Column Encoding Utility about amazon-redshift-utils

[IanMeyers]

Hello,

This is currently supported. I've just run the utility for a table with a default option, and as you can see below it does generate the default values:

-- [55069] Connected to xxxxx.eu-west-1.redshift.amazonaws.com:5439:master as master
-- [55069] Analyzing Table 'test_copy_default' for Columnar Encoding Optimisations with 1 Threads...
-- [55069] Analyzing 1 table(s) which contain allocated data blocks
-- [55069] Table test_copy_default contains 5 unoptimised columns
-- [55069] Using Force Override Option
-- [55069] Analyzing Table 'test_copy_default'
-- [55069] Column Encoding will be modified for public.test_copy_default
-- [55069] No encoding modifications required for public.test_copy_default
begin;
lock table public.test_copy_default;
create table public.test_copy_default_$mig(
"column_a" integer  NOT NULL encode raw
,"column_b" integer  NOT NULL encode raw
,"column_c" integer  NOT NULL encode raw
,"id" varchar(10)   encode raw
,"date_value" date default ('now'::character varying)::date  encode raw
)
;
insert into public.test_copy_default_$mig  select * from public.test_copy_default;
analyze public.test_copy_default_$mig;
alter table public.test_copy_default rename to test_copy_default_20161007_2NasFFvFbb_$old;
alter table public.test_copy_default_$mig rename to test_copy_default;
commit;
-- [55069] Performed modification of 0 tables
-- [55069] Processing Complete

Do you see something different when you try to generate a migration script?

Thx,

Ian

I've run it on my entire database with more than 30 tables. Not one table has the default value set. I'm forced to use SQL Workbench to get the SQL source and see what the defaults are and then copy/paste them. Which is a bit time consuming.

My command:

./analyze-schema-compression.py --db adb --db-user auser --db-host xxx.us-east-1.redshift.amazonaws.com --output-file encoding.sql
-- [7281] Column Encoding will be modified for public.app
begin;
lock table public."app";
create table public."app_$mig" (
"id" integer   encode delta 
,"name" varchar(765)   encode lzo 
,"developer" varchar(765)   encode lzo 
,"sku" varchar(765)   encode lzo 
,"appfiguresid" bigint   encode lzo 
,"icon" varchar(765)   encode lzo 
,"currencycode" varchar(765)   encode lzo 
)
;
alter table public."app_$mig" add primary key (id);
insert into public."app_$mig"  select * from public."app";
analyze public."app_$mig";
alter table public."app" rename to "app_$old";
alter table public."app_$mig" rename to "app";
commit;

Maybe I'm running an older version of the code. Let me check.
