Snapshot Isolation Delta Lake at Wilma Perry blog

Snapshot Isolation Delta Lake. Concurrent reads and appends are allowed and get snapshot isolation even when they operate on the same delta table partition. Reads can also reach serializable isolation if the. Readers of delta tables use snapshot isolation, which means that they are not interrupted when optimize removes unnecessary files from the. This section describes the supported methods for querying older. Delta lake’s snapshot isolation allows us to expose the ingestion tables to downstream consumers while data is being appended by a streaming job. Databricks recommends using predictive optimization. In terms of isolation, delta lake states it supports serializable isolation for writes and snapshot isolation for reads. Providing snapshot isolation for a set of queries for fast changing tables. This article describes best practices when using delta lake. The isolation level of a table defines the degree to which a transaction must be isolated from modifications made by concurrent transactions.
