![]() Used to map the roles defined in the Data Virtuality Server to the roles on the Snowflake side. If the property is not set it is used to cache the default role gotten from Snowflake via the "select current_role()" command during the creation of connection to Snowflake (in most cases it will be the SYSADMIN role)Įnables/disables the Snowflake roles usage For blob_azure uploadMode onlyĭefines the role that is used to retrieve Snowflake metadata. SAS Token used for accessing the Blob Storage from Snowflake. If the user uses the Chinese language for the column, he should specify a value of 300 for the property, meaning it is necessary to add 300 percent to the original field length (32 + 300 % = 128).Īlso, there is a special value: 65535 which makes every varchar to be of 65535 bytes long If the user knows that the data contain English chars only, he may not specify it at all, and the resulting column in the target will be varchar(32) (bytes this time). You can specify the percentage by which the byte size will exceed the original char size.įor instance, if in an original DBMS there is a varchar(32) column (32 chars), the actual data of 32 chars long may occupy 32 bytes for the English alphabet or 128 bytes for Chinese characters. You can read and set the values for keyId and secretKey via the AWS console -> S3 -> username in the upper right corner -> Security Credentials -> Access Keys (Access Key ID and Secret Access Key)Īs Redshift and Vertica measure varchar size in bytes, not chars, and store strings in UTF-8 encoding, a char may be 1 to 4 bytes long. Specifies if the bucket set by the bucketName property should be created if it does not exist The bucket will be deleted after the operation is finished The name of the bucket created for uploading will start with the specified prefix. Specifies a prefix of a bucket name to upload data files to. If no bucketName is specified, a bucket will be created and deleted after the operation is finished The region specified for the bucket must be the same as the region specified via the region translator property. If specified, the specified bucket is used and assumed to exist (no creation/deletion operations performed). Specifies a bucket name to upload data files to. Specifies the folder to be used for creating temporary files instead of the system configured one Value: a path to a folder (relative or absolute). ![]() Translator properties storageAccountName, storageAccountKey, and sasToken should be specified for the mode to work properly Uploads data as files on Azure Blob storage. The value is case-insensitive, so s3Load and S3LOAD are the same values Translator properties region, keyId, and secretKey should be specified for the mode to work correctly. Uploads data as files on Amazon S3 storage. If FALSE, only LOB values will trigger the use of PreparedStatementsĮmbeds a / comment / leading comment with session/request id in the source SQL query for informational purposes ![]() If TRUE, indicates that PreparedStatements should be used and that literal values in the source query should be replaced with bind variables. Please note that the Data Virtuality Server only has string or varchar type that treats trailing whitespace as meaningful If TRUE, trims trailing whitespace from fixed-length character strings. If TRUE, indicates that the source supports strings in the ORDER BY clause If FALSE, the Data Virtuality Server does not push down the ORDER BY clause if it contains at least one expression of string type. if OrderByStringConversion is set, default for supportsOrderByAlias is FALSE.if OrderByStringConversion is not set, same as supportsOrderBy.If TRUE, indicates that the source supports aliases in the ORDER BY clause If FALSE, the Data Virtuality Server does not generate aliases in the ORDER BY clause. MySQL, PostgreSQL, Redshift, Snowflake, Oracle, MS SQL Server Exasol, Vertica, Bigquery, SingleStore, Azure:., ARRAYTABLE( w.tuple COLUMNS query string, pid integer, elapsed string, "substring" string ) x If TRUE, all identifiers in the final query (that is being generated by a translator to be sent directly to the target DBMS) will be quotedĬALL "dwh.native"("request" => 'SELECT query, pid, elapsed, substring FROM svl_qlog ORDER BY STARTTIME DESC LIMIT 200') Tables with non-matching names will only be accessible until the server restarts When set to FALSE, allows creation of tables with names that do not match the tableNamePattern. Only considered when importer.tableNamePattern is set.
