"# 1 Format danych AVRO\n",

"Ćwiczenie ma na celu zademonstrowanie schematów danych AVRO, typów złożonych (mapy, listy, struktury zagnieżdżone) oraz wstęp do Glue / Athena\n",
"\n",
"## Przebieg ćwiczenia\n",
"* skonfiguruj środowisko uruchomieniowe Python (sugerowana Anaconda z Python 3)\n",
"* zainstaluj wszystkie wymagane biblioteki\n",
"\n",
"<code>\n",
"% conda create -n myenv python=3.8\n",
"% conda activate uam-datalake\n",
"% pip install -r ./datalake-uam/jupyter/requirements.txt\n",
"</code>\n",
"\n",
"* zaloguj się do konsoli AWS i stwórz Bucket testowy oraz bazę dancyh w Glue. Uzupełnij poniższy skrypt o te dane \n",
"* wygeneruj dane testowe w wybranym schemacie AVRO\n",
"* zapisz dane do plików na S3 w folderach s3:/<twoj-bukcet-name>/EventName/namespace=xxx/year=YYYY/month=MM/day=DD/version=VVV\n",
"* zarejestruj tabele w Glue z wykorzystaniem BOTO3 / crawler (poprzez konsole AWS GUI - przeglądarkę)\n",
"* skonfiguruj domyślną WorkGroup w Athena (PRIMARY) - konieczne wskazanie miejsce docelowego dla danych z zapytań (S3 location Athena) https://docs.aws.amazon.com/athena/latest/ug/getting-started.html\n",
"* sprawdź definicję tabeli i upewnij się że są zarejestrowane partycje (użyj polecenia MSCK REPAIR w Athena (LOAD PARTITIONS)\n",
"* sprawdź ile danych jest w tabeli (select count(*) from table) - Data Scanned in bytes\n",
"* odpytaj tabele z wykorzystaniem predykatu day=1 (partition elimination) - zweryfikuj ilość danych przeskanowanych (do porównania z ćwiczeniem 2 - parquet)"
