![]() ![]() GRANT ALL ON PROTOCOL s3 TO user1, user2 ![]() For example: CREATE TRUSTED PROTOCOL s3 (writefunc = write_to_s3, readfunc = read_from_s3) If you want to permit non-superusers to use the s3 protocol, create it as a TRUSTED protocol and GRANT access to those users. To allow only Greenplum Database superusers to use the protocol, create it as follows: CREATE PROTOCOL s3 (writefunc = write_to_s3, readfunc = read_from_s3) '$libdir/gps3ext.so', 's3_import' LANGUAGE C STABLE ĭeclare the s3 protocol and specify the read and write functions you created in the previous step: '$libdir/gps3ext.so', 's3_export' LANGUAGE C STABLE ĬREATE OR REPLACE FUNCTION read_from_s3() RETURNS integer AS Perform these steps in each database in which you want to use the protocol:Ĭreate the read and write functions for the s3 protocol library: CREATE OR REPLACE FUNCTION write_to_s3() RETURNS integer AS You must configure the s3 protocol before you can use it. About Specifying the Configuration File Location.About the s3 Protocol Configuration File.About Providing the S3 Authentication Credentials.s3 Protocol AWS Server-Side Encryption Support.About Reading and Writing S3 Data Files.The pxf protocol can also access data in external Hadoop systems (HDFS, Hive, HBase), and SQL databases. The pxf protocol can access data in S3 and other object store systems such as Azure, Google Cloud Storage, and Minio. The s3 protocol also supports Dell EMC Elastic Cloud Storage (ECS), an Amazon S3 compatible service. Greenplum Database uses the S3 URL and prefix specified in the protocol URL either to select one or more files for a read-only table, or to define the location and filename format to use when uploading S3 files for INSERT operations to writable tables. ![]() You can define read-only external tables that use existing data files in the S3 bucket for table data, or writable external tables that store the data from INSERT operations to files in the S3 bucket. For information about Amazon S3, see Amazon S3. The s3 protocol is used in a URL that specifies the location of an Amazon S3 bucket and a prefix to use for reading or writing files in the bucket.Īmazon Simple Storage Service (Amazon S3) provides secure, durable, highly-scalable object storage.
