Configuring DSE Tiered Storage
Documentation on configuring DSE Tiered Storage to automate the smart movement of data between storage media.
Configuring the data movement between storage media takes place at the node level and
the schema level:
- Configure the storage strategies to define storage locations, and the tiers
that define the storage locations, at the node level in the
dse.yaml file. Tip: Use OpsCenter Lifecycle Manager to run a Configure job to push the configuration to applicable nodes.
Multiple configurations can be defined for different use cases. Multiple heterogeneous disk configurations are supported.
DataStax recommends local configuration testing before deploying cluster wide.
- Configure the age policy at the schema level.
The only supported data usage policy is partition age. The only supported compaction strategy is DateTieredStorageStrategy. Tier age thresholds are set when a table is created with the compaction strategy TieredCompactionStrategy.
The location of
the dse.yaml file depends
on the type of installation:
Installer-Services | /etc/dse/dse.yaml |
Package installations | /etc/dse/dse.yaml |
Installer-No Services | install_location/resources/dse/conf/dse.yaml |
Tarball installations | install_location/resources/dse/conf/dse.yaml |
