+The proposal of this work is to compare the speed in read/writing a midle level of data (a dataset with 9 columns and 1.000.000 lines) to seven diferent databases:
 * ClickHouse
 * InfluxDB
 * Postgresql
 * Parquet (in a S3 Minio Storage)<br>
-ToDo:
-* DuckDB with Polars
+* DuckDB 
 * MongoDB
 * Kdb+

-Deve-se relevar:
-é uma "cold-storage" ou  "frezze-storage"? <br>
-influxdb: alta leitura e possui a vantagem da indexaçõa para posterior vizualização de dados em gráficos
-
-notas: 
-* comparar tamanho do csv com parquet
