Ich habe mal eine kleine Datenbank UDF erstellt auf Maps basierend. Ich würde mal sagen: Beta-Status, da ich noch nicht alles auf Herz und Nieren getestet habe.
Die Geschwindigkeit, Einlesen ~500kB CSV Datei (16700) in Datensätze in <1 s gefällt mir. Selbst meine recht rudimentäre Suchfunktion ist relativ flott.
Ich denke, ich werde das noch weiter ausbauen.

#cs FUNCTIONS
About The database is a map. The map stores some administrative keys that are for
internal use only. The datasets are added as a map and the passed
(or automatically generated) ID is their key in the DB map.
_MapDB_New Creates a new database map. Pass the dataset field names as semicolon-separated string or array.
Stores the passed field names inside. Field names are case sensitive!
Returns the map. The number of datasets is indicated by: $myDBMap.Count
The user can add an array of additional database fields. When you remove all
datasets from the DB, you can keep their values or delete the values as well (default).
_MapDB_FromCSV Creates a map database from a passed csv file.
_MapDB_ToCSV Stores a map database as passed csv file.
_MapDB_Add Adds a new dataset. Each field must be assigned a value (empty string if necessary).
- A maximum of 10 single values can be passed as direct parameters.
- Values can also be passed as an array. The number is not limited here, it only
has to match the defined number of fields.
- Values can also be passed as an map. The field names must match the field
names in the database definition.
To make the record unique, an ID must be passed.
If an empty string is passed instead, a consecutive numeric ID is generated.
The return value of the function is the ID.
_MapDB_Modify Modifies one or more values of a dataset.
If data is passed as direct parameters, array or map, an empty string must be passed
for values that are not to be changed. Each field must be assigned a value.
The fourth and certainly most common variant is to pass an assignment string of
the form "field1=value<DELIM>field2=value<DELIM>...".
Opt('GUIDataSeparatorChar') is used as <DELIM>. A sequence or number of values
need not be considered here.
Note!
Field names must be passed in the same notation (case sensitive) as stored
in the database definition.
_MapDB_Remove Removes a dataset or, if an empty ID is passed, all datasets from the database.
Returns the number of deletions.
_MapDB_DSToString Returns field and values of an DS by passed ID as string: "[field1] = value; [field2] = value;... "
_MapDB_DSToArray Returns field and values of an DS by passed ID as 2D array: [[field1,value],[field2,value],...] "
Rudimentary search functions:
_MapDB_SearchAnd Searches with one or more conditions passed as a string like "field1=val<DELIM>field2=val<DELIM>...".
All conditions must match.
Returns a map with one or more datasets matching the conditions.
_MapDB_SearchOr Searches with one or more conditions passed as a string like "field1=val<DELIM>field2=val<DELIM>...".
At least one condition must match.
Returns a map with one or more datasets matching the conditions.

#EndRegionEDIT:
Kein Fehler, aber wenig sinnvoll - keine Ahnung warum ich die interne Funktion __MapCountKeys so kompliziert gestaltet habe.
Hier die korrigierte Version:
AutoIt
Func __MapCountKeys(ByRef $_map)
Return UBound(MapKeys($_map))
EndFuncMann kann natürlich stattdessen direkt die Ubound-Funktion nutzen. Manchmal finde ich es aber sinnvoll, wenn ich beim späteren Lesen anhand des Funktionsnamens sofort die Absicht dahinter erkenne.
