I do not understand. I think you want to do something like

To get correct response from Google server set User-Agent HTTP header:

You can do it by the following steps:

1. Firstly, replace NaN value by empty string (which we may also get after removing characters and will be converted back to NaN afterwards).
2. Cast the column to string type by .astype(str) for in case some elements are non-strings in the column.
3. Replace non alpha and non blank to empty string by str.replace() with regex
4. Finally, replace empty string to NaN by .replace()

(Note: The first 2 steps are to special handle for OP's problem of getting AttributeError: Can only use .str accessor with string values! although my testing of specially adding integer and float (not integer and float in string but real numeric values) also got no problem without the first 2 steps. Maybe some other special data types!?) Other users without the same problem can use only the last 2 steps starting with str.replace().

The problem would be simpler if the data were transposed.

GNU datamash provides such functionality:

You should write a single null byte (0x00) after writing your string to the channel. What you're doing is not it: you're appending the string \x00 instead (a backslash followed by an x and two 0s).

Against my first instincts, it seems it will work if you append the unicode character \u0000 to your string, but the optimal way to do it is simply to put a byte with value 0 into the ByteBuffer after putting your string.

To be clear, I expected the null byte to be doubled when you append \u0000, as Java encodes chars as UTF-16, hence on 2 bytes. But we're explicitly encoding the String to UTF-8 to get it as bytes, so the null char is indeed encoded as a single null byte.

Here's a small demo of this, showing for each method the length of data written to the channel, then its value as bytes:

Here are some simple examples:

The proper way is to use the HTTP 301 status code:

Your container declares that a Docker named volume should be mounted over your application tree:

The JMS specification only states that messages in the same group should be consumed in order. It doesn't say how this functionality should be implemented.

ActiveMQ Artemis implements message grouping by dispatching all the messages in the same group to a single consumer (i.e. what you call "sticky" consumers). However, other JMS providers are free to implement this functionality in other ways.

As noted previously, the only requirement is that messages in the same group are consumed in order. If you've tested this functionality on Oracle AQ and Amazon SQS and have evidence that the messages in the same group are not consumed in order then you should contact those providers for support. It is not valid to simply say that their implementations are different from ActiveMQ Artemis if the ultimate result is the same.
