Valentina DB supports several forms of compression that are entirely under the control of the developer.
Valentina DB supports zip compression of Binary Linked Objects (BLOB) from right within the Valentina engine. While you can always zip compress stored objects prior to including them within your database - using Valentina DB built in zip compression has a huge advantage - indexing of TEXT within BLOB objects. Compress BLOB TEXT within Valentina DB and you can automate the indexing of any text within the BLOB object.
Valentina DB zip compression on average reduces size by 7 on BLOB TEXT - meaning a 7 GB text store is reduced to 1 GB on disk.
