Below Changes Need to be done in application.yml file

You can use below

Convert it to list by ast.literal_eval and use explode()to transform each element to a row and also replicate the other columns.

Then, use .apply(pd.Series) to convert dict-like to series.

Finally, concatenate to original dataframe using pd.concat().

Example:

(1) If your computer has enough RAM, then the simplest solution would be along the lines of:

In your regex, there are Unicode property classes whose syntax is not compliant with ECMAScript 2018+ standard, and the named capturing group syntax is different across the two engines. More, since you have to use Unicode property classes in the ECMAScript regex, you need to use the /u flag, and it requires a stricter approach to escaping special chars, so you need to make sure you only escape what you must escape. Besides, \A and \Z / \z anchors are not supported in ECMAScript regex flavor, just use ^ and $.

Here are examples of what is changed:

• Removed the comments as the COMMENT / FREESPACING mode (usually enabled with /x or (?x) flags/options) is not supported in ECMAScript regex
• (?P.*?) => (?.*?) (the P after ? is not supported)
• \pN => \p{N} (the Unicode category name/alias must appear inside curly braces)
• [\-a-zA-Z] => [-a-zA-Z] and \# => # (unnecessary escapes, mandated by the use of /u flag)
• \A => ^ (unsupported anchor)
• \Z => $ (unsupported anchor)

You can use

You have an errant notion regarding document insertion, whether as if the order of insertion with respect to time matters which is to be expected from say an RDBMS like MS/SQL, or a belief that a string representation of a numeric value should be sorted according to the implied numerical value (which would be wild guessing by the db).

As explicitly stated here, here and here, and as specified by the CouchDB documentation 3.2.2.5. Collation Specification

Comparison of strings is done using ICU which implements the Unicode Collation Algorithm, giving a dictionary sorting of keys. This can give surprising results if you were expecting ASCII ordering.

Documents are not returned by order of insertion rather they are returned according to the collation rules applied to the document ids, and document ids are strings.

For example you expect this ordering:

BUT that is not according to the collation rules, which yields

Again, it cannot be emphasized enough that the order of insertion, much less an implied numeric value, does not affect the order of results. From an RDBMS perspective it is helpful to approach _all_docs results as being ordered by an index on _id which is sorted according to collation rules (again, for strings since all _ids are of type string).

The snippet below demonstrates this by creating 100 documents with ids ranging from 1 to 100.

You can avoid this problem if you unregister the previous watch setup for the renamed directory. When renaming, you get a DELETE then CREATE for the parent's folder watch, so you can amend the watched directories to cancel the old key, and register a new key.

Here is your main with small adjustments for logging the keys in use and handling the delete + create using a HashMap to keep track of directories added to the watch service:

Condition !line.contains("") - doesn't make sence because every string contains empty string.

General suggestions:

• don't hard code file-path, code must be reusable;
• use try with resources;
• camel-case names.
