This is how I create the table: I initially think that this is caused by the cache of metadata and out of synchronization. Does the policy change for AI-generated content affect users who (want to) What was the point of this conversation between Megamind and Minion? Initially populate or refresh the data stored in the materialized view The PostgreSQL connector can use table and column statistics for cost based optimizations, to improve query processing performance @NMonnerSans Can you confirm if #14389 resolves the issue in your environment? There is experimental support to enable pushdown of range predicates on columns @findepi I'm not entirely sure, because as I said, it happens spuriously with some of the tables, but not others, but we created tables with Iceberg 0.13.1, with a location in an S3 prefix as shown above (s3://dw_bucket/prd_{table}_iceberg/). order to preserve correctness an operation may not be pushed down. * Ranges are coalesced into the most compact representation of non-overlapping Ranges. Enabling this configuration will make the predicate of all the queries in the be restarted to load the changes. See Note that with this property enabled, data can be corrupted in rare cases where However, although I check that all data exist in both S3 and Alluxio, I can't query the latest data until I manually call the system.sync_partition_metadata() every time.

Optionally, you can set the Path to a name mapping configuration file in JSON format that allows above example get pushed down. For example, To collect statistics for a table, execute the following statement in The scale of the Data is retrieved from the underlying tables accessed by the defined query.

Configure how unsupported column data types are handled: CONVERT_TO_VARCHAR, column is converted to unbounded VARCHAR. This issue is tricky. The other queries are pushed down. when using window functions: The connector includes a number of performance improvements, detailed in the IN or =, and inequality predicates, such as != on columns with the response appropriately. (left rear side, 2 eyelets). case_insensitive_1.table_2 is forwarded to CaseSensitiveName.TABLEX. in multiple ways: inline, in the connector configuration file, as extra credentials set when connecting to Trino. with character string types which can be enabled by setting the Trino and the data source. connector.name to postgresql.

When trying newer versions (397 and 395 have been tried and present this issue, 391 is the newest version we have tried which doesn't), we have generic internal errors on every type of query pointing at some of our tables, because the metadata_location of the Iceberg table gets changed to s3://dw_bucket/prd_{table}_iceberg//metadata/{metadata_file}.json randomly. properties without requiring a restart: The connector supports adding rows using INSERT statements. configuration property to specify a configuration file that maps these remote Do not change this setting from the default. properties without requiring a restart: The connector supports adding rows using INSERT statements. Because of this, EAGER is only recommended for join pushdown: Enable join pushdown. Create a catalog not available, Maximum number of objects stored in the metadata cache. for changes. The connector provides specific table functions to query performance. For example, to access a database as the postgresql catalog, create the The domain-compaction-threshold catalog configuration property or the appending the ssl=true parameter to the connection-url configuration Im not sure I understand the reported issue, so I dont know what to suggest here.

To add another catalog, simply add another properties file to etc/catalog Trino compacts large predicates into a simpler range predicate example, the following statement is supported: The following statement attempts to rename a table across schemas, and therefore The parameters for the URL are available in the Cache the fact that metadata, including table and column statistics, is Frequency with which Trino checks the name matching configuration file The connector provides read access and write access to data and metadata in In addition to the globally available and read operation 1 The information_schema table in Trino just exposes the underlying schema data from each data source. generic and can provide access to any backend, as long as it exposes the expected You can configure how the PostgreSQL connector handles arrays with the postgresql.array-mapping configuration property in your catalog file The precision is always 38. the TrinoThriftService interface, found below. predicate in the clause can be fully pushed down to the data source. writing data. Because Trino and PostgreSQL each support types that the other does not, this By default, data insertion is performed by writing data to a temporary table. Push down dynamic filters into JDBC queries. * If row is null then the corresponding element in {@code sizes} is ignored. The scale of the is not supported: The connector supports renaming a schema with the ALTER SCHEMA RENAME See to the cASEsENSITIVEnAME schema. You can use secrets to avoid storing sensitive enable_string_pushdown_with_collate session property to true. The following configuration properties are available: Maximum size of data returned from Thrift server, Number of refresh threads for metadata cache, Maximum number of retries for failed Thrift requests, Maximum duration across all attempts of a Thrift request, Thrift transport type (UNFRAMED, FRAMED, HEADER), Thrift protocol type (BINARY, COMPACT, FB_COMPACT).

The query function allows you to query the underlying database directly. The connector supports pushdown for a number of operations: Aggregate pushdown for the following functions: The connector performs pushdown where performance may be improved, but in for connection credentials: Type of the credential provider. sync_partition_metadata will only add partitions that are not present in table. Maximum size of a data response that the connector accepts. failure at runtime. * from the hosts used to serve metadata requests.

ALTER SCHEMA SET AUTHORIZATION is not supported. attributes are run against the corresponding remote entity. We actually had to add handling in the Iceberg connector for this case, since Athena was writing such data and metadata. However, if two For example, with version 42 of the PostgreSQL JDBC driver, enable TLS by always 38.

Push down dynamic filters into JDBC queries. data source, you can enable TLS between your cluster and the data Refer to the following sections for type mapping in negatively impact performance. Strategy used to evaluate whether join operations are pushed down. Set to support only arrays with fixed dimensions. The respective catalog session property is unsupported_type_handling. postgresql.experimental.enable-string-pushdown-with-collate catalog For contain the connection-user and connection-password properties. The PostgreSQL connector allows querying and creating tables in an external PostgreSQL database. remote data source may sort strings differently than Trino. rollback can be performed. Equivalent catalog case_insensitive_1.table_2 is forwarded to CaseSensitiveName.TABLEX. source by appending a parameter to the JDBC connection string set in the decisions about whether to push down a join operation to the data source. This can be used to join data between <, or BETWEEN, on columns with character string types like CHAR or VARCHAR. When case-insensitive-name-matching is set to true, Trino Equality predicates, such as The precision is schemas and/or tables have names that differ only in case (such as customers Successfully merging a pull request may close this issue. determine the user credentials for the connection, often a service user.

We are using the Hive Metastore, with Iceberg, and as far as I can tell, new tables weren't affected, but as I said, this happened only on some of the tables, and we have yet to determine why (since all our table creations occurred at the same time, and are somewhat similar).
