#MSDyn365BC Reduce Data Stored in Business Central Tenant - Compress Tables?

Hi all,

In Part 1 and Part 2 we discussed about few ways to Reduce Data Stored in Business Central Database that includes -

  • Delete unused companies
  • Delete documents
  • Use retention policies
  • Migrate BLOB data types to Media or MediaSet

In this article, we will understand a Compress Tables Feature with Business Central.

Business Central supports data compression of tables. Compressing table data saves space and helps improve performance of I/O-intensive workloads.

With Business Central online - 

  • page-level data compression is automatically enabled on tables in a tenant.
  • It's applied to Microsoft extensions and third-party extensions, unless the CompressionType property on a table is explicitly set to None.

There are two ways to enable or change data compression in Business Central:

  • On a table-level, use the CompressionType property on table objects.
  • On a database-level (on-premises only), use the Start-NAVDatabaseCompression cmdlet. This cmdlet is only available with Business Central 2020 release wave 1 and later.

For Table Compression (on-Prem / Online) use - 

For Page Compression (on-Prem) use - 

Start-NAVDatabaseCompression -ServerInstance <Server Name> - Compression Page

Read more about PowerShell cmdlet - Start-NAVDatabaseCompression in MSDN.

Start thinking about Compression when you add new tables in Extensions that you are developing. It will have impact on Database size based on what compression you use.

We will talk about other new features and capabilities in Business Central in future articles.

Stay connected.
