# Subsequent syncs - incremental updates (much faster!)
./LakeXpress syncSource - Oracle Database
Oracle Database is the world's most widely used enterprise database. LakeXpress uses FastBCP with optimized Oracle connectors for high-performance data extraction to Parquet format.
Features:
- •Native Oracle ODP.NET driver via FastBCP
- •Full support for Oracle-specific types
- •Parallel extraction to Parquet files
- •Optimized for large volumes
Format - Apache Parquet
Parquet is the industry-standard columnar file format for analytics. LakeXpress uses FastBCP to extract data from source databases and convert it to Parquet format, ensuring optimal compression, query performance, and compatibility with all modern data platforms.
Advantages:
- •Columnar format optimized for analytics
- •Efficient compression (typically 3-10x)
- •Schema evolution support
- •Predicate pushdown for fast queries
- •Universal compatibility with cloud platforms
- •Preserves data types and precision
Cloud Stage - Azure Blob Storage
Azure Blob Storage is Microsoft's object storage solution for the cloud. LakeXpress uses Azure Blob as an intermediate staging layer for Parquet files with high performance and reliability.
Features:
- •Massive scalability
- •Multiple access tiers (Hot, Cool, Archive)
- •Integrated with Azure ecosystem
- •Built-in encryption and security
- •Lifecycle management policies
Destination - Databricks
Databricks provides a unified analytics platform built on Apache Spark. LakeXpress publishes Parquet files as Delta Lake tables for optimal lakehouse performance.
Publishing method:
Delta Lake MERGE or COPY INTO
Features:
- •Native Parquet and Delta Lake support
- •ACID transactions
- •Time travel and versioning
- •Optimized for analytical queries
- •Unity Catalog integration
