Can I access Delta tables outside of Databricks Runtime?

[User16826994223]

Is it possible to write same table with Databricks and from OSS too, Also what if I want to read the data from Map redeuce or hive

[User16826994223]

There are two cases to consider: external writes and external reads.

• External writes: Delta Lake maintains additional metadata in the form of a transaction log to enable ACID transactions and snapshot isolation for readers. In order to ensure the transaction log is updated correctly and the proper validations are performed, writes must go through Databricks Runtime.
• External reads: Delta tables store data encoded in an open format (Parquet), allowing other tools that understand this format to read the data. For information on how to read Delta tables, see Integrations.

Yes. The Delta client is open source, and lets you read/write Delta tables if you add it to your external application. See https://docs.delta.io/latest/index.html
