cloudant

问题 I am using Spark Streaming for creating a system to enrich incoming data from a cloudant database. Example - Incoming Message: {"id" : 123} Outgoing Message: {"id" : 123, "data": "xxxxxxxxxxxxxxxxxxx"} My code for the driver class is as follows: from Sample.Job import EnrichmentJob from Sample.Job import FunctionJob import pyspark from pyspark.streaming.kafka import KafkaUtils from pyspark import SparkContext, SparkConf, SQLContext from pyspark.streaming import StreamingContext from pyspark

问题 I've been following the Gather, visualize, analyze and detect anomalies in IoT data tutorial and, although I was able to go through it flawlessly, I'm stuck in the second step of the "Create a data connector to store the historical data" section. In my Watson IoT left menu, there is no entry called "Extensions" , my last option is the "Configuration" one. As far as I know, I have re-checked all the steps twice and I have tried to configure different regions (I'm located in Spain) for both

问题 When using the SDP to extract data from Cloudant and populate dashDB, I occasionally see error messages in the dashdb "XXXX_OVERFLOW" table that look like this: [XXXX does not exist in the discovered schema. Document has not been imported.] Questions What does this error mean? How can I fix it? 回答1: This error is similar to: No matched schema for {"_id":"...","doc":{...}, so the same answer applies here. There are two main phases to the SDP process: Schema analysis Data import In the schema

问题 I'm trying to perform a regex query with cloudant and can't figure out how to do a case and accent insensitive query. I've tried the following (for case insensitive): ^.*((?i)<needle>).*$ but it doesn't work. For the accents (french), I don't even know how to start... 回答1: To do a case insensitive query just add the caseless option when invoking re:run/3 or re:compile/2, e.g.: 18> re:run(<<"abCd">>, <<"c">>, [caseless]). {match,[{2,1}]} I am not sure if accent insensitive queries are

问题 You cannot run any sql statements on a DashDB that result in locks that will conflict with the schema discovery process (SDP) during the initial load. See here for more information: SQLCODE=-911 : "warehouser_error_message": "File <<filename>>.csv.zip could not be loaded due to an exception in dashDB Question : How can I verify if SDP is running the initial load? 回答1: Log in to the Cloudant dashboard and select the _warehouser database. Inside that database, select the document that

问题 I have documents across 2 different databases: fruits, vegetables. It's easier for me to keep the databases separated. Now, suppose I want my user to search from any combination of these databases. Would it work if I run the same query across the three databases, and merge the result. That is: does the order field in a results have an absolute value, or is it relative to the other results? For example: Run my query on fruits db: { total_rows: 2, bookmark: "xxx", rows: [ { id: "Apple", order:
