should you use it?</h2>
-<p>ACID stands for four traits of database transactions: Atomicity (an
operation either succeeds completely or fails, it does not leave partial data),
Consistency (once an application performs an operation the results of that
operation are visible to it in every subsequent operation), <a

(an incomplete operation by one user does not cause unexpected side effects
for other users), and Durabi [...]

<p>Hive User-Defined Functions (UDFs) are custom functions developed in
Java and seamlessly integrated with Apache Hive. UDFs are routines designed to
accept parameters, execute a specific action, and return the resulting value.
The return value can either be a single scalar row or a complete result set,
depending on the UDF&rsquo;s code and the implemented interface. UDFs
represent a powerful capability that enhances classical SQL functionality by
allowing the integration of c [...]
<h2 id="description">Description</h2>
<p>In cloud based deployments, it is common that the user identity is
federated and managed externally by an identity provider (e.g Okta,
PingIndentity, Azure AD). Integrating with such external identity providers
(IDP) would help adoption and unlock use-cases where Hive is deployed in a
cloud based environment and doesn&rsquo;t need user managed authentication
mechanisms (e.g Ldap, Kerberos). There are primarily two authentication
protocols which are standardized with such ext [...]
