How to think about read optimized queries?<a class="hash-link" href="#does-hudi-guarantee-consistent-reads-how-to-think-about-read-optimized-queries" title="Direct link to heading"></a></h3><p>Hudi does offer consistent reads. To read the latest snapshot of a MOR table, a user should use snapshot query. The <a href="/cn/docs/table_types#query-types">read-optimized queries</a> (targeted for the MOR table ONLY) are an add on benefit to provides users with a practical tradeoff of decoupling writer performance vs query performance, leveraging the fact that most queries query say the most recent data in the table.</p><p>Hudi’s read-optimized query is targeted for the MOR table only, with guidance around how compaction should be run to achieve predictable results. In the MOR table, the compaction, which runs every few commits (or “deltacommit” to be exact for the MOR table) by default, merges the base (parquet) file and corresponding change log files to a new base file within each file group, so that the snapshot query serving the latest data immediately after compaction reads the base files only. Similarly, the read-optimized query always reads the base files only as of the latest compaction commit, usually a few commits before the latest commit, which is still a valid table state.</p><p>Users must use snapshot queries to read the latest snapshot of a MOR table. Popular engines including Spark, Presto, and Hive already support snapshot queries on MOR table and the snapshot query support in Trino is in progress (the <a href="https://github.com/trinodb/trino/pull/14786" target="_blank" rel="noopener noreferrer">PR</a> is under review). Note that the read-optimized query does not apply to the COW table.</p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="theme-doc-footer-edit-meta-row row"><div class="col"><a href="https://github.com/apache/hudi/tree/asf-site/website/versioned_docs/version-0.14.1/faq_querying_tables.md" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_mS5F" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>Edit this page</a></div><div class="col lastUpdated_mt2f"></div></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Docs pages navigation"><div class="pagination-nav__item"><a class="pagination-nav__link" href="/cn/docs/faq_writing_tables"><div class="pagination-nav__sublabel">Previous</div><div class="pagination-nav__label">Writing Tables</div></a></div><div class="pagination-nav__item pagination-nav__item--next"><a class="pagination-nav__link" href="/cn/docs/faq_table_services"><div class="pagination-nav__sublabel">Next</div><div class="pagination-nav__label">Table Services</div></a></div></nav></div></div><div class="col col--3"><div class="tableOfContents_vrFS thin-scrollbar theme-doc-toc-desktop"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#does-deleted-records-appear-in-hudis-incremental-query-results" class="table-of-contents__link toc-highlight">Does deleted records appear in Hudi's incremental query results?</a></li><li><a href="#how-do-i-pass-hudi-configurations-to-my-beeline-hive-queries" class="table-of-contents__link toc-highlight">How do I pass hudi configurations to my beeline Hive queries?</a></li><li><a href="#does-hudi-guarantee-consistent-reads-how-to-think-about-read-optimized-queries" class="table-of-contents__link toc-highlight">Does Hudi guarantee consistent reads?
