Re: [VOTE] Accept Lens into the Apache Incubator (earlier called Grill)
It looks like the version [1] of the Wiki page that was active at the time of the vote was: https://wiki.apache.org/incubator/LensProposal?rev=4 [1] https://wiki.apache.org/incubator/LensProposal?action=info For the record, the current contents of that version are appended below: -- cut here Lens Abstract Lens is a platform that enables multi-dimensional queries in a unified way over datasets stored in multiple warehouses. Lens integrates Apache Hive with other data warehouses by tiering them together to form logical data cubes. Proposal Lens provides a unified Cube abstraction for data stored in different stores. Lens tiers multiple data warehouses for unified representation and efficient access. It provides SQL-like Cube query language to query and describe data sets organized in data cubes. It enables users to run queries against Facts and Dimensions that can span multiple physical tables stored in different stores. The primary use cases that Lens aims to solve: Facilitate analytical queries by providing the OLAP like Cube abstraction Data Discovery by providing single metadata layer for data stored in different stores Unified access to data by integrating Hive with other traditional data warehouses Background Apache Hive is a data warehouse that facilitates querying and managing large datasets stored in distributed storage systems like HDFS. It provides SQL like language called HiveQL aka HQL. Apache Hive is a widely used platform in various organizations for doing adhoc analytical queries. In a typical Data warehouse scenario, the data is multi-dimensional and organized into Facts and Dimensions to form Data Cubes. Lens provides this logical layer to enable querying and manage data as Cubes. The Lens project is actively being developed at InMobi to provide the higher level of analytical abstraction to query data stored in different storages including Hive and beyond seamlessly. Rationale The Lens project aims to ease the analytical querying capabilities and cut the data-silos by providing a single view of data across multiple data stores. Conceiving data as a cube with hierarchical dimensions leads to conceptually straightforward operations to facilitate analysis. Integrating Apache Hive with other traditional warehouses provides the opportunity to optimize on the query execution cost by tiering the data across multiple warehouses. Lens provides Access to data Cubes via Cube Query language similar to HiveQL. Driver based architecture to allow for plugging systems like Hive and other warehouses such as columnar data RDBMS. Cost based engine selection that provides optimal use of resources by selecting the best execution engine for a given query. In a typical Data warehouse, data is organized in Cubes with multiple dimensions and measures. This facilitates the analysis by conceiving the data in terms of Facts and Dimensions instead of physical tables. Lens aims to provide this logical Cube abstraction on Data warehouses like Hive and other traditional warehouses. Initial Goals Donate the Lens source code and documentation to Apache Software Foundation Build a user and developer community Support Hive and other Columnar data warehouses Support full query life cycle management Add authentication for querying cubes Provide detailed query statistics Long Term Goals Here are some longer-term capabilities that would be added to Lens Add authorization for managing and querying Cubes Provide REST and CLI for full Admin controls Capability to schedule queries Query caching Integrate with Apache Spark. Creating Spark RDD from Lens query Integrate with Apache Optiq Current Status The project is actively developed at InMobi. The first version is deployed at InMobi 4 months back. This version allows querying dimension and fact data stored in Hive over CLI. The source code and documentation is hosted at GitHub. Meritocracy We intend to build a diverse developer and user community for the project following the Apache meritocracy model. We want to encourage contributors from multiple organizations, provide plenty of support to new developers and welcome them to be committers. Community Currently the project is being developed at InMobi. We hope to extend our contributor and user base significantly in the future and build a solid open source community around Lens. Core Developers Lens is currently being developed by Amareshwari Sriramadasu, Sharad Agarwal and Jaideep Dhok from InMobi, and Sreekanth Ramakrishnan who is currently employed by SoftwareAG. Raghavendra Singh from InMobi has built the QA automation for Lens. Alignment The ASF is a natural home to Lens as it is for Apache Hadoop, Apache Hive, Apache Spark and other emerging projects in Big Data space. We believe in any enterprise, multiple data warehouses will co-exist, as not all workloads are cost effective to run on single one. Apache Hive is one of the crucial data warehouse along with upcoming
