Re: Load 500 GB test data with Large objects and different types

[Holger Jakobs <holger@xxxxxxxxxx>]

Converting int values to timestamp is possible with PostgreSQL's functions.

The already mentioned generate_series() can generate timestamp values directly.

So you can choose.

What do you mean by large objects? Large binary values can be saved as bytea type or as large objects separate from tables.

Hi Raj.  You can use the generate_series() function to create millions of rows and do an insert from this select.

I'm used to using it in my test data generation.

Hi, 

What is the easy/best way to load 500gb of data for testing purpose with flexible data types

1) Timestamp Datetime

2) Blob Large Objects 

3) Different data types.

I tried pgbench and sysbench which only gives int and varchar types.

Thanks,

Raj Kumar Narendiran.
