4. Common Developer Tasks for Impala

John Russell O'Reilly Media ePub

Here are the special Impala aspects of some standard operations familiar to database developers.

Because Impala’s feature set is oriented toward high-performance queries, much of the data you work with in Impala will originate from some other source, and Impala takes over near the end of the extract-transform-load (ETL) pipeline.

To get data into an Impala table, you can point Impala at data files in an arbitrary HDFS location; move data files from somewhere in HDFS into an Impala-managed directory; or copy data from one Impala table to another. Impala can query the original raw data files, without requiring any conversion or reorganization. Impala can also assist with converting and reorganizing data when those changes are helpful for query performance.

As a developer, you might be setting up all parts of a data pipeline, or you might work with files that already exist. Either way, the last few steps in the pipeline are the most important ones from the Impala perspective. You want the data files to go into a well-understood and predictable location in HDFS, and then Impala can work with them.

CHAPTER 19

Nathan Shedroff Rosenfeld Media ePub

As stated in the introduction, design is both part of the problem and part of the solution to sustainability agendas. The history of design is inconsistent in terms of impacts, both positive and negative, along social, environmental, and financial criteria. Designers and developers have created amazing and wonderful things for the world and for people. Unfortunately, weve also created some solutions that have hurt people and the environment in a myriad of ways. However, this doesnt have to be the future of design.

We dont get to create meaning or change society very often, and we need to set realistic expectations about how long change takes and what part we can play in it. Were neither the only cultural actors nor the most influential. How-ever, because were involved in the process of creating new solutions, communications, and understandingsat significant pointswe can have considerable influence if we choose to use it.

Designers need to decide which values they want to reinforce. There will always be a market for styles based on trends and fads. Its up to each of us, however, to decide to what extent we want to support these and how appropriate they are. The same goes for cultural messages we respond to and reinforce.

Chapter One: Remembering

Meg Harris Williams Karnac Books ePub

The Long Week-End

Wilfred Bion’s The Long Week-End is a fascinating account of one man’s failure to become an individual, to achieve integrity, to make emotional contact with his internal objects. It is remarkable in that it is a well-written, witty, artistic evocation of an apparently unprepossessing subject. It works on the lines of the questions posed in his Memoir of the Future: “Has anyone seen an artist paint a picture ‘about’ or ‘of something ugly which was nevertheless beautiful?” (Bion, 1991, p. 128). The genre of the work might be described as a hybrid drawn from Goodbye to All That, Lord of the Flies, and 1984. For although its effect depends on the realistic description of a particular social climate, it has a futuristic quality which makes an essential contribution to its emotional impact. In the religion, prudery, and patriotism of the late Victorian age, one glimpses Big Brother in the form of a series of “false parents”, of perverse ideals of masculinity and femininity and education. These, despite the good and even loving intentions of several of the main characters, succeed in divorcing the child Wilfred from any genuine emotional contact with his parents (literal and metaphorical), or with his cultural heritage. “The parents, staff, all were caught in a web of undirected menace” for “Who could recognise danger in piety, ardent patriotism to school and games heroes?” (Bion, 1982, pp. 47, 92). As a child, Wilfred has yet to learn that the prep-school bully, Morgan, is not unique but an archetype; and “there were plenty more where that one came from, the source of the Morgans of this life” (ibid., pp. 47-50). And Bion occasionally slips in, in parentheses, other remarks to remind us that the sinister “web” of that period continues in modern forms. But the main key to the present and future relevance of the book lies in our seeing it as an account of the failure of growth of an Everyman. As Bion brings to notice in his Preface, “Anyone can ‘know’ which school, regiment, colleagues, friends I write about. In all but the most superficial sense they would be wrong. I write about ‘me’”. For, in writing about “me”, he recognizes that he is “more likely to approximate to [his] ambition” of formulating “phenomena as close as possible to noumena” (p. 8).

SIX The Individualist Action-Logic: Bridge to transforming leadership

William R. Torbert Berrett-Koehler Publishers ePub

In Chapters 1 through 3, we said that action inquiry centers on a process of learning. This learning process is not a mechanistic, automated feedback process producing continuous change, but is instead a bumpy, discontinuous, sometimes upending, and transformational kind of learning. This learning affords individuals and organizations a widening and deepening of vision and new capacities for learning from single-, double-, and triple-loop feedback in the moment of action.

In Chapters 4 and 5, we began to illustrate this bumpy lifetime learning process. Virtually every person goes through several action-logic transformations during early life. We begin life in a stage we call the Impulsive action-logic, which we do not discuss in this book. The vast majority of us transform from the Impulsive action-logic to the Opportunist action-logic sometime between the ages of 3 and 6. A very large majority of us proceed to transform from Opportunist to Diplomat, usually between the ages of 12 and 16. A certain proportion of us transform to the Expert action-logic by the time we are 21. Many more of us do so during the decade after we join the workforce.
