+## Best Practices
+- For small amounts of data (up to \~200 GB compressed), it is best to use as much memory as the volume of data. For large amounts of data and when processing interactive (online) queries, you should use a reasonable amount of RAM (128 GB or more) so the hot data subset will fit in the cache of pages. Even for data volumes of \~50 TB per server, using 128 GB of RAM significantly improves query performance compared to 64 GB.
+- We should make bulk inserts. Preferably ~ 10000 rows at a time.
