Product Technical Overview Paper: Zen Data Management

Actian announced their latest flagship product, Actian Zen v15, on July 14, 2021! Previously known under other names such as Actian PSQL, Pervasive PSQL, Pervasive.SQL, and Btrieve, this release is adds quite a few new features that dig deep into the core of the engine to provide new functionality and features for both developers and end users.

What's New In Zen v15?

Here is a list of the most important new features in this release:

  • Performance Improvements: Actian's SQL development team has made the engine faster oiverall through a series of changes:
    • File Close Delay: By delaying (slightly) a File Close operation, a subsequent FileOpen request for the same file can be completed with less work, thus reducing latency when re-opening a file. This value defaults to 50ms and can be changed to 0 to disable this feature, if you see problems.
    • Transaction Log Changes: The transaction log file size and buffer size have been increased to reduce disk write loads.
    • SQL DELETE Operations: A DELETE statement from SQL can now leverage the DeleteExtended function, improving the performance of multi-row delete operations.
    • SQL LIKE Optimizations: As with the DELETE operation, the LIKE clause in SQL now supports push-down filters to the MKDE, offering additional performance gains.
    • Scalar Subqueries: A new optimization on non-correlated, scalar subqueries (i.e. those that return a single value not based on the primary table) may improve SQL queries considerably.
    Even better, many of these optimizations require no changes on the part of the user or programmer!
  • System Data v2: The v13 file format has been extended to support a second System Data option. The System Data v2 block contains a true septasecond TIMESTAMP from when the record was inserted, along with a second septasecond TIMESTAMP field indicated the most recent UPDATE time. This new feature enables tracking of database updates within the MKDE, which may be helpful for writing synchronization and replication solutions. Even better, both internal fields are accessible from SQL as the special column names sys$create and sys$update. This is something which we have been asking for for some time!
  • File Size Limit for Backward Compatibility: If you need to use the newer file format to access the new system data values, this can have an ancillary effect when you are dealing with very large data sets. If you accidentally exceeding the old 256GB file size limit (or 4B records in a file), some functions will fail or return bad data unless you are using the newer BTRVEX function call. This new switch enables you to use the new features of the new file formats (such as the enhanced system data) while still using the older BTRV/BTRCALL interface.
  • SQL Windowing Functions: Another developer change, new SQL features designed to deal with time series data are added, such as the OVER(PARTITION...) syntax, which implement a subset of the ANSI SQL windowing functions, such as rolling averages.
  • Administrative Changes: The BUTIL -STAT, BMON, ande BCFG tools now accept a -JSON option to return data that can be more easily handled by scripting applications (like PowerShell). Additionally, Windows engines will now submit log messages to the Windows Event Log, in addition to the ZEN.LOG.
  • API Updates: Several applicaton programming interfaces have been updated for developers:
    • Btrieve 2 Improvements: Developers using the Btrieve 2 interface can now leverage the BulkDelete operation, as well as access the System Data v2 information block.
    • PDAC/BPL Changes: The PDAC libraries (BPL files) are no longer installed by default, but are still part of PDAC SDK download.
    • ADO.NET Changes: The ADO.NET Data Provider 4.3 has been removed, v4.4 is unchanged, and a new 4.5 release has been added for .NET Core 2.1.
    • Two APIs Removed: The ActiveX and OLEDB SDK's have been discontinued as of this release. Programs developed with previous versions of these SDKs will continue to work properly on Zen v15. If you are a developer using these interfaces, you should start transitioning to ADO.NET or ODBC instead.
  • Platform Changes: As Microsoft has already ended support for Windows 7 and Windows Server 2008 R2, these products will not be tested nor formally supported by Actian in this release. This does not mean that they won't work, but just that these combinations will not be tested. New to v15 is Windows 10 IoT Enterprise, and we expect Windows 11 to be officially supported with the release of Service Pack 1 some time this winter.

Check out the official What's New document for additional information.

Supported Operating Systems and Hardware Requirements

Officially supported operating systems include Windows 10 and Windows Server 2012 (and newer), along with various OS X and Linux distributions and versions. Windows 7, Windows Vista, Windows XP, Server 2003, Server 2008 R2 (and older) operating systems are not formally supported by Actian with this release. We are still awaiting specific information on Windows 11 support, but we expect this to be available with the first Service Pack.

There are no stated minimum hardware requirements. Essentially, if you can run the OS, you can run the database engine. However, performance will be commensurate with the resources provided, as well as the workload.

Actian Zen v15 License Models

Actian Zen v15 has five different license models to choose from:

  • Workgroup Engine: Per-user licensing, up to a maximum of 5 concurrent users
  • Enterprise Server Engine: Per-user licensing, starting at 6 concurrent users
  • Cloud Server Engine: Data size licensing (with unlimited users), ideal for web/SaaS installations
  • Edge Engine: Small edge devices with support for ARM (Raspbian) or x86 (Windows IoT Servers)
  • Core Library: An ultra-small (and free) database library for your Android or iOS applications

Please see our Zen v15 License Primer for more information on the various license types and other factors that might help you determine the best license type for your environment.

If you have decided on per-user licensing, but you are still not sure if you want the Workgroup Engine or one of the server engines, check out our Workgroup Versus Server Comparison Chart.

Pricing for each of these license models can be found on our Actian Zen v15 price list, or you can BUY IT SOON from our on-line store. If you want to try out different license models before you buy (a really good idea!), you can get trial downloads from here.

Still not sure which license model or size to get?
