Subject [DISCUSSION/ANNOUNCEMENT] availability of ColumnManager for HBase - beta-02 - via GitHub & Maven
Date Fri, 22 Jul 2016 01:56:52 GMT
The beta-02 release of ColumnManager for HBase is now available on GitHub
and via the Maven Central Repository.

>From the top of the README:
ColumnManagerAPI for HBaseâ„¢ is an extended METADATA REPOSITORY SYSTEM for
HBase with options for:

COLUMN AUDITING -- captures Column metadata (qualifier and max-length*) as
Tables are updated (or via a discovery facility for previously-existing
administratively-managed Column definitions (stipulating valid name,
length, and/or value) as Tables are updated, optionally bringing HBase's
"on-the-fly" column-qualifier creation under centralized control.
SCHEMA CHANGE MONITORING -- tracks and provides an audit trail for
structural modifications made to Namespaces, Tables, and Column Families.
SCHEMA EXPORT/IMPORT -- provides schema (metadata) export and import
facilities for HBase Namespace, Table, and all table-component structures.
A basic COMMAND-LINE INTERFACE is also provided for direct invocation of a
number of the above-listed functions without any need for Java coding.

* coming soon in beta-03: discovery of number-of-occurrences for each
unique column-qualifier in a table.

We've already had some useful discussions about ColumnManager over on the
HBase Slack channel, but it would be great to get broader
feedback/commentary on this from the hbase-user collective. And it would be
especially useful if you can set up an HBase sandbox and try out the
ColumnManager functionality! If you do, please post basic feedback via
reply to this msg, or send a note to support@commonvox.org, or open an
issue on the GitHub project page if you run into problems.

Here are some of the most pertinent links:

Thanks a bunch for taking a look!
