Many product companies make product decisions with a flawed understanding of what’s important to their customers. Focus groups, customer advisory boards, and one-on-one conversations all provide data points to determine customer wants and needs. But these approaches make broad assumptions about your users based upon a limited set of anecdotal evidence.

QUESTION
I have a spring boot java application that talks to cassandra . However one of my queries is failing .
...ANSWER
Answered 2020-Jul-01 at 08:19Without knowing the table schema, my guess is that a change was made to the table so the schema no longer match the bindings in the prepared statement.
A big part of the problem is your query with SELECT *. Our recommendation for best practice is to explicitly name all the columns you're retrieving from the table. By specifying the columns in your query, you avoid surprises when the table schema changes.
In this instance, either a new column was added or an old column was dropped. With the cached prepared statement, it was expecting one column type and got another -- the ArrayList doesn't match UUID.
The solution is to re-prepare the statement and name all the columns. Cheers!

QUESTION
I have a large dataframe consisting of tweets, and keyword dictionaries loaded as values that have words associated with morality (kw_Moral) and emotion (kw_Emo). In the past I have used the keyword dictionaries to subset a dataframe to get only the tweets that have one or more of the keywords present.
For example, to create a subset with only those tweets that have emotional keywords, I loaded in my keyword dictionary...
...ANSWER
Answered 2018-Dec-12 at 14:02Your requirement would seem to lend itself to a matrix type output, where, for example, the tweets are rows, and each term is a column, with the cell value being the number of occurrences. Here is a base R solution using gsub:

I am trying the following command but it didnt work
...ANSWER
Answered 2019-Jun-26 at 14:03Any operation that would require a cluster wide read before write is not supported (as it wont work in the scale that Cassandra is designed for). You must provide a partition and clustering key for an update statement. If theres only 200 records a quick python script or can do this for you. Do a SELECT * FROM mep_primecastaccount and iterate through ResultSet. For each row issue an update. If you have a lot more records you might wanna use spark or hadoop but for a small table like that a quick script can do it.
