Orient DB 3.0.18: Compression with name 'snappy' is absent

I am trying to open a database using Orient DB 3.0.18 created using Orient DB v2.2.37, however, the error "Compression with name 'snappy' is absent is outputted". How does one register snappy compression with Orient V3? I tried org.xerial.snappy in the maven POM, but no joy. Thanks in advance.

Solution

  • Resolution for those using Orient DB in embedded mode is as follows:

    1) download OSnappyCompression.java from Orient DB Github repo and incorporate into your project

    2) add the following lib to your Maven pom.xml

     <dependency>
     <groupId>org.xerial.snappy</groupId>
     <artifactId>snappy-java</artifactId>
     <version>1.1.7.3</version>
 </dependency>

    3) register Snappy compression method as follows prior to start of Orient DB

     OCompressionFactory.INSTANCE.register(new OSnappyCompression());
