[ANNOUNCE] Apache CarbonData 1.4.0 release

Liang Chen-2

Apache CarbonData community is pleased to announce the release of the
Version 1.4.0 in The Apache Software Foundation (ASF).

CarbonData is a high-performance big data store solution that supports fast
filter lookups and ad-hoc OLAP analysis. Due to varied business driven
analysis, and the demand for flexibility of data analytics, big data domain
is shadowed with data duplication and increased data management cost.
CarbonData provides a new converged data storage to address data
de-duplication, and supports various application scenarios. CarbonData has
been deployed in 20+ enterprise production environments, largest single
cluster (100+ nodes) managing data of tens of trillions. The I/O scanning
and computing performance is improved by leveraging features such as
multi-level index, dictionary encoding, pre-aggregation, dynamic
partitioning, and quasi-real-time data query; there by achieving
second-level response to analytics query on tens of trillions of data.

We encourage everyone to download the release
https://dist.apache.org/repos/dist/release/carbondata/1.4.0/, and feedback
through mailing list.([hidden email] or
[hidden email])

This release note provides information on the new features, improvements,
and bug fixes of this release.
What’s New in Version 1.4.0?

In this version of CarbonData, following are the new features added for
performance improvements, compatibility, and usability of CarbonData.
Supports SDK

Provided Carbon SDK to write and read CarbonData files through Java API,
supporting Avro schema and JSON data.
Supports External Table with Location

Now you can create external table by specifying the location of Carbon data
Supports Streaming with Pre-Aggregate Table

Now you can create pre-aggregate table on streaming tables. This enhances
OLAP type of query performance on streaming tables.
Supports Partition with Pre-Aggregate

Now when you drop the partition column in the main table, the same column
can be dropped in the aggregate table keeping both in sync.
Enhanced Data Load performance

Now the data load performance has been enhanced
Supports Lucene Index for Text Search (Alpha feature)

This feature allows you to perform text search on Carbon data.
Supports S3 Read on CarbonData FilesSupports Search Mode (Alpha feature)

Supports search mode to improve concurrent queries performance.
Supports Bloom Filter Index (Alpha feature)

This feature fastens blocklet pruning.
