Oscar Korz updated BEAM-3569: ----------------------------- Fix Version/s: 2.3.0 Looks like this was fixed in 2.3.0, thanks. https://github.com/apache/beam/blob/release-2.3.0/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/spanner/MutationSizeEstimator.java > SpannerIO.write throws on delete mutations > ------------------------------------------ > > Key: BEAM-3569 > URL: https://issues.apache.org/jira/browse/BEAM-3569 > Project: Beam > Issue Type: Bug > Components: io-java-gcp > Affects Versions: 2.2.0 > Reporter: Oscar Korz > Assignee: Kenneth Knowles > Priority: Major > Fix For: 2.3.0 > > Attachments: beam-spanner-io-delete.tar.gz > > > It is currently impossible to delete a Spanner row in Beam with SpannerIO. > The exception is generated by trying to guess the size of a delete mutation > which cannot contain any values (deletes are simply by key). > The root exception stack trace: > {code:java} > Caused by: java.lang.IllegalStateException: values() cannot be called for a > DELETE mutation > at com.google.common.base.Preconditions.checkState(Preconditions.java:456) > at com.google.cloud.spanner.Mutation.getValues(Mutation.java:233) > at > org.apache.beam.sdk.io.gcp.spanner.MutationSizeEstimator.sizeOf(MutationSizeEstimator.java:33) > at > org.apache.beam.sdk.io.gcp.spanner.MutationSizeEstimator.sizeOf(MutationSizeEstimator.java:51) > {code} > I believe this can be fixed by special casing MutationSizeEstimator.sizeOf to > either 0 or 1 for Mutations with getOperation() = Op.DELETE. > The workaround is to avoid using SpannerIO and use Spanner client API > directly in a custom DoFn, but this forces users to either reimplement all > the intelligent batching that SpannerIO does or suffer poor performance. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
