Storage building connections of ship systems and pipelines

The choices available for storing natural gas are limited, particularly for small-scale solutions. For large-scale solutions, on the other hand, there are other solutions available. Pumping gas in under bedrock or salt formations is a case in point. If we do not produce gas on site, we can get the gas to site in three different ways: by truck, ship or pipeline, or using a combination of the three. If you intend to connect your power plant to a gas pipeline, you must answer two simple questions:.

Apache Kafka is a high-throughput distributed message system that is being adopted by hundreds of companies to manage their real-time data. Companies use Kafka for many applications real time stream processing, data synchronization, messaging, and more , but one of the most popular applications is ETL pipelines. Until recently, building pipelines with Kafka has required significant effort: each system you wanted to connect to Kafka required either custom code or a different tool, each new tool used a different set of configurations, might assume different data formats, and used different approaches to management and monitoring.

Data pipelines built from this hodgepodge of tools are brittle and difficult to manage. Kafka Connect is designed to make it easier to build large scale, real-time data pipelines by standardizing how you move data into and out of Kafka. You can use Kafka connectors to read from or write to external systems, manage data flow, and scale the system—all without writing new code. Kafka Connect manages all the common problems in connecting with other systems scalability, fault tolerance, configuration, and management , allowing each connector to focus only on how to best copy data between its target system and Kafka.

Kafka Connect can ingest entire databases or collect metrics from all your application servers into Kafka topics, making the data available for stream processing with low latency. An export connector can deliver data from Kafka topics into secondary indexes like Elasticsearch or into batch systems such as Hadoop for offline analysis.

By using JDBC, this connector can support a wide variety of databases without requiring custom code for each one. Data is loaded by periodically executing a SQL query and creating an output record for each row in the result set. By default, all tables in a database are copied, each to its own output topic, making it easy to ingest entire databases into Kafka.

The database is monitored for new or deleted tables and adapts automatically. When copying data from a table, the connector can load only new or modified rows by specifying which columns should be used to detect changes. The data from each Kafka topic can be partitioned in a variety of ways and is divided into chunks.

If no partitioning is specified, the default partitioner simply organizes data by the Kafka topic and partition. The size of each data chunk can be controlled by the number of records, the amount of time spent writing the file, and schema compatibility. When enabled, the connector automatically creates an external Hive partitioned table for each Kafka topic and updates the table according to the available data in HDFS. We will also demonstrate some useful features of the JDBC and HDFS connectors, such as database change capture, schema migration, and custom partitioning.

The pipeline captures changes from the database and loads the change history into the data warehouse, in this case Hive. In the MySQL database, we have a users table which stores the current state of user profiles. In addition to common user profile information, the users table has a unique id column and a modified column which stores the timestamp of the most recent user profile change. We simulate user profile changes by updating the corresponding entry in the users table.

The data that ultimately ends up in Hadoop will be the edit history of user profiles, ready for analysis using Hive or Spark. Both include Confluent Platform 2. You can either use the prebuilt virtual machine or Vagrant to run the demo. We provide instructions on how to get started with both. To use the prebuilt virtual machine, you need to have Virtualbox or VMware installed.

To use Vagrant, make sure you have vagrant installed. Once Vagrant finishes starting up the virtual machine, you can login into the virtual machine using:. In what follows, all the commands are running in the virtual machine.

The setup. The start. Now we need to create some data in the MySQL database. We will create a users table to represent the user profiles. The autoincrement id column is the primary key and the modified column saves the timestamp of the most recent update of each user profile.

The modified column will be filled with the current timestamp if we omit the value during insert. You should see that the process starts up, logs some messages, and then exports data from Kafka to HDFS.

The related configurations for field partitioning in the HDFS connector are listed in the following table:. In the demo, we used department as the partition field. To check the data in HDFS are actually partitioned by department :. The value part is determined by the department column in the MySQL users table.

The mysql. You can find the detailed documentation for the configuration of these connectors at. Next, we demonstrate how the JDBC connector can perform database change capture. The configurations in the JDBC connector to capture changes are as follows:. In the MySQL users table, the modified column stores the timestamp for last modification of a row.

We change the user profiles by modifying the email column and set modified to current timestamp:. To verify that the modified data is in HDFS:. The two new records matches the new content of the users table in the mysql database. Here we simulate a simple ETL data pipeline from database to data warehouse, in this case, Hive. The data in Hive will be the full history of user profile updates and is available for future analysis with Hive and Spark.

The connector supports schema evolution and reacts to schema changes of data according to the schema. The schema. If a schema is evolved in a backward compatible way, we can always use the latest schema to query all the data uniformly. For example, removing fields is backward compatible change to a schema because when we encounter records written with the old schema that contain these fields we can just ignore them. Adding a field with a default value is another very common backward compatible schema change.

For data records arriving at a later time with schema of an earlier version, the connector projects the data record to the latest schema before writing to the same set of files in HDFS. If Hive integration is enabled, we need to specify the schema.

This ensures that the Hive table schema is able to query all the data under a topic written with different schemas. If the schema. To make a backward compatible change in our source JDBC system, we drop a column in the users table in the database, effectively removing a field from the data. The Avro converter used by Kafka Connect will register a new schema with a higher version in Schema Registry. The HDFS connector detects the schema change and will react according to the schema.

In the demo, we set schema. While it still exists in the old data files, it is ignored by the Hive query because the field is not included in the latest schema. This pipeline captures changes in the database and loads the change history to a data warehouse, in this case Hive. This article show how you can offload data from on-premises transactional OLTP databases to cloud-based datastores, including Snowflake and Amazon S3 with Athena. This release includes a number of key new features and improvements […].

Although starting out with one Confluent Schema Registry deployment per development environment is straightforward, over time, a company may scale and begin migrating data to a cloud environment such as […]. Liquan Pei December 17, Print. Vagrant To use Vagrant, make sure you have vagrant installed. The install script also starts the MySQL server. As Kafka Connect uses Kafka to transfer data, we need to start Kafka. Start Hadoop. The related configurations for field partitioning in the HDFS connector are listed in the following table: partitioner.

In the demo, FieldPartitioner is used, which partitions the data to different directories according to the value of the partitioning field specified in partition.

The configurations in the JDBC connector to capture changes are as follows: mode Specifies how to capture database changes. In the demo, we combine an incrementing column with a timestamp column and incrementing to capture changes. This is the most robust and accurate mode. By combining the two, as long as the timestamp is sufficiently granular, each id, timestamp tuple will uniquely identify an update to a row.

Even if an update fails after partially completing, unprocessed updates will are still correctly detected and delivered when the system recovers. Did you like this blog post? Share it now.

In this article, you learn how to create, publish, run, and track a machine learning pipeline by using the Azure Machine Learning SDK. Use ML pipelines to create a workflow that stitches together various ML phases, and then publish that pipeline into your Azure Machine Learning workspace to access later or share with others. ML pipelines are ideal for batch scoring scenarios, using various computes, reusing steps instead of rerunning them, as well as sharing ML workflows with others. Compare these different pipelines. Each phase of an ML pipeline, such as data preparation and model training, can include one or more steps. ML pipelines use remote compute targets for computation and the storage of the intermediate and final data associated with that pipeline.

Within the liquid petroleum pipeline network there are crude oil lines, refined product lines, highly volatile liquids HVL lines, and carbon dioxide lines CO 2. First, gathering lines are very small pipelines usually from 2 to 8 inches in diameter in the areas of the country where crude oil is found deep within the earth. The larger cross-country crude oil transmission pipelines or trunk lines bring crude oil from producing areas to refineries. There are approximately 72, miles of crude oil system lines usually 8 to 24 inches in diameter in the United States that connect regional markets.

Pipeline network

The Port of Rotterdam has an extensive network of over 1, kilometres of pipelines to transport liquid bulk including crude oil, oil products, chemicals and industrial gases. The pipelines run between companies in the port. There is also a network of pipelines to destinations in the Netherlands, Belgium and Germany. The pipeline network offers a safe, efficient and environmentally-friendly transport solution.

Hydrogen is easy to transport easy in long distance and can be transported in different formats. Today, the transport of compressed gaseous or liquid hydrogen by lorry and of compressed gaseous hydrogen by pipeline to selected locations are the main transport options used. The most common hydrogen transportation means, covering the needs of the different hydrogen markets, are:. Gaseous hydrogen can be transported in small to medium quantities in compressed gas containers by lorry. For transporting larger volumes, several pressurized gas cylinders or tubes are bundled together on so-called CGH 2 tube trailers. The large tubes are bundled together inside a protective frame. The tubes are usually made of steel and have a high net weight.

Cathodic protection CP is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines , where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current. Cathodic protection systems protect a wide range of metallic structures in various environments.

Oil and gas produced from a field need to be transported to customers. On many oil fields, oil is loaded directly on to tankers buoy-loading.
