| Option | USING_EPHEMERAL_DISKS | |
| Description | Whether to use ephemeral disks on all nodes | |
| Default | false | |
| Valid Values | false | Don't use ephemeral disks |
true | Use ephemeral disks | |
The USING_EPHEMERAL_DISKS option should be set to
true for nodes that have bucket
storage.
When set to true, data is
deleted from Kafka once the data reaches the bucket storage.
Otherwise, if false, the data is
deleted from Kafka once the data is on a sufficient number of
local disk replicas.
While it is not recommended for this variable to be set to
false on a long term basis, it
is convenient to run with
USING_EPHEMERAL_DISKS=false
while migrating to bucket storage. This enables you to validate
that the bucket storage system performs well, but once the
bucket storage has been validated, the variable should be set to
true.
Important
The USING_EPHEMERAL_DISKS option should either
be set on all nodes in a cluster, or on none of them.
USING_EPHEMERAL_DISKS=true
