[AngularJS] Re: data persistence
There are no wildcard searches. The search is based on selecting proper values from over 12 dropdown list. Sql Server is the database. I dont really have an issue except that i dont like current approach of hitting database for every 10 records. I want to be able to hold 1000+ records in memory and show those spread in 100 pages - 10 records per page. and if user wants to see more, then again hit the database to get another/next 1000 records. Front end is Angular, which is calling .Net Rest APIs. These APIs connect to SQL via Entity Framework 6. On Thursday, 8 August 2019 00:19:41 UTC+5:30, Tito wrote: > > Answer this first. > 1.

[AngularJS] Re: data persistence
Its a search based on parameters selected by the user. There are about 10 parameters. Not all searches lead to 2 million but worse case scenarios does. It uses restful API to pull records based on offset so it fetches only 10 records at a time based on page user is on and if user has clicked next or previous. Problem is hitting database on every 10 records. I would like to get about 1000 records at a time and then cache them locally somehow so I can use those to traverse thru those records without hitting the database. In return, this would substantially reduce the database calls. As I am new to Angular, I am not aware of possible features that can help me to implement my idea. Pls suggest if you can think of something.

[AngularJS] data persistence
Hi guys, I am kind of new to Angular and working on already developed Angular 2 + .Net Rest API project. There are quite a few search screens in my project which are getting page by page records. Rest API are getting data from SQL using entity framework. based on search parameters, the record count can go upto 2 million but getting 10 records at one time is slow for two reasons - 1. the data in table is a lot (over 5 millions ) , 2. Hitting database for every 10 records do not make sense. So I want to change all the searches. My idea is to bring about 500 (or 1000) records at once, and persist those records locally somehow. Instead of hitting database on every 10 records, I would like to let user move thru all 500 records ( 50 pages of 10 records each), then hit database for next 500 records. I want to find out whats the best approach for doing this in Angular 2. any guidance will be appreciated.

[AngularJS] Data Persistence
Hi Guys, I am new to Angular and so please excuse if my question is too basic or asked in a wrong way. I need to find a way to optimize Search screens where the data in tables is huge and its expansive to get data from database. The application is Angular 2+ .Net rest API which are using Entity framework to get data from sql database. Current implementation is to hit database for every 10 records, and additionally hit database for getting search count so first time it hits twice. every 10 records, it hits the database for next 10 records for advancing each page. I am hoping for an alternative approach where I could get say 1000 records at once and store them locally to show 100 pages (10 records each), and only moving to 101st page, it should go and hit database to get another 1000 records based on search parameter ofcourse. I am looking for the right way of doing this. any guidance will be appreciated.
