Parameters:
executeCosmosBatch
public Mono
Executes the transactional batch.
Parameters:
Returns:
If the transactional batch executes successfully, the value returned by CosmosBatchResponse#getStatusCode on the response returned will be set to 200}.
If an operation within the transactional batch fails during execution, no changes from the batch will be committed and the status of the failing operation is made available by CosmosBatchResponse#getStatusCode or by the exception. To obtain information about the operations that failed in case of some user error like conflict, not found etc, the response can be enumerated. This returns CosmosBatchOperationResult instances corresponding to each operation in the transactional batch in the order they were added to the transactional batch. For a result corresponding to an operation within the transactional batch, use CosmosBatchOperationResult#getStatusCode to access the status of the operation. If the operation was not executed or it was aborted due to the failure of another operation within the transactional batch, the value of this field will be 424; for the operation that caused the batch to abort, the value of this field will indicate the cause of failure.
If there are issues such as request timeouts, Gone, session not available, network failure or if the service somehow returns 5xx then the Mono will return error instead of CosmosBatchResponse.
Use CosmosBatchResponse#isSuccessStatusCode on the response returned to ensure that the transactional batch succeeded.
executeCosmosBatch
public Mono
Executes the transactional batch.
Parameters:
Returns:
If the transactional batch executes successfully, the value returned by CosmosBatchResponse#getStatusCode on the response returned will be set to 200}.

Returns:
openConnectionsAndInitCaches
@Deprecated
public Mono
Deprecated
Best effort to initialize the container by warming up the caches and connections for the current read region.
Depending on how many partitions the container has, the total time needed will also change. But generally you can use the following formula to get an estimated time: If it took 200ms to establish a connection, and you have 100 partitions in your container then it will take around (100 * 4 / CPUCores) * 200ms to open all connections after get the address list
NOTE: This API ideally should be called only once during application initialization before any workload. In case of any transient error, caller should consume the error and continue the regular workload.
Returns:
openConnectionsAndInitCaches
@Deprecated
public Mono
Deprecated
Best effort to initialize the container by warming up the caches and connections to a specified no. of regions from the preferred list of regions.
Depending on how many partitions the container has, the total time needed will also change. But generally you can use the following formula to get an estimated time: If it took 200ms to establish a connection, and you have 100 partitions in your container then it will take around (100 * 4 / (10 * CPUCores)) * 200ms * RegionsWithProactiveConnections to open all connections after get the address list
NOTE: This API ideally should be called only once during application initialization before any workload. In case of any transient error, caller should consume the error and continue the regular workload.
In order to minimize latencies associated with warming up caches and opening connections the no. of proactive connection regions cannot be more than CosmosContainerProactiveInitConfigBuilder#MAX_NO_OF_PROACTIVE_CONNECTION_REGIONS.
