我如何用Janusgraph禁用（或正确启用）Cassandra表压缩？ 我从Janusgraph连接到kubernetes的Janusgraph的Cassandra群集。卡桑德拉（Cassandra）是5.0.0-jammy版本，Janusgraph是版本1.0.0（在此处图像容器信息） 两个Cassandra节点...

Question

两个Cassandra节点似乎还可以，但是当容器启动时，Janusgraph容器会在下面抛出错误。我找不到对Cassandra，Janusgraph或Gremlin Server文档中此

compression.class属性的任何引用。我看到的最接近的参考是cassandra桌

。 我尝试了表压缩的排列。与Janusgraph.properties相关的Janusgraph设置

，但它们都没有影响：

V1

storage.cql.compression=false
storage.cql.compression-type=

V2

root.storage.cql.compression=false
root.storage.cql.compression-type=

V3

storage.cql.compression=true
storage.cql.compression-type=LZ4Compressor

V4

root.storage.cql.compression=true
root.storage.cql.compression-type=LZ4Compressor

在Janusgraph文档中指出的，Janusgraph 1.0.0不支持Cassandra5.x.
