1 00:00:00,810 --> 00:00:09,780 I hope you are able to figure out a possible approach to update the clouds which is next on the fly. 2 00:00:11,100 --> 00:00:14,520 Solution is simple very simple. 3 00:00:14,550 --> 00:00:23,560 And we have used this process already a couple of times in this course and you might have already guessed 4 00:00:23,560 --> 00:00:24,110 it. 5 00:00:24,440 --> 00:00:33,900 We're going to is dynamo Davies dreams along with Louderback trigger to upload the changes to Klaus's. 6 00:00:34,190 --> 00:00:35,280 So let's do that. 7 00:00:40,820 --> 00:00:49,200 Our Global TV stable already has streams and Nabl with old and new images. 8 00:00:49,490 --> 00:00:58,220 We just need to create a new land at Treanor to upload the changes to cloud search said let's create 9 00:00:58,220 --> 00:00:59,100 a new folder 10 00:01:01,740 --> 00:01:08,980 open it the code and let's initialize a new mode project with NPR and 11 00:01:12,060 --> 00:01:14,210 just like that. 12 00:01:14,410 --> 00:01:18,380 Install a business SDK as usual 13 00:01:21,610 --> 00:01:29,430 create an index or just fine to hold our land function inside the file reference. 14 00:01:29,480 --> 00:01:31,810 The as the. 15 00:01:44,640 --> 00:01:46,800 And initialize an object. 16 00:01:46,840 --> 00:01:49,680 Our Lives SEAGE to make less 17 00:01:55,230 --> 00:01:56,220 this time. 18 00:01:56,220 --> 00:02:05,520 The End Point is going to be the document and point and not the search point because we want to upload 19 00:02:05,520 --> 00:02:16,030 documents to ourselves and Mark actually from the searches said Copy the document and point from cloud 20 00:02:16,030 --> 00:02:20,460 search console and pasted in here. 21 00:02:21,790 --> 00:02:28,210 Then let's write the handler function for lambda a space dog handler. 22 00:02:28,560 --> 00:02:40,140 You rant on text and call the and the dynamo these three red cards will be available in the event. 23 00:02:40,160 --> 00:02:48,640 Dark red cards at the age of 10 when the intervening item data in a format are required by a large search 24 00:02:48,700 --> 00:02:49,540 API. 25 00:02:50,540 --> 00:02:54,330 And we can do that using the map function. 26 00:02:54,440 --> 00:03:06,800 Max function simply is a custom function on every element of an entity and it is a new we are going 27 00:03:06,800 --> 00:03:14,460 to use the asynchronous version of the map function using the a saying and more. 28 00:03:14,570 --> 00:03:23,050 You said let's install a sing using and install a single dash dash. 29 00:03:23,120 --> 00:03:28,200 Save and then run city code 30 00:03:33,070 --> 00:03:38,380 then inside the Landauer handler we can call the map method 31 00:03:42,280 --> 00:03:49,730 a saying door map B and A which is event to dart cars. 32 00:03:49,750 --> 00:03:57,020 In our case I already function that takes in car and call back 33 00:04:00,000 --> 00:04:01,740 let's call it call back. 34 00:04:01,740 --> 00:04:14,240 Matt just to differentiate it from the main call that then the final callback are the function louses 35 00:04:14,360 --> 00:04:19,550 API provides two operations add and delete. 36 00:04:19,610 --> 00:04:31,220 We use the add to add new documents or to update existing ones and then later remove existing documents 37 00:04:31,220 --> 00:04:34,630 from the clouds in less. 38 00:04:34,640 --> 00:04:44,430 So for each record we specify the operation type on the or delete followed by the unique ID of the document. 39 00:04:45,460 --> 00:04:56,470 And then the data base ascii value is in case there is see or room event from this train we issue a 40 00:04:56,520 --> 00:05:02,480 delete operation as we issue an ad operation. 41 00:05:02,550 --> 00:05:13,190 Now if you run a search on Blough search you will notice that allowed search generates a unique ID. 42 00:05:13,210 --> 00:05:24,120 We are trying to move the item using the primary key to partition key and hash key separated by an underscore 43 00:05:24,130 --> 00:05:24,970 correct. 44 00:05:27,400 --> 00:05:37,070 So in our function we must force the ID in the same format say for a car door event name equals the 45 00:05:37,110 --> 00:05:37,900 No. 46 00:05:38,110 --> 00:05:51,700 Then we turn the call back map with an object with type delete and tidy as user ID and time stamp call 47 00:05:51,800 --> 00:05:59,280 calculated by an honest less populated user ID and time. 48 00:06:16,170 --> 00:06:17,700 Just like that. 49 00:06:23,020 --> 00:06:36,150 In the event name is anything Bartiromo we issue an the races in that as long callback map and return 50 00:06:36,150 --> 00:06:50,250 the object with type and an ID as ID and the leaves to add licet these is an object with key value pairs 51 00:06:50,310 --> 00:07:01,470 are dynamo Leavey item attributes Bede's should be a rainbow in the new image attribute in the event 52 00:07:01,470 --> 00:07:02,310 stream. 53 00:07:02,340 --> 00:07:14,480 So let's declare a variable to point to new image and then we can use it to populate all the item to 54 00:07:14,490 --> 00:07:24,860 use these will be the column names from Blauser and Raley's will be the corresponding Raley's from the 55 00:07:24,860 --> 00:07:26,830 dynamo the item 56 00:08:02,940 --> 00:08:12,420 now we should have the resulting batch of documents to be uploaded rentable in the SOS object in the 57 00:08:12,420 --> 00:08:13,910 final callback. 58 00:08:15,830 --> 00:08:28,280 The last step is to call the upload documents method or the cloud system and class so see as the dot 59 00:08:28,560 --> 00:08:32,360 load documents caroms callback 60 00:08:43,300 --> 00:08:49,840 and inside the parents we have to specify Content-Type applications. 61 00:08:49,900 --> 00:08:50,650 Jason 62 00:08:56,590 --> 00:09:05,290 and document that would be the results object converted to Jason using Jason. 63 00:09:05,320 --> 00:09:06,710 There are springeth 64 00:09:12,820 --> 00:09:17,220 Arlanda operation is ready let's create a package. 65 00:09:17,260 --> 00:09:22,310 As usual then the contents of the folder 66 00:09:26,770 --> 00:09:33,560 and then remove the age of us as the Kapler ran inside the margins for 67 00:09:39,540 --> 00:09:42,170 open the dynamo console. 68 00:09:42,180 --> 00:09:49,240 And on that triggers tab key to the new fashion. 69 00:09:49,510 --> 00:09:53,380 And it take us to the land console. 70 00:10:09,780 --> 00:10:15,720 I'm going to name the function as a date cloud sewage from Diabaly 71 00:10:18,560 --> 00:10:20,490 we'll create a new role. 72 00:10:23,410 --> 00:10:26,810 Call it land or cloud message. 73 00:10:26,890 --> 00:10:27,240 Dan 74 00:10:30,620 --> 00:10:33,850 Roop policy document and they did. 75 00:10:33,950 --> 00:10:42,650 And I'm going to Baystate and Jason policy right Grant permission to land are allowed to charge a large 76 00:10:42,760 --> 00:10:54,470 surge and ultimately the Danimal streams I have attached the policy Jason document in the sources section 77 00:10:54,560 --> 00:10:57,930 of this video for your use as well. 78 00:10:59,490 --> 00:11:02,920 And enable the trigger and a function 79 00:11:08,380 --> 00:11:11,540 and then we simply upload our code here. 80 00:11:18,680 --> 00:11:31,510 Let's increase the timeout 2 to 1 minute and save the function. 81 00:11:31,610 --> 00:11:35,870 Now to test if this works I'm going to delete. 82 00:11:35,890 --> 00:11:48,270 Am I to duplicate any existing item and also modify an existing item to see if the change reflects in 83 00:11:48,290 --> 00:11:55,360 clouds which an ongoing in the user id be formulating. 84 00:11:55,740 --> 00:12:08,470 And then this item that's duplicated is and change the partition key to some random data. 85 00:12:08,650 --> 00:12:12,480 Note the new p. 86 00:12:12,640 --> 00:12:16,310 And then let's also modify another item. 87 00:12:24,810 --> 00:12:29,150 And neighed the partition key is that. 88 00:12:29,370 --> 00:12:30,000 All right. 89 00:12:30,130 --> 00:12:31,540 Let's see. 90 00:12:31,660 --> 00:12:41,940 The land functions if you did all that Krieger's stab hits with fresh and you can see that last result 91 00:12:42,090 --> 00:12:44,960 was successful. 92 00:12:45,080 --> 00:12:48,460 And if you look at cloud watch longs 93 00:12:51,380 --> 00:12:59,240 we see that one item was deleted and two were added are dated. 94 00:12:59,750 --> 00:13:03,870 Let's finally verify this from Plow's search. 95 00:13:03,870 --> 00:13:09,390 Consul the first search for the delete key. 96 00:13:09,390 --> 00:13:18,020 Now we see that there are no reasons searching by the other two. 97 00:13:18,030 --> 00:13:21,970 He should give us the latest results. 98 00:13:25,480 --> 00:13:26,200 And 99 00:13:32,830 --> 00:13:43,230 what Austin said that able to update our search results on the fly using diamante these screams and 100 00:13:43,350 --> 00:13:49,800 land outriggers that completes our them or our search. 101 00:13:49,810 --> 00:13:56,390 Next up is cloud watch and we're very familiar with cloud watch. 102 00:13:56,600 --> 00:14:00,110 There is a lot in this course. 103 00:14:00,630 --> 00:14:08,980 Yes in the next section we're going to take a closer look at the cloud what there is and use it more 104 00:14:09,070 --> 00:14:10,370 effectively.
