Roman Puchkovskiy updated IGNITE-19770: --------------------------------------- Labels: iep-98 ignite-3 (was: ignite-3) > Add a mechanism to wait till a schema is available via Schema Sync at a ts > -------------------------------------------------------------------------- > > Key: IGNITE-19770 > URL: https://issues.apache.org/jira/browse/IGNITE-19770 > Project: Ignite > Issue Type: Improvement > Reporter: Roman Puchkovskiy > Assignee: Roman Puchkovskiy > Priority: Major > Labels: iep-98, ignite-3 > Fix For: 3.0.0-beta2 > > > According to IEP-98, when obtaining a schema at a timestamp T, we need to > wait till Meta-Storage SafeTime becomes >= T-DD. A mechanism for such waits > needs to be implemented. > Also, we will probably need to wait for a specific version of a > table/index/etc (or a version of a Catalog as a whole), so a way to wait for > it (and not for a ts) is also needed. > Both can be implemented either as methods like > {{CompletableFuture<TableDefinition> table(String tableName, HybridTimestamp > ts)}} (for each getting method) or a single method like > {{CompletableFuture<Void> waitForTs(HybridTimestamp)}} (then usual sync > methods to be used to get the definitions). -- This message was sent by Atlassian Jira (v8.20.10#820010)
