What's new in Striim 4.1.0

The following features are new in this release.

Sources and targets

• Azure Synapse Writer's MERGE mode performance and reliability have been improved.

• Cobol Copybook Parser can read grouped items.

• Cosmos DB Reader reads from Azure Cosmos DB using its Core (SQL) API (see Azure Cosmos DB using Core (SQL) API).

• Delta Lake Writer for Azure Databricks writes to Azure Databricks.

• Database Reader and Database Writer support Kerberos authentication for Oracle and PostgreSQL (see Enable Kerberos authentication for Oracle and PostgreSQL.

• MongoDB Reader and MongoDB Writer support MongoDB Atlas. When replicating data from MongoDB Reader, MongoDB Writer can handle deletes in the source as deletes in the target. (See MongoDB and MongoDB Writer.)

• Mongo Cosmos DB Reader reads from Azure Cosmos DB using the Azure Cosmos DB API for MongoDB (see Azure Cosmos DB using Cosmos DB API for MongoDB).

• MSJet supports TLS (see MSJet properties).

• OJet offers better performance and other advantages over Oracle Reader (see Oracle Database).

• Oracle Reader supports Kerberos authentication (see Enable Kerberos authentication for Oracle and PostgreSQL).

• Parquet Parser parses Parquet data read by FIle Reader, HDFS Reader, or S3 Reader.

• PostgreSQL Reader supports Kerberos authentication (see Enable Kerberos authentication for Oracle and PostgreSQL).

• Salesforce Reader can read multiple objects, include or exclude custom objects, and adjust its thread pool to match Salesforce's API.

Programming, administration, and operations

• In a multi-server cluster, Automatic load rebalancing can automatically redistribute applications when a server that has been offline comes back online, or when a new server is added to the cluster. (This feature is off by default.)

• Striim 4.1.0 uses the G1 Garbage Collector (previous releases used the Concurrent Mark Sweep (CMS) collector). The monitor and memory utilities may show less free memory than in previous releases, but that is due to G1 freeing memory for use by applications only when it is needed. If you experience memory issues after upgrading to this release, you may switch to CMS by editing startUp.properties to set GC=cms and restarting Striim.

• A HashiCorp vault may be configured to automatically renew its token (see Using vaults).

• Applications can send alerts to Slack (see Sending alerts from applications).
