User Guides

Labels allow users to have read-only query access to a snapshot of the database at an earlier point in time. Snapshots are accessible regardless of concurrent activities on other connections, like ETL, preparing new data.


Administrator Guides

LucidDB is designed to require as little administration as possible, so we hope this section can remain short :)

  • Memory Management
    • Buffer Pool Sizing
      You should also increase the buffer pool sizing to increase the amount of memory that LucidDB uses to "run queries"
      (the Java adjustments will only increase the catalog/parsing/optimizer memory settings but not the actual execution engine).
  • System Procedures
Useful for: Backup/Restore, Generating DDL for tables and other objects, managing sessions.
Useful information about tweaking: Memory usage, network settings, execution, and storage functionality.
The DBA views defined by LucidDB provide a global picture of the contents of the system catalog (tables, columns, etc) and the volatile state of the system (sessions, cache utilization, etc).

Function and SQL Language Reference Guides


Connectors to External Data Sources (SQL/MED) (Management of External Data)

See more general information about connectors here [http://www.dynamobi.com].
See more general information about connectors here [http://www.dynamobi.com].

These connectors wrap up external datasources and allow them to present their data as foreign tables inside of LucidDB. Connectors are an adapters that generally allow normal SQL queries to be run against datasources that may not support the SQL language directly.

Presentations / Blogs

Demonstrates loading data, defining an OLAP cube, and browsing the cube with Pentaho, Jaspersoft, SpagoBI and Saiku which all use Mondrian to drive their OLAP functionality.
Webex Presentation and PDF of slides presenting benefits and features of LucidDB 0.9.3 in conjunction with Pentaho's BI Suite.
DynamoBI (Commercial Sponsor of LucidDB) - CEO Nick Goodman - shares vision about how LucidDB forms an information hub from which many different data sources can be presented and queried through normal SQL.


Tutorial Videos and Screencasts

This is an approach that may also work well on Windows. There is another approach, which is shorter and easier using the BASH shell under Linux. Documentation for both approaches can be found at LucidDbAsDaemonService.
  • Moving tables from one database to LucidDB
Using Pentaho Data Integration to generate SQL for moving tables from an external database to LucidDB
This link is actually to a document about upgrading version to version of LucidDB, but because a PDI transformation file is used to generate SQL for the transition, the process can be generalized as moving from an external database to LucidDB with only minor modifications to the transformation.

Experimental

LucidDB does not currently support DDL for automatic horizontal partitioning of tables. Although LucidDB's column-store architecture implements automatic vertical partitioning, horizontal partitioning is still a useful technique for scaling up to very large data volumes, so this page describes some manual approaches which can be used for very simple schemas.
The main client API for LucidDB is JDBC. This page discusses some options for overcoming the obstacle of developing an application in a language other than Java.
Description of how to make use of some of the diff-based testing frameworks built into LucidDB for the purpose of test-driven ETL script development.
