Trino is an open-source distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. [1] Trino can query data lakes that contain a variety of file formats such as simple row-oriented CSV and JSON data files to more performant open column-oriented data file formats like ORC or Parquet [2] [3] residing on different storage systems like ...
DuckDB's SQL parser is derived from the pg_query library developed by Lukas Fittl, which is itself derived from PostgreSQL's SQL parser that has been stripped down as much as possible. [ 12 ] [ 13 ] DuckDB uses a single-file storage format to store data on disk, designed to support efficient scans and bulk updates, appends and deletes.
HBase runs on top of HDFS and is well-suited for fast read and write operations on large datasets with high throughput and low input/output latency. HBase is not a direct replacement for a classic SQL database , however Apache Phoenix project provides a SQL layer for HBase as well as JDBC driver that can be integrated with various analytics and ...
Apache Spark has its architectural foundation in the resilient distributed dataset (RDD), a read-only multiset of data items distributed over a cluster of machines, that is maintained in a fault-tolerant way. [2] The Dataframe API was released as an abstraction on top of the RDD, followed by the Dataset API.
The vague adjectives of very and large allow for a broad and subjective interpretation, but attempts at defining a metric and threshold have been made. Early metrics were the size of the database in a canonical form via database normalization or the time for a full database operation like a backup.
