kandi X-RAY | reindexer Summary
Reindexer is an embeddable, in-memory, document-oriented database with a high-level Query builder interface. Reindexer's goal is to provide fast search with complex queries. We at Restream weren't happy with Elasticsearch and created Reindexer as a more performant alternative. The core is written in C++ and the application level API is in Go. This document describes Go connector and its API. To get information about reindexer server and HTTP API refer to reindexer documentation.

QUESTION
I have a pandas df that contains the following data:
...ANSWER
Answered 2021-Feb-16 at 01:12There's a few ways to do this but this is the simplest. I'm defining the function outside of the apply operation for readability's sake.
QUESTION
Here I'm adding time to data where only date is given. There are 5 minutes between values or 288 values per date.
The code works when the input dataframe is 1 day (288 rows) or less, but gives an error when the input is longer. Any idea what I'm missing? Thanks in advance.
Relevant section of code:
...ANSWER
Answered 2020-Feb-12 at 20:03You get the KeyError: 'date'
because it is not being passed in the function when you use apply()
after the groupby. You try for example adding a lambda to the apply. I'm not sure about the intended behavior, but it gets the function working. Change it to this:
QUESTION
MarkLogic - 9.0.8.2
We have around 5 indexes created which are used to search data (19M records) within MarkLogic
Now we want to add one more index, resource utilization will be depend on value defined in reindexer throttle (Large numbers mean work more harder reindexing)
As reindexing will take few hours/days to finish it up in production environment and should not have impact to performance on production environment, we followed (reindexer enable false during business hours) best practices suggested by MarkLogic.
MarkLogic Best Practices for Reindexing
Now my question is, with Reindexing disabled, will adding new data will be indexed for existing indexes which were created initially?
...ANSWER
Answered 2019-Dec-04 at 14:42The reindexer setting applies only to the updating of existing data following configuration changes. With or without reindexing enabled, newly inserted data will be indexed with the configuration that is active during the insert.
In many cases this means that index changes should be applied in multiple steps: first, adding any new indexes required by the application, then deploying code with dependencies to those indexes after reindexing is complete, and finally removing any indexes made obsolete by the deployed code.
QUESTION
The function below works fine when I run it in a single data set but it doesn't work in multiple data sets. I am not sure if I am doing anything wrong with the iteration.
ValueError: cannot reindex from a duplicate axis
Any help will be appreciated.
...ANSWER
Answered 2019-Oct-29 at 16:12I don't think this problem is occurring specifically because you're trying to scan multiple sheets in a document. I think the problem is with the data itself, and the error could have just as easily occurred in your single data set.
Looking at your Excel file, I think the problem is that both sheets have two rows with the datetime 8/27/2019 10:30:00 PM
. I think df.set_index('dtime').asfreq('-30T')
only works if the dtime column contains no duplicates. Try removing duplicates beforehand, either by manually editing the data or by dropping duplicates from the dataframe.
QUESTION
I'm trying to use std::map with a custom class and in the course of the process the program has to call std::map::find in order to resolve a key to a pair. The custom class doesn't seem to fit well in terms of comparisons.
This is probably better explained in code; I have a class that I want to use as a key:
...ANSWER
Answered 2019-Aug-09 at 06:57You have to define a strict order to use class index_t
as key in a std::map
.
It doesn't need to make sense to you – it just has to provide a unique result of less-than for any pairs of index_t
instances (and to grant a < b && b < c => a < c).
The (in question) exposed attempt doesn't seem to fulfil this but the following example would:
QUESTION
I have a pandas dataframe with one column of model variables and their corresponding statistics in another column. I've done some string manipulation to get a derived summary table to join the summary table from the model.
lost_cost_final_table.loc[lost_cost_final_table['variable'].str.contains('class_cc', case = False), 'variable'] = lost_cost_final_table['variable'].str[:8]
Full traceback.
...ANSWER
Answered 2019-May-03 at 19:15The index of lost_cost_final_table
is not unique, which can be fixed by running reset_index

QUESTION
I have a Magento 2 website and require some direction with setting up sub-category urls to be SEO friendly. The Navigation menu work just fine i.e
Grooming Kit
www.mywebsite.com/product-grooming-kit.html the issue i'm having is with sub-categories in the left sidebar filters which when a specific category is clicked on it displays as following url with a number id
www.mywebsite.com/product-grooming-kit.html?grooming-kit=32
I want it to look like
www.mywebsite.com/product-grooming-kit/grooming-kit-mens/
I have added this to custom urls manually, cleared cache and still no changes?
In Magento 1.9 i would do a reindexer using ssh and would update urls. Not sure how to do this in Magento 2 without installing a third party extension.
Any help would be much appreciated.
Many Thanks Vinnie
...ANSWER
Answered 2018-Dec-18 at 09:45please look at:
system->config->catalog->seo->use category paths in product url->yes
and then also important: system->config->catalog->seo->canonical for categories/products->yes
For the URL Rewrites, you should use an extension. I recommend OlegKoval_RegenerateUrlRewrites but only if you are using a version up to Magento 2.2.4. Then you should use OlegKoval_RegenerateUrlRewrites Version 1.3.0.
Please look also at a SEO extension that resolves the duplicate content issue if you are using multiple store views for different languages. (Maybe this one).
