I want to read the last modified datetime of the files in data lake in a databricks script. If I could read it efficiently as a column when reading data from data lake, it would be perfect.
Choosing the Right Tools: Select tools optimized for data lake file formats (e.g., Parquet, ORC) and distributed computing frameworks (e.g., Apache Spark, Apache Flink).
Partitioning and Indexing: Partition data logically and create indexes to minimize data scanning.
Optimizing Queries: Write queries that leverage predicate pushdown, column pruning, and other optimizations provided by the data lake engine.
Parallel Processing: Utilize parallel processing to distribute workload across multiple nodes or cores, improving read performance.
Caching and Materialization: Cache frequently accessed data or precompute aggregates to reduce read times for subsequent queries.
