDB, make sure that you allowlist the extension, load its library, and install the extension in the database on which you plan to use its functionality.You can now create a TimescaleDB hypertable from scratch or migrate existing time-series data in PostgreSQL.For more information on restoring a Timescale database using pg_dump and pg_restore, see Timescale documentation.Restore a Timescale database using timescaledb-backupWhile running the SELECT timescaledb_post_restore() procedure, you might get permissions denied when updating timescaledb.restoring flag. The reason why you get this error is because of the limited ALTER DATABASE permission in Cloud PaaS database services. In this case, you can perform an alternative method using the timescaledb-backup tool to back up and restore the Timescale database. Timescaledb-backup is a program that makes dumping and restoring a TimescaleDB database simpler, less error-prone, and more performant.To do so, follow these steps:Install tools as detailed here.Create a target Azure Database for PostgreSQL flexible server instance and database.Enable Timescale extension.Grant the azure_pg_admin role to the user that is used by ts-restore.Run ts-restore to restore database.More details on these utilities can be found here.Extensions and major version upgradeAzure Database for PostgreSQL flexible server offers an in-place major version upgrade feature that performs an in-place upgrade of the Azure Database for PostgreSQL flexible server instance, with just a simple interaction from the user. In-place major version upgrade simplifies the Azure Database for PostgreSQL flexible server upgrade process, minimizing the disruption to users and applications accessing the server. In-place major version upgrades don't support specific extensions, and there are some limitations to upgrading certain extensions.The extensions anon, Apache AGE, dblink, orafce, pgaudit, postgres_fdw, and timescaledb are unsupported for all Azure Database for PostgreSQL flexible server versions when using in-place major version update feature.Modules with specific considerationsThe following list enumerates all the supported modules that require specific considerations when used in an Azure Database for PostgreSQL flexible server:pg_failover_slotspg_failover_slotsThe pg_failover_slots extension enhances Azure Database for PostgreSQL flexible server when operating with both logical replication and high availability enabled servers. It effectively addresses the challenge within the standard PostgreSQL engine that doesn't preserve logical replication slots after a failover. Maintaining these slots is critical to prevent replication pauses or data mismatches during primary server role changes, ensuring operational continuity and data integrity.The extension streamlines the failover process by managing the necessary transfer, cleanup, and synchronization of replication slots, thus providing a seamless transition during server role changes.You can find more information and instructions on using the pg_failover_slots extension on its GitHub page.To use the pg_failover_slots extension, make sure that its library was loaded when the server started.Related contentExtensionsAllow extensionsList of extensions and modules by nameList of extensions and modules by version of PostgreSQL --> Feedback Additional resources In

January 9, 2019, 6:15pm 1 I’m working on an IIoT project using Ignition Edge + Ignition central MQTT broker. We are storing data to a postgreSQL database and we are using an abstraction layer called Timescale. Basically this abstraction layer automatically breaks your database into partitions and maintains performance up to 1 Billion rows. (PostegreSQL starts to drop performance after 50 million or so rows in a table) This is nice because you no longer have to use the Ignition Historian partitioning function and all of your timeseries data appears to you as if it’s stored in one table which is really nice for querying from external sources.Check it out: let me know if you would be interested in learning more about our application in a video. pturmel January 9, 2019, 7:02pm 2 I’ve heard very good things about Timescale, though I haven’t needed it (yet). FWIW, I have worked with hundreds of millions of rows in plain PostgreSQL without trouble. BRIN indices on timestamp columns are especially helpful. Thank you Phil! I appreciate that! That is reassuring. dtompkins February 24, 2019, 8:58pm 4 Zack - I stumbled across your post. We are an Ignition shop and are also evaluating Timescale. I was wondering how your project is progressing. Are you still bullish on the Timescale?? zacslade February 25, 2019, 4:21pm 5 Hi Zack! Also curious how you like Timescale. Post again about your experiences Ive been playing with it lately. Installing timescaledb was simple enough because the instructions were good on the Timescaledb website. The install will want to modify the Postgres conf file so make sure you back it up. Timescaledb modifies the conf file in order to optimize the db for insertions. For the most part the db will continue to behave normally but you will notice a bunch of extra tables in the query browser. These tables are for use by Timescaledb to manage the data. The ideal senario is for an Ignition transaction group to log to the Timscale hypertable. The hypertable is an ordinary timeseries table that timescale manages. Its a little tricky to set the transaction group up to use a hypertable but once you do the transaction group logs away as fast as you set it to do so. In a perfect world there would be a button on an historical transaction group that will create the hypertable for you. I thought about this some more. If transaction groups will create the table automatically then a great feature would be for the group to allow the use a preview and ability to edit the table create statement before starting the group. Alternatively the user can create the table first then point the
