Loading Oracle Data to BigQuery

LogMiner Change Data Capture

Suitable for Real-time replication of Oracle to BigQuery. What is it The LogMiner is a chronological view of all SQL transactions on Oracle. How it works
  1. Dump an initial snapshot of the desired tables
  2. Continuously read INSERT, UPDATE & DELETE statements from the LogMiner, then load them into staging tables
  3. Consolidate the staging tables into exact copies of the source tables
  4. Detect schema changes and adjust staging and destination tables
Pros and cons There are several attractive benefits to this method. It’s fast and is able to capture DELETES, INSERTS & UPDATES plus requires less querying overhead. The downside is that it requires retaining archive logs, which consumes more disk space. Pro Tip Allocate enough memory for the LogMiner to work efficiently.

Incremental Replication

Suitable for Real-time replication of Oracle to Bigquery. What is it ODBC connector that continuously queries for changes and replicates them to BigQuery. How it works
  1. Specify a list of tables to replicate
  2. For each table, specify the UPDATE indicator column which can be a Timestamp column indicating a change was committed for a row
  3. Alooma’s integration will continuously query each table for INSERTED or UPDATED records
  4. All changes to all tables will be loaded to corresponding staging tables
  5. Every staging table will be consolidated into an exact replica of the source table
Pros and cons The advantage of this method, is that less setup time is required. However DELETES can’t be migrated.

Oracle to BigQuery - Should you do it yourself or use a third party solution?

DON’T TRY THIS YOURSELF! It’s very complicated. But if you must, use Oracle SQL*Plus to dump tables to CSV files and load them to your data warehouse.
