            best Jdbc Item reader for large table
            Asked 2021-Jun-15 at 09:05

            I'm currently building an etl pipeline that pulls data from large oracle tables to mongodb, i want to know exactly what's the difference between JdbcCursor Item reader and Jdbc Paging item reader. which one of them is best suited for large tables. are they thread safe ?

            ...

            ANSWER

            Answered 2021-Jun-15 at 09:05

            JdbcCursorItemReader uses a JDBC cursor (java.sql.ResultSet) to stream results from the database and is not thread-safe.

            JdbcPagingItemReader reads items in pages of a configurable size and is thread-safe.

            Asked 2021-Jun-15 at 06:44

            I'm doing some ETL, using the standard "Pre-Load" partition pattern: Load the data into a dated partition of a loading table, then SWITCH that partition into the live table.

            Looks the question was solved by @Larnu's comment, just add it as an answer to close the question.

            If you are using Azure SQL Database, then what the error is telling you is true. Azure SQL Databases are what are known as Partially Contained databases; things like their USER objects have their own Password and the LOGIN objects on the server aren't used for connections. The CONNECTION permission is a server level permission, and thus not supported in Azure SQL Databases.

            I'm trying to collect on my notebook using xperf. The .etl file is generated. i'm using the "Diag" that includes precise and sampled CPU profiles.

            But, when open .etl on WPA, it did not show the "sampled" grap, just precise. Doing some searches, I found this can be related to Hardware Counters used to the sampled timing.

            According to Microsoft, it was caused by Windows Defender:

            We have identified an underlying issue in Windows Defender which we believe to be the root cause for most folks. The fix has already been deployed to Windows Update, the steps to get / verify are below:

            1. From PowerShell run Get-MpComputerStatus Verify AntivirusSignatureVersion is >= 1.341.82.0 a.
            2. If the signature version is < 1.341.82.0 run Windows Update to get the latest version and then reverify
            3. Reboot

            After this profiling should work in ETW based profilers.

            Manually setting AWS Glue ETL Bookmark
            Asked 2021-Jun-03 at 14:38

            My project is undergoing a transition to a new AWS account, and we are trying to find a way to persist our AWS Glue ETL bookmarks. We have a vast amount of processed data that we are replicating to the new account, and would like to avoid reprocessing.

            It is my understanding that Glue bookmarks are just timestamps on the backend, and ideally we'd be able to get the old bookmark(s), and then manually set the bookmarks for the matching jobs in the new AWS account.

            It looks like I could get my existing bookmarks via the AWS CLI using:

            ANSWER

            Answered 2021-Jun-03 at 14:38

            I was not able to manually set a bookmark or get a bookmark to manually progress and skip data using the methods in the question above.

            However, I was able to get the Glue ETL job to skip data and progress its bookmark using the following steps:

            1. Ensure any Glue ETL schedule is disabled

            2. Add the files you'd like to skip to S3

            3. Crawl S3 data

            4. Comment out the processing steps of your Glue ETL job's Spark code. I just commented out all of the dynamic_frame steps after the initial dynamic frame creation, up until job.commit().

            Is it a good practice to use Microsoft power bi for visualizations of a retail data warehouse
            Asked 2021-May-30 at 20:23

            I completed my ETL part in SSIS. Now for data visualization i installed Power BI for dashboards and reports. Also i read research papers and I didn't find anyone related to power Bi. Lastly, Do i need to implement SSAS and SSRS package as well.

            ANSWER

            Answered 2021-Mar-29 at 09:21

            Power BI's strength is data visualisation, and it is likely to be well suited for for using on top of you retail data warehouse.

            I'm not sure which research paper you are referring to, but Microsoft has been topping Gartner's Magic Quadrant for Analytics and Business Intelligence Platform for several years now, followed by Tableau and Qlik. If you are interested in reading further around the various platforms, you can download from https://info.microsoft.com/ww-Landing-2021-Gartner-MQ-for-Analytics-and-Business-Intelligence-Power-BI.html?LCID=EN-US

            Power BI does not require SSAS or SSRS to run. If you already have SSAS, Power BI can use SSAS as a data source, and it works very well with a live connection, alternatively you can model the semantic layer directly within Power BI itself. Power BI, especially now Paginated reports are included is seen as a cloud based alternative to SQL Server Reporting Server

            Because when you use a single revision, you are not comparing with HEAD, you compare with what you have on the working tree.

            Second theory: There was a renamed file so it is displaying the file path for 2 different revisions.
