* Update StringUtils.replace() after fix in JDK9 * Upgrade optimized string replace algorithm * Update methods by re-using declared StringUtils#replace method * Replace hard-coded UTF-8 encodings with StandardCharsets
…tionals; cleanup framework init (apache#17829) * cleans up `SqlTestFramework` initialization to leave the `OverrideModule` empty - so that tests could more easily take over parts * remove the `QueryComponentSupplier#createEngine` factory method - instead uses a `Class<SqlEngine>` and use the `injector` to initialize it * enables the usage of `!disabled <supplier> <message>` - to mark cases which are not yet supported with a specific configuration for some reason * fixes that `datasets` was not respecting the `rollup` specification of the ingest * enables to use `MultiComponentSupplier` backed tests - these will turn into matrix tests over multiple componentsuppliers - enabling running the same testcase in different scenarios
Description ----------- apache#17653 introduces a cache for segment metadata on the Overlord. This patch is a follow up to that to make the cache more robust, performant and debug-friendly. Changes --------- - Do not cache unused segments This significantly reduces sync time in cases where the cluster has a lot of unused segments. Unused segments are needed only during segment allocation to ensure that a duplicate ID is not allocated. This is a rare DB query which is supported by sufficient indexes and thus need not be cached at the moment. - Update cache directly when segments are marked as unused to avoid race conditions with DB sync. - Fix NPE when using segment metadata cache with concurrent locks. - Atomically update segment IDs and pending segments in a `HeapMemoryDatasourceSegmentCache` using methods `syncSegmentIds()` and `syncPendingSegments()` rather than updating one by one. This ensures that the locks are held for a shorter period and the update made to the cache is atomic. Main updated classes ---------------------- - `IndexerMetadataStorageCoordinator` - `OverlordDataSourcesResource` - `HeapMemorySegmentMetadataCache` - `HeapMemoryDatasourceSegmentCache` Cleaner cache sync -------------------- In every sync, the following steps are performed for each datasource: - Retrieve ALL used segment IDs from metadata store - Atomically update segment IDs in cache and determine list of segment IDs which need to be refreshed. - Fetch payloads of segments that need to be refreshed - Atomically update fetched payloads into the cache - Fetch ALL pending segments - Atomically update pending segments into the cache - Clean up empty intervals from datasource caches
Prior to this patch, an offset specified on a groupBy that itself has an inner groupBy would lead to an error like "Cannot push down offsets". This happened because of a violated assumption: the processing logic assumes that offsets have been pushed into limits (so limit pushdown optimizations can safely be used). This patch adjusts processing to incorporate offsets into limits during processing of subqueries. Later on, in post-processing, offsets are applied as written.
…ncing (apache#17824) * Do not use segment metadata cache until leader has synced * Read from cache only when synced, but write even if sync is pending * Fix compilation * Fix checkstyle, test * Revert some extra changes * Add 3 modes of cache usage * Move enum to SegmentMetadataCache * Run tests in all 3 cache modes * Fix docs and IT configs * Fix config binding * Remove forbidden api * Fix typos, docs and enum casing * Fix doc
This PR adds the sql-native portion of the json, array, and aggregation function tests to quidem. It adds a total of 9965 queries, with 6752 positive tests and 3213 negative tests.
…I response (apache#17840) Adds support for an optional filename query parameter to the /druid/v2/sql/statements/{queryId}/results API. When provided, the response will include a header Content-Disposition: attachment; filename="{filename}", which will instruct a web browser to save the response as a file rather than displaying it inline. This save-as-attachment behavior could be achieved by adding a "download" attribute to the results link, but this only works for same-origin URLs (as in the Web Console). If the UI origin is different from the Druid API origin, browsers will ignore the attribute and serve the results inline, which is poor UX for files that are potentially very large. For the sake of consistency, all successful responses in SqlStatementResource.doGetResults may include this header, even if there are no results. Release note Improved: The "Get query results" statements API supports an optional filename query parameter. When provided, the response will instruct web browsers to save the results as a file instead of showing them inline (via the Content-Disposition header).

To fix the problem, we should remove the unused segmentMetadataCache parameter from the getTableNames method. This will simplify the method's interface without changing its existing functionality. The changes should be made in the DruidSchemaManager interface in the file sql/src/main/java/org/apache/druid/sql/calcite/schema/DruidSchemaManager.java.

To fix the problem, we need to remove the unused parameter cfg from the validateFrameworkConfig method. This will simplify the method's interface and eliminate the unnecessary parameter. The changes should be made in the file sql/src/test/java/org/apache/druid/quidem/DruidQuidemTestBase.java.
