> ABFS: Support for Pagination in Recursive Directory Delete
> -----------------------------------------------------------
>
> Key: HADOOP-18656
> URL: https://issues.apache.org/jira/browse/HADOOP-18656
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.3.5
> Reporter: Sree Bhattacharyya
> Assignee: Anuj Modi
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.5.0
>
>
> Today, when a recursive delete is issued for a large directory in ADLS Gen2
> (HNS) account, the directory deletion happens in O(1) but in backend ACL
> Checks are done recursively for each object inside that directory which in
> case of large directory could lead to request time out. Pagination is
> introduced in the Azure Storage Backend for these ACL checks.
> More information on how pagination works can be found on public documentation
> of [Azure Delete Path
> API|https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/delete?view=rest-storageservices-datalakestoragegen2-2019-12-12].
> This PR contains changes to support this from client side. To trigger
> pagination, client needs to add a new query parameter "paginated" and set it
> to true along with recursive set to true. In return if the directory is
> large, server might return a continuation token back to the caller. If caller
> gets back a continuation token, it has to call the delete API again with
> continuation token along with recursive and pagination set to true. This is
> similar to directory delete of FNS account.
> Pagination is available only in versions "2023-08-03" onwards.
> PR also contains functional tests to verify driver works well with different
> combinations of recursive and pagination features for HNS.
> Full E2E testing of pagination requires large dataset to be created and hence
> not added as part of driver test suite. But extensive E2E testing has been
> performed.
