Multiple Redis Targets
|
|
----------------------
|
|
|
|
You can specify multiple Redis service endpoints by appending a unique identifier ``_ID`` to the end of the top level key for each set of related Redis settings.
|
|
For example, the following commands set two distinct Redis service endpoints as ``PRIMARY`` and ``SECONDARY`` respectively:

.. mc-conf:: notify_redis format
|
|
:delimiter: " "
|
|
|
|
Specify the format of event data written to the Redis service endpoint.
|
|
MinIO supports the following values:
|
|
|
|
``namespace``
|
|
For each bucket event, MinIO creates a JSON document with the bucket and object name from the event as the document ID and the actual event as part of the document body.
|
|
Additional updates to that object modify the existing index entry for that object.
|
|
Similarly, deleting the object also deletes the corresponding index entry.
|
|
|
|
``access``
|
|
For each bucket event, MinIO creates a JSON document with the event details and appends it to the key with a Redis-generated random ID.
|
|
Additional updates to an object result in new index entries, and existing entries remain unmodified.
