    Performance Caching in a Snowflake Data Warehouse | killexams.com real questions and Pass4sure dumps

    Like any modern database, Snowflake uses various levels of caching to maximize query performance and reduce disk I/O and machine load. This article provides an overview of the techniques used by Snowflake, the data warehouse built for the cloud.

    System Architecture

    Before starting, it’s worth considering the underlying Snowflake architecture and explaining when Snowflake caches data. The diagram below illustrates the overall architecture, which consists of three layers:

    Image title

  • The Service Layer accepts SQL requests from users, coordinates queries, and manages transactions and results. Logically, this can subsist assumed to hold the result cache, a cached copy of the results of every query executed.
  • The Compute Layer actually does the cumbersome lifting. This is where the actual SQL is executed across the nodes of a Virtual Data Warehouse. This layer holds a cache of data queried, and is often referred to as Local Disk I/O, although in reality this is implemented using SSD storage. All data in the compute layer is temporary and only held as long as the virtual warehouse is active.
  • The Storage Layer provides long-term storage of results. This is often referred to as Remote Disk and is currently implemented on either Amazon S3 or Microsoft Blob storage.
  • Snowflake Caching Layers

    The diagram below illustrates the levels at which data and results are cached for subsequent use:

  • The Result Cache holds the results of every query executed in the past 24 hours. These are available across virtual warehouses, so query results returned to one user are available to every user in the system.
  • The Local Disk Cache caches data used in queries. Whenever data is needed for a given query, it's retrieved from the Remote Disk storage, and cached for subsequent queries here.
  • The Remote Disk holds the long-term storage. This even is accountable for data resilience, which in the case of Amazon Web Services, means 99.999999999% durability, even in the event of an entire data heart failure.
  • Image title

    Benchmark Testing Setup

    Every Snowflake database is delivered with a pre-built and populated set of Transaction Processing Council (TPC) benchmark tables. To test the result of caching, I set up a string of test queries against a minute subset of the data, which is illustrated below.

    Image title

    All the queries were executed on a MEDIUM sized cluster (8 nodes) and joined the tables. The tables were queried exactly as is, without any performance tuning.

    The following query was executed multiple times, and the elapsed time and query arrangement were recorded each time.

    Image title

    The screenshot below illustrates the results of the query which summarise the data by Region and Country. In total, the SQL queried, summarized, and counted 1.5 billion rows of data. The screenshot shows the first eight lines returned.

    Image title

    Test Sequence

    The test sequence was as follows:

  • Run from cold: Starting a fresh virtual warehouse (with no local disk caching), and executing the query.
  • Run from warm: Disabling the result caching and repeating the query. This made employ of the local disk caching.
  • Run from hot: Again, repeated the query, but with the result caching switched on.
  • Each query included over 60Gb of raw data, although as Snowflake was able to automatically compress the data, the actual data transfers were around 12Gb. As Snowflake is a columnar data warehouse, it automatically returns the columns needed rather then the entire row to maximize query performance.

    Run From Cold

    This query returned in around 20 seconds and demonstrates it scanned around 12Gb of compressed data, with 0% from the local disk cache. This means it had no capitalize from disk caching.

    Image title

    The bar chart above demonstrates around 50% of the time was spent on local or remote disk I/O, and only 2% on actually processing the data. Clearly any design changes they can conclude to reduce the disk I/O will attend this query.

    The results moreover demonstrate the queries were unable to fulfill any partition pruning which might improve query performance. We’ll cover the result of partition pruning and clustering in the next article.

    Run From Warm

    This query was executed immediately after, but with the result cache disabled, and it completed in 1.2 seconds – around 16 times faster. In this case, the Local Disk cache (which is actually SSD on Amazon Web Services) was used to return results, and disk I/O is no longer a concern.

    Image title

    In the above case, the disk I/O has been reduced to around 11% of the total elapsed time, and 99% of the data came from the (local disk) cache. While querying 1.5 billion rows, this is clearly an excellent result.

    Run From Hot

    This query returned results in milliseconds and involved re-executing the query, but with this time, the result cache enabled. Normally, this is the default situation, but it was disabled for testing purposes.

    Image title

    The above profile indicates the entire query was served directly from the result cache (taking around 2 milliseconds). Although not immediately obvious, many dashboard applications involve repeatedly refreshing a string of screens and dashboards by re-executing the SQL. In these cases, the results are immediately returned in milliseconds.

    Although more information is available in the Snowflake Documentation, a string of tests demonstrated the result cache will subsist reused unless the underlying data (or SQL query) has changed. As a string of additional tests demonstrated inserts, updates and deletes which don't affect the underlying data are ignored, and the result cache is used, provided data in the micro-partitions remains unchanged.

    Finally, results are normally retained for 24 hours, although the clock is reset every time the query is re-executed, up to a confine of 30 days, after which results query the remote disk.

    Summary

    The sequence of tests was designed purely to illustrate the result of data caching on Snowflake. The tests included:-

  • Raw Data: Including over 1.5 billion rows of TPC generated data, a total of over 60Gb of raw data
  • Initial Query: Took 20 seconds to complete, and ran entirely from the remote disk.  Quite impressive.
  • Second Query: Was 16 times faster at 1.2 seconds and used the Local Disk (SSD) cache.
  • Result Set Query: Returned results in 130 milliseconds from the result cache (intentionally disabled on the prior query).  
  • To reserve the above results in context, I repeatedly ran the same query on Oracle 11g production database server for a tier one investment bank and it took over 22 minutes to complete.

    Finally, unlike Oracle where additional care and exertion must subsist made to ensure revise partitioning, indexing, stats gathering and data compression, Snowflake caching is entirely automatic and available by default.

    Integration between SAP Data Services, trade Warehouse on the rise | killexams.com real questions and Pass4sure dumps

    Because I specialize in the world of SAP trade Warehouse (BW), SAP Data Services was relatively singular to me until a pair of years ago. But since the 4.0 release of Data Services, I've been intrigued by the concept of using it with BW and other SAP applications, allowing both systems to play to their strengths.

    That is to say, SAP Data Services provides excellent and user-friendly transformation capabilities and effortless access to a plethora of viable data sources and targets. On the other hand, SAP BW provides a semantic data warehousing model, advanced hierarchy support, data lifecycle management services, security and more. The combination of Data Services with traditional SAP products dote BW could subsist a powerful solution for many, though there are soundless a pair of pitfalls to subsist vigilant of.

    Improvements in DS 4.0, BW 7.3

    Integration with SAP sources including BW took a broad jump with Data Services 4.0 and was further refined with the recent release of Data Services 4.1.

    The newest version of Data Services can read directly from SAP's "business content" extractors in the ERP, CRM and SRM applications. The table structure in these applications can subsist extremely complex. Extractors act as semantic views on top of these tables and can provide additional capabilities dote delta change capture. This functionality was introduced in Data Services 4.0, and parallel processing was improved in version 4.1.

    Data Services 4.0 moreover supports aboriginal loading of BW DataSource objects, and Data Services is better integrated with BW as a Source System type. This fresh integration makes it very effortless to tow data from Data Services sources directly into BW DataSources, gross from the BW interface. (DataSources is BW's data ingestion construct.) These capabilities are available in BW version 7.3 or later.

    SAP Data Services 4.1 moreover introduces improved parallel loading when using BW's OpenHub tables as a source for Data Services. This is an well-known functionality for many customers because efficiently poignant data out of BW and into other systems for analysis and reporting can subsist a challenge.

    Advantages Data Services can proffer now

    These improvements result in a compelling case for using BW and Data Services together.

    SAP trade Content extractors, originally developed for employ with BW, are the semantic representation of ERP data for analytic uses. Now they are available directly for non-BW employ via Data Services. These extractors should toil without interference even when simultaneously used for BW extraction, and can now subsist used to feed other data marts or an operational data store instead of, or in parallel with, BW loads.

    Data Services is attractive for current BW shops because it is much better at some types of transformations than BW. Pivot transformations, for example, are difficult in BW, often requiring custom-coded routines. In some environments, skills to develop knotty transformations may subsist easier to approach by when developing these transformations in Data Services' custom development language (Python) than in ABAP. Doing custom transformation development in Data Services, rather than BW, may beget custom development more reusable, while reducing the complexity of the BW environment.

    Data Services moreover enables a different software lifecycle management approach. BW changes are often limited to preplanned transport windows every week or month. This ensures a stable system but can subsist problematic for transformation logic that needs to closely track changes in source systems. Segregating source-system-oriented transformations in Data Services could allow a software lifecycle management regime with faster reactions to source-system changes or errors.

    BW soundless has advantages over traditional databases when used as a Data Services data store, and current Data Services shops may want to consider it for this reason. Some of the advantages are outlined in this article comparing the differences between BW and HANA.

    Still some rugged edges

    There are soundless some rugged edges in the Data Services integration with SAP applications and BW. Data Services advocate for trade content extractors is extensive, but it’s limited to extractors for "Operational Data Provisioning," which doesn’t cover every scenario. You can find the replete list of supported extractors in note 1558737 (login is required).

    The integration between BW Source Systems, BW DataSources, Data Services Targets and Data Services Jobs is moreover confusing. When you create a Data Services source system in BW, you can only employ Data Services as a "dumb pipe" to load data to BW. There is no faculty to transform data by using Data Services in this scenario. This approach throws out much of Data Services' power in the cognomen of simplicity.

    However, gross is not lost. If you configure the Data Services connection to BW, and then create a External System source system in BW (instead of a Data Services source system), you can create an arbitrarily structured BW DataSources and BW InfoPackages configuration to rush Data Services jobs of your choosing.

    If the Data Services job's target has the same structure as the BW DataSource, everything works. Surprisingly, the load will toil even if the target of the Data Services job appears to subsist a different DataSource. This is a nice functionality because it allows people to leverage any Data Services transformation logic directly from BW. But it's moreover Dangerous because there are no restrictions forcing you to match structures, though the capability is likely to subsist establish only by more adventurous users.

    Figure 1: Different Source System types for Data Services behave differently in BW. “Data Services” source systems allow you to create DataSources that exactly mirror the structure of a Data Services “Source”. “External System” source systems allow you to create DataSources with capricious structures that are filled using any Data Services Job you choose.

    Data Services can now beget employ of a lot more of the functions that both SAP applications and BW Have to offer. This should beget life a lot easier for those trying to employ Data Services in an environment with other SAP applications, and proffer some especially spellbinding fresh options to BW shops. That said, this is a relatively fresh functionality, so it suffers from bugs and implementation inconsistencies that can subsist confusing. Remaining vigilant of the shortcomings and hidden functionality can ease integration headaches.
