AVB accelerates search in LINQ with Amazon OpenSearch Service

This put up is co-written with Mike Russo from AVB Advertising.

AVB Advertising delivers customized digital options for his or her members throughout a variety of merchandise. LINQ, AVB’s proprietary product data administration system, empowers their equipment, client electronics, and furnishings retailer members to streamline the administration of their product catalog.

A key problem for AVB’s members is the flexibility to retrieve, kind, and search via product knowledge, which is essential for gross sales actions inside their shops. Flooring gross sales use AVB’s Hub, a customized in-store buyer relationship administration (CRM) product, which depends on LINQ. Initially, searches from Hub queried LINQ’s Microsoft SQL Server database hosted on Amazon Elastic Compute Cloud (Amazon EC2), with search occasions averaging 3 seconds, resulting in diminished adoption and unfavorable suggestions.

On this put up, we share how AVB diminished their common search time from 3 seconds to 300 milliseconds in LINQ by adopting Amazon OpenSearch Service whereas processing 14.5 million report updates every day.

Overview of resolution

To satisfy the calls for of their customers, the LINQ staff set a objective to cut back search time response to beneath 2 seconds whereas supporting retrieval of over 60 million product knowledge information. Moreover, the staff aimed to cut back operational prices, cut back administrative overhead, and scale the answer to satisfy demand, particularly throughout peak retail durations. Over a 6-month interval, the staff evaluated a number of structure choices, ultimately shifting ahead with an answer utilizing OpenSearch Service, Amazon EventBridge, AWS Lambda, Amazon Easy Queue Service (Amazon SQS), and AWS Step Features.

Throughout implementation, the LINQ staff labored with OpenSearch Service specialists to optimize the OpenSearch Service cluster configuration to maximise efficiency and optimize value of the answer. Following the finest practices part of the OpenSearch Service Developer Information, AVB chosen an optimum cluster configuration with three devoted cluster supervisor nodes and 6 knowledge nodes, throughout three Availability Zones, whereas protecting shard measurement between 10–30 GiB.

Updates to the first LINQ database come from numerous sources, together with associate APIs for producer metadata updates, LINQ’s frontend, and LINQ PowerTools. A Lambda operate reads the updates from change knowledge seize (CDC) tables on a schedule, which sends the up to date information to a Step Features workflow. This workflow prepares and indexes the report into OpenSearch Service in JSON format, permitting for particular person customizations of the report on a per-customer foundation. The LINQ staff exposes entry to the OpenSearch Service index via a search API hosted on Amazon EC2. The next determine outlines the answer.

Overview of the solution

AVB developed the LINQ Product Information Search resolution with the experience of a various staff together with software program engineers and database directors. Regardless of their restricted expertise with AWS, they set a timeline to finish the mission in 6 months. AVB had a number of objectives for this new workload, together with search APIs to assist in-store gross sales flooring associates’ capability to shortly discover merchandise primarily based on buyer necessities, scalability to assist future development, and real-time analytics to assist AVB’s wants round understanding their knowledge.

AVB break up this mission into three key phases:

  • Analysis and improvement
  • Proof of idea
  • Implementation and iteration

Analysis and improvement

AVB’s LINQ staff acquired a process to determine essentially the most environment friendly resolution to expedite product searches throughout AVB’s suite of software program merchandise. The staff accomplished a complete analysis of assorted applied sciences and methods to satisfy their necessities, together with a detailed examination of assorted NoSQL databases and caching mechanisms. Following this exploration, AVB chosen OpenSearch Service, an open supply, distributed search and analytics suite, to be used in a proof of idea. AVB selected OpenSearch Service for its highly effective search capabilities, together with full-text search and sophisticated question assist, in addition to its capability to combine seamlessly with different AWS providers.

Proof of idea

Within the proof of idea section, the AVB staff centered on validating the effectiveness of their chosen expertise stack, with a specific emphasis on knowledge loading and synchronization processes. This was important to attain real-time knowledge consistency with their major system of report to supply right and up-to-date data to flooring gross sales brokers. A big a part of this section concerned the modern course of of information flattening, a method essential for managing complicated product knowledge.

For instance, let’s discover a use case of a fridge listed within the SQL Server database. This product is linked to a number of associated tables: one for primary particulars like mannequin quantity and producer, one other for pricing, and one other for options comparable to power effectivity and capability. The unique database shops parts individually however linked via relational keys. The next determine gives an instance knowledge schema of the SQL Server database.

Microsoft SQL Server Schema

To reinforce search capabilities in OpenSearch Service, the staff merged all these disparate knowledge parts right into a single, complete JSON doc. This doc contains each customary producer particulars and member-specific customizations, like particular pricing or extra options. This leads to an optimized report for every product for fast and environment friendly search in OpenSearch Service. The next determine exhibits the info schema in OpenSearch Service.

Amazon OpenSearch Service Schema

Reworking relational knowledge right into a consolidated, searchable format allowed the LINQ staff to ingest the info into OpenSearch Service. Within the proof of idea, AVB shifted to updating knowledge through the use of reference IDs, that are straight linked to the first IDs of the product information or their relational entities within the SQL database. This strategy permits updates to be executed independently and asynchronously. Crucially, it helps non-first in, first out (FIFO) processing fashions, that are very important in high-scale environments prone to knowledge discrepancies like drops or replays. Through the use of reference IDs, the system fetches essentially the most present knowledge for every entity on the time a change happens, guaranteeing that the most recent knowledge is all the time used when processed. This methodology maintains knowledge integrity by stopping outdated knowledge from superseding newer data, thereby protecting the database correct and present. A noteworthy method used within the proof of idea was index aliases, permitting for zero downtime re-indexes for including new fields or fixing bugs. AVB constructed sturdy efficiency monitoring and alerts utilizing Amazon CloudWatch and Splunk, which enabled swift identification of points.

The proof of idea improved search relevance by flattening relational knowledge, which improved indexing and queryability. This restructuring diminished search response latency to 300 milliseconds, which was properly beneath the 2-second objective set for this proof of idea. With this profitable proof of idea demonstrating the effectiveness of the architectural strategy, AVB moved on to the following section of implementation and iteration.

Implementation and iteration

With AVB exceeding their preliminary objective of lowering search latency to beneath 2 seconds, the staff then adopted an iterative strategy to implement the whole resolution, with a sequence of deployments designed to make knowledge accessible in OpenSearch Service from completely different enterprise verticals. Every enterprise vertical has information consisting of various attributes, and this incremental strategy allowed AVB to herald and examine knowledge to ensure the paperwork in OpenSearch Service are what the staff anticipated. Every deployment centered on particular knowledge classes and included refinements to the indexing course of from classes discovered in prior deployments. AVB additionally locations a robust emphasis on value optimization and safety of the answer, and deployed OpenSearch Service into a personal VPC to permit strict entry management. Entry to the brand new search capabilities is managed via their Hub product utilizing a middleware service offered by LINQ’s API. AVB makes use of sturdy API keys and tokens to supply API safety to the brand new search product. This systematic development meant that the finished LINQ Product Information Search catalog met AVB’s pace and accuracy necessities.


On this put up, you discovered how AVB diminished their common search time from 3 seconds to 300 milliseconds in LINQ by adopting OpenSearch Service whereas processing 14.5 million report updates every day, leading to a 500% enhance in adoption by AVB’s inner groups. Tim Hatfield, AVB Advertising’s VP of Engineering, mirrored on the mission and said, “By partnering with AWS, we’ve not solely supercharged Hub’s search speeds but in addition solid a cost-efficient basis for LINQ’s future, the place swift searches translate into diminished working prices and keep the aggressive edge in retail expertise.”
