![]() Performance: Delta Lake leverages the columnar storage format of Parquet, providing better compression and encoding techniques, which can lead to improved query performance compared to query CSV files.Reliability: Delta Lake provides ACID transactions, ensuring data consistency and reliability even in the face of failures or concurrent access. ![]() Scalability: Delta Lake is built on top of Open-source Apache license, which is designed to meet industry standards for handling large-scale data processing workloads.Therefore, serverless SQL pool needs less time and fewer storage requests to read the data. Queries that fetch specific column values need not read the entire row data thus improving performance. Parquet file format uses column-wise compression. You can also learn more from the Introduction to Delta Tables video.Īpache Parquet is the baseline format for Delta Lake, enabling you to leverage the efficient compression and encoding schemes that are native to the format. The current version of Delta Lake included with Azure Synapse has language support for Scala, PySpark, and. Azure Synapse Analytics is compatible with Linux Foundation Delta Lake. Delta Lake provides ACID (atomicity, consistency, isolation, and durability) transactions, scalable metadata handling, and unifies streaming and batch data processing on top of existing data lakes. It's important to take these additional costs into consideration when deciding to use this feature as they are not optional and must be paid in order to continue using this feature.ĭelta Lake is an open-source project that enables building a lakehouse architecture on top of data lakes.More information: Azure Synapse Analytics pricing The cost of conducting Spark computing mainly depends on the time interval for incremental update and the data volumes. These costs are related to the usage of Azure Synapse workspace Spark and are billed monthly. Charges are only incurred once a Spark job is executed on the target Spark pool and the Spark instance is instantiated on demand. There are no costs incurred with the creation of Spark pools.But the delta lake table will have an in-place update structure because the delta lake conversion comes with a periodic merge process. ![]()
