@gaoran10 Hi, can you review this?

codelipenghui · 2020-02-22T06:07:58Z

@gaoran10 Please also help review this PR since you have done lots of work in the namespace level offload policy.

Looks good to me, just left some minor comments, please take a look.

    public final static String[] DRIVER_NAMES = {"S3", "aws-s3", "google-cloud-storage", "filesystem"};
    public final static String DEFAULT_OFFLOADER_DIRECTORY = "./offloaders";
+    public final static long DEFAULT_OFFLOAD_OFFLOAD_THRESHOLD = -1;
+    public final static Long DEFAULT_OFFLOAD_OFFLOAD_DELETION_LAG_MS = null;


Maybe the default value of this config could keep the original value (4 hours).

As it's deletion configuration I prefer set the default value to no deletion. WDYT?

I have a question, there are tow CLI-commands can change the managedLedgerOffloadTreshold config and the managedLedgerOffloadDeletionLagMs config, if we use the command set-offload-threshold or set-offload-deletion-lag to set the config first, then we use the command set-offload-policies to set the bucket except for managedLedgerOffloadTreshold and managedLedgerOffloadDeletionLagMs, they will be overridden to default.

"they will be overridden to default.", can you link where override is done?

gaoran10 · 2020-02-22T07:26:59Z

Looks good to me!

Could you fix the description of the command set-offload-policies and get-offload-policies in the doc reference-pulsar-admin.md.

KannarFr · 2020-02-24T14:13:38Z

I am not sure the failing tests are linked to this PR? Isn't it?
