To load two specific days of data, you must run the COPY command twice with a filespec for each day. On the Security Groups tab, click the blue Create Cluster Security Group button. Execute the ANALYZE COMPRESSION command on the table which was just loaded. Any name you like that refers to this group. Note: Cluster Security Groups are only necessary in EC2 Classic accounts when you are running outside of a VPC. Use the CREATE TABLE command below to create the table: CREATE TABLE elb_logs ( RequestTime DateTime encode lzo, ELBName varchar(100) encode lzo, RequestIP_Port varchar(22) encode lzo, BackendIP_Port varchar(22) encode lzo, RequestProcessingTime FLOAT encode bytedict, BackendProcessingTime FLOAT encode bytedict, ClientResponseTime FLOAT encode bytedict, ELBResponseCode varchar(3) encode lzo, BackendResponseCode varchar(3) encode lzo, ReceivedBytes BIGINT encode lzo, SentBytes BIGINT encode lzo, HttpRequest varchar(5083) encode lzo, UserAgent varchar(500) encode lzo, SSL_Cipher varchar(40) encode lzo, SSL_Protocol varchar(40) encode lzo ). Even if the COPY command determines that a better encoding style exists, it’s impossible to modify the table’s encoding without a deep copy operation. Choosing the right encoding algorithm from scratch is likely to be difficult for the average DBA, thus Redshift provides the ANALYZE COMPRESSION [table name] command to run against an already populated table: its output suggests the best encoding algorithm, column by column. When your cluster is ready, “available” appears in the Cluster Status column: To see all the details for your cluster, click the Info icon next to the cluster name to display the screen below. -- Create a temp table to load new customer data, -- Load new customer data into the staging table, 'aws_access_key_id=xxxxxxx;aws_secret_access_key=xxxxxxx', -- Update customer email and name for existing rows, -- End transaction. ... , event_Actor1_Geo_Full_Name varchar(500) encode lzo, event_Actor1_Geo_Country_Code varchar(100) , event_Actor1_Geo_ADM1_Code varchar(100) , event_Actor1_Geo_Lat float , event_Actor1_Geo_Long float , event_Actor1_Geo_FeatureID varchar(100) , event_Actor2_Geo_Type int , … This determines whether the cluster can be accessed over the Internet as opposed to through a VPN or through a bastion host. If you plan to run the SQL client on an Amazon EC2 instance, know the security group protecting that instance. SqlBulkCopy Tutorial. UPSERT is a method of deduplicating data when copying into Amazon Redshift or other databases. Redshift Analyze command is used to collect the statistics on the tables that query planner uses to create optimal query execution plan using Redshift Explain command.. Analyze command obtain sample records from the tables, calculate and store the statistics in STL_ANALYZE table. Instead, Redshift recommends the use of a staging table for merging records by joining the staging table with the target table. With a few quick steps, you set up and populated a data warehouse containing a huge log of access requests and ran queries against that warehouse to gain insight into your ELB traffic. After analyzing your data, remember to delete your cluster so you’re not charged for it. redshift - analyze compression atomic.events; Gabriel Awesome: Jul 2, 2015 12:52 PM: Posted in group: Snowplow: I'm just training myself up on redshift a little more and tried this command: analyze compression atomic.events; I only have about 250,000 rows of production data, and some but not all columns in use. This Utility Analyzes and Vacuums table(s) in a Redshift Database schema, based on certain parameters like unsorted, stats off and size of the table and system alerts from stl_explain & stl_alert_event_log. An “upsert” operation merges new records with existing records using primary keys. Once it is complete, there are a couple additional steps to run that format your data for the best possible query performance. def self.
