Multichain 1.0.4 Data Streams: Is there a way to query with an array of transactions?

Wed, 01 Aug 2018 15:11:13 +0000

Is there a way to query multiple transactions using getstreamitem, in the same way we can query multiple keys using liststreamkeys?

I.e.;

multichain-cli chainName getstreamitems streamName '["6dc849c5e8257eaf9fcf4ddd27fef9f2c4e0c6717090bd7d1b9be986d945b92a", "5dff0d40021384dbca2a80ecac09c0f819556afd71cf68b0f45367fe5071d73e"]'

Thank you!

Find previous TxId applying to a particular key in a stream

Tue, 15 May 2018 08:26:25 +0000

I am treating a stream as a time-series, and using the Key to identify objects (which therefore have multiple transactions reflecting changes in state over time).

Is there a way to retrieve "adjacent" (next or previous) transaction against the same key, in the same stream?

I want to try avoid doing this by fetching all items by Key and figuring it out in memory.
