Checking and Improving Column Compression and Encoding

Bryan Herger, Vertica Big Data Solution Architect at Micro Focus
November 7, 2019

When working with terabytes of data, storage and transfer become major time and cost sinks. Vertica can help minimize storage cost and transfer time with column compression and encoding. How can we identify Vertica tables that might benefit from compression? Information about column size and current compression is stored across column_storage and projection_columns table. The...

Waqas Dhillon, Product Manager - Machine Learning, Vertica
October 28, 2019

Co-authored by James Clampffer, Deepak Majeti. A lot of projects require querying ORC or Parquet files, or other data that may have internal types that are a bit more complex than usual.

Get the Row Count from an Outer Table Join

Jim Knicely, Vertica Principal Solution Architect
October 22, 2019

Aggregate functions summarize data over groups of rows from a query result set. When using an aggregate function like COUNT with an "*" or "1" parameter value, you may get a different result when the query implements a LEFT join verses an INNER join. If you want a row count of just the rows from...

DIRECT Is Now the Default Load Type

Jim Knicely, Vertica Principal Solution Architect
October 19, 2019

Write Optimized Store (WOS) is a memory-resident data structure for short-term data storage while Read Optimized Store (ROS) is a highly optimized, read-oriented, disk storage structure, organized by projection. Prior to Vertica 9.3, by default, Vertica initially loads data into WOS. For databases created in version 9.3 and later, Vertica now uses a default load...

Vertica 9.3 Supports UPDATE and DELETE Operations on Tables Having Live Aggregate Projections!

Jim Knicely, Vertica Principal Solution Architect
October 17, 2019

A live aggregate projection contains columns with values that are aggregated from columns in its anchor table. When you load data into the table, Vertica aggregates the data before loading it into the live aggregate projection. On subsequent loads (for example, through INSERT or COPY) Vertica recalculates aggregations with the new data and updates the...

Parallel Processing Using Partitions With Vertica UDx

Bryan Herger, Vertica Big Data Solution Architect at Micro Focus
October 17, 2019

You can add functionality to Vertica using UDx, but what if you need to process more data than can be efficiently processed in a single thread or a single node? Vertica can divide data into partitions defined with the OVER() clause and distribute computing across nodes. This partition processing is "shared-nothing" similar to the Map...

Extending Vertica with Python functions: Adding NumPy FFT as a UDx

Bryan Herger, Vertica Big Data Solution Architect at Micro Focus
October 14, 2019

User-Defined Transform Function (UDTF) support for Python UDx were added back in Vertica 9.1, allowing you to add a much greater range of existing libraries and functions to Vertica. In this example, I'll add Fast Fourier Transform (FFT) from the NumPy package. FFT is a way to transform time-domain data into frequency-domain data. My test...

Finding the “K” in K-means Clustering With a UDx

Bryan Herger, Vertica Big Data Solution Architect at Micro Focus
October 4, 2019

You can apply k-means clustering to partition data points into k different groups. Along with the data, the number of clusters "k" is an input to the algorithm. Common examples like the Iris data set tell you upfront how many different groups exist, so you set k=3. What if you don't know how many clusters...
