1. The challenge for contemporary blockchain data stack There are numerous obstacles that a modern-day blockchain indexing startup may face, consisting of: Massive quantities of data. As the quantity of information on the blockchain increases, the information index will need to scale up to manage the increased load and offer effective access to the information. As a result, it results in higher storage expenses, slow metrics computation, and increased load on the database server.Complex information processing pipeline. Blockchain technology is complex, and constructing a thorough and trustworthy data index needs a deep understanding of the underlying information structures and algorithms. The diversity of blockchain applications acquires it. Offered specific examples, NFTs in Ethereum are normally developed within smart contracts following the ERC721 and ERC1155 formats. On the other hand, the application of those on Polkadot, for instance, is normally constructed straight within blockchain runtime. Those must be considered NFTs and must be saved as those.Integration abilities. To provide optimal worth to users, a blockchain indexing solution might require to incorporate its information index with other systems, such as analytics platforms or APIs. This is tough and needs substantial effort placed into the architecture design.As blockchain technology has ended up being more extensive, the amount of information stored on the blockchain has actually increased. This is due to the fact that more people are utilizing the technology, and each deal adds brand-new information to the blockchain. Additionally, blockchain technology has actually progressed from easy money-transferring applications, such as those including making use of Bitcoin, to more intricate applications including the implementation of business logic within smart contracts. These smart contracts can create big quantities of information, adding to the increased complexity and size of the blockchain. Over time, this has caused a larger and more intricate blockchain.In this article, we review the evolution of Footprint Analytics ‘technology architecture in stages as a case research study to explore how the Iceberg-Trino technology stack addresses the challenges of on-chain data.Footprint Analytics has indexed about 22 public blockchain information,
and 17 NFT market, 1900 GameFi job, and over 100,000 NFT collections into a semantic abstraction data layer. It’s the most extensive blockchain data warehouse service in the world.Regardless of blockchain data
, that includes over 20 billions rows of records of monetary deals, which information experts often query. it’s different from ingression logs in conventional data warehouses.We have experienced 3 significant upgrades in the past a number of months to meet the growing company requirements:2. Architecture 1.0 Bigquery At the beginning of Footprint Analytics, we utilized Google Bigquery as our storage and query engine; Bigquery is a terrific product. It is blazingly quick, easy to utilize, and offers dynamic arithmetic power and a versatile UDF syntax that assists us rapidly get the task done.However, Bigquery also has numerous problems.Data is not compressed, leading to high costs, particularly when keeping raw data of over 22 blockchains of Footprint Analytics.Insufficient concurrency: Bigquery only supports 100 synchronised queries, which disagrees for high concurrency circumstances for Footprint Analytics when serving many analysts and users.Lock in with Google Bigquery, which is a closed-source item 。 So we decided to check out other alternative architectures.3.
Data types such as Array or JSON are not yet supported(Nov, 2022)
. Arrays are a common type
of information in some blockchains. For example, the subject
field in evm logs. Unable to compute on Array directly affects our ability to compute lots of organization metrics.Limited assistance for DBT,
- and for combine statements. These prevail requirements for information engineers for ETL/ELT scenarios where we require to update some newly indexed data.That being stated, we couldn’t use Doris for our whole data pipeline on production, so we tried to utilize Doris as an OLAP database to fix part of our problem in the data production pipeline, serving as an inquiry engine and providing fast and highly concurrent question capabilities.Unfortunately, we could not replace Bigquery with Doris, so we needed to occasionally synchronize
information from Bigquery to Doris utilizing it as an inquiry engine. This synchronization procedure had numerous concerns, one of which was that the update writes got accumulated quickly when the OLAP engine was hectic serving questions to the front-end clients. Subsequently, the speed of the writing process got affected, and synchronization took a lot longer and sometimes even ended up being difficult to finish.We realized that the OLAP could solve several problems we are facing and could not become the turnkey solution of Footprint Analytics, specifically for the data processing pipeline. Our issue is larger and more intricate, and we could say OLAP as a query engine alone was inadequate for us.4. Architecture 3.0 Iceberg+Trino Welcome to Footprint Analytics architecture 3.0, a total overhaul of the underlying architecture.
We have upgraded the entire architecture from the ground up to separate the storage, calculation and question of data into 3 various pieces. Taking lessons from the two earlier architectures of Footprint Analytics and learning from the experience of other successful big information tasks like Uber,
Netflix, and Databricks.4.1. Intro of
the information lake We first turned our attention to information lake, a brand-new type of information storage for both structured and unstructured data. Information lake is ideal for on-chain data storage as the formats of on-chain data range commonly from unstructured raw information to structured abstraction data Footprint Analytics is well-known for. We anticipated to utilize information lake to resolve the problem of data storage, and preferably it would likewise support traditional compute engines such as
Spark and Flink, so that it would not be a
pain to incorporate with various types of processing engines as Footprint Analytics evolves.Iceberg incorporates very well with Spark, Flink, Trino and other computational engines, and we can pick the most proper calculation for each of our metrics. For example : For those needing complex computational reasoning, Spark will be the choice.Flink for real-time computation.For basic ETL tasks that can be performed utilizing SQL, we utilize Trino.4.2. Query engine With Iceberg resolving the storage and computation problems, we had to think of selecting an inquiry engine. There are very few choices readily available. The options we considered were Trino: SQL Query Engine Presto: SQL Query Engine Kyuubi: Serverless Spark SQL The most important thing we considered before going deeper was that the future inquiry engine needed to be compatible with our current architecture.To support Bigquery as a Data Source To support DBT, on which we rely for numerous metrics to be produced To support the BI tool metabase Based upon the above, we selected Trino, which has excellent assistance for Iceberg and the team were so responsive that we raised a bug, which was fixed the next day and launched to the most recent variation the following week. This was the very best option
for the Footprint team, who likewise requires high implementation responsiveness.4.3. Efficiency screening When we had picked our direction, we did a performance test on the Trino+ Iceberg combination
- to seeif it could meet our requirements and to our surprise, the queries wereexceptionally fast.Knowing that Presto+ Hive has been
- the worst comparator for years in all
the OLAP buzz, the mix of Trino+Iceberg completely blew our minds.Here are the results of our tests.case 1: sign up with a large dataset An 800 GB table1 joins another 50 GB table2 and does complex service computations case2: use a big single table to do an unique question Test sql: select distinct(address)from the table group by day

combination is about 3 times faster than Doris in the exact same configuration.In addition, there is another surprise since Iceberg can utilize data formats such as Parquet, ORC, and so on, which
will compress and save the information. Iceberg’s table storage takes
only about 1/5 of the area of other data warehouses The storage size of the very same table in the three databases is as follows: Note: The above tests are examples we have encountered in real production and are for referral just.4.4. Update impact The performance test reports provided us enough performance that it took our team about 2 months to finish the migration, and this

Trino+Iceberg permits us to open all
Bronze information( raw information )to our users.5.
