-----------------------------------
Summary: Allow the creation of a cluster-configuration disk-store
record without creating store directories and files
Key: GEODE-7123
URL: https://issues.apache.org/jira/browse/GEODE-7123
Project: Geode
Issue Type: Improvement
Components: management
Reporter: Kenneth Howe
This enhancement provides support for configuring PDX persistence using
non-DEFAULT disk-store.
The recommendation is to use a user-specified disk-store for PDX persistence as
per this excerpt from the Geode docs:
{code:
title=https://geode.apache.org/docs/guide/19/developing/data_serialization/persist_pdx_metadata_to_disk.html}
If you are using PDX serialized objects as region entry keys and you are using
persistent regions, then you must configure your PDX disk store to be a
different one than the disk store used by the persistent regions.
{code}
PDX persistence can be configured using {{gfsh}}:
{code}
configure pdx --read-serialized=true --disk-store=<disk-store-name>
{code}
The previous should only be run on an otherwise non-configured cluster so that
the PDX configuration will be adopted be servers as they join the cluster.
However, to use a non default diskstore, the cluster currently must have at
least one server member and the disk-store must already be created.
*Proposed Enhancement*
Add an option to the {{gfsh}} {{create disk-store}} command to only add the
cluster-configuration record for the disk-store. Server members will then
create the disk-store when they join.
{code}
gfsh>help create disk-store
NAME
create disk-store
. . .
stage-configuration
Only create the cluster configuration element for the disk-store. The
disk-store will be created on any future servers to join the cluster.
Required: false
Default (if the parameter is specified without value): true
Default (if the parameter is not specified): false
gfsh>create disk-store --name=PDXSTORE --dir=pdxstore --stage-configuration
{code}
I will push a proof-of-concept branch to my geode fork
