[jira] [Resolved] (OAK-10803) Compress in-memory property values

     [ https://issues.apache.org/jira/browse/OAK-10803?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stefan Egli resolved OAK-10803.
-------------------------------
    Fix Version/s: 1.68.0
       Resolution: Fixed

[PR|https://github.com/apache/jackrabbit-oak/pull/1526] merged, thx [~ionutpirlogea]]!

Compression is disabled by default.

We have encountered performance issues that we first need to work through before we can enable it. Created OAK-10973 to look into performance.

> Some properties in the repository can be quite large and consume a considerable amount of memory. E.g. large multi-valued properties, blob IDs that contain an inlined binary.
> With a certain size of the value, it may be beneficial to compress it when loaded into memory/cache and uncompress it only on access. This shouldn't be too difficult and can be implemented in a backward compatible way, because it only affects the in-memory representation and not how data is stored.
